Madlen writes five question types with answers, explanations and, for GCSE and A level, a mark scheme.
The examples below were generated in Madlen.
Metals have a specific type of structure. In this structure, atoms lose their outer shell electrons. These electrons move freely throughout the whole metal sample.
Which description best explains the bonding found in a metallic lattice?
Solution: Metallic bonding consists of a giant lattice of positive metal ions. These ions are surrounded by a sea of delocalised electrons that are free to move. The strong electrostatic attraction between these positive ions and the delocalised electrons holds the structure together. Covalent bonds involve sharing electron pairs, while ionic bonds involve the transfer of electrons between atoms. A mixture contains different substances that are not chemically bonded.
Different substances conduct electricity in different ways. Some materials allow electricity to pass through them because they have particles that can move and carry a charge.
Why do metals show good electrical conductivity in the solid state?
Solution: Metals are good conductors of electricity because the delocalised electrons are free to move through the giant metallic lattice when a voltage is applied. In contrast, simple molecular compounds like water or methane have no free electrons or ions to carry a charge, making them poor conductors. Ionic compounds only conduct when molten or aqueous because the ions are then free to move, but not in the solid state. Graphite is a non-metal that conducts, but most non-metals do not.
Metals can be hammered into thin sheets or pulled into long wires. This is possible because of the way the particles are arranged and how they react to pressure.
What allows a metal to be malleable and change shape without breaking?
Solution: Metallic lattices are malleable and ductile. This is because the layers of positive ions can slide over each other when a force is applied. The sea of delocalised electrons moves with the ions, so the metallic bond is not broken. In giant covalent structures like diamond, the bonds are rigid and break if the atoms move, making them brittle. Compounds and mixtures have different physical properties based on their specific compositions.
Metals have a special structure. They have positive ions in a giant lattice. Electrons move freely around these ions. We call this a sea of delocalised electrons.
Metals can conduct electricity because they have a sea of delocalised electrons that can move.
Solution: Metallic bonding involves an attraction between positive metal ions and a sea of delocalised electrons. These electrons can move through the lattice, which allows the metal to conduct electricity.
Metals are very strong but also flexible. You can change the shape of a metal. This is because the layers of ions can slide. The attraction between ions and electrons stays strong.
The property called malleability means that a metal is very brittle and breaks easily when you hit it.
Solution: Malleability is the property that allows a metal to be hammered into sheets without breaking. This happens because the layers of metal ions can slide over each other while the delocalised electrons maintain the bond.
Gold and oxygen are common substances. They have only one type of atom. A substance with only one type of atom is an ________.
Answer: element
Solution: An element is a pure substance. It contains only one kind of atom. Gold and oxygen are examples of elements.
Salt and sand are in a box. They are together but they are not joined. You can separate them easily. This is a ________.
Answer: mixture
Solution: A mixture contains different substances. These substances are not joined together. You can separate a mixture easily by physical ways.
The Periodic Table organises elements based on their atomic structure. The proton number determines the identity of the atom. The number of shells and outer electrons determine an element's position in periods and groups.
A sodium atom has 11 protons. Explain the electronic configuration of this atom and identify its position (period and group) on the Periodic Table.
Sample answer: A sodium atom has a proton number of 11. It has 11 electrons. The electronic configuration is 2,8,1. It has three occupied electron shells, so it is in Period 3. It has one electron in its outer shell, so it is in Group I.
Marking criteria:
Elements like carbon can have atoms with different masses. These atoms are called isotopes. Although their nuclei differ in neutron count, their chemical behaviour remains identical in most reactions.
Define what isotopes are and explain why different isotopes of the same element show the same chemical properties.
Sample answer: Isotopes are atoms of the same element. They have the same number of protons but different numbers of neutrons. Isotopes of the same element have the same chemical properties. This is because they have the same number of electrons and the same electronic configuration.
Marking criteria:
Ionic compounds like sodium chloride form when different types of elements react. These substances have a regular arrangement of ions called a giant lattice. Their bonding affects their physical state and properties.
Describe how an ionic bond is formed between a metal and a non-metal and explain why ionic compounds usually have high melting points.
Sample answer: Ionic bonds form when a metal atom gives electrons to a non-metal atom. This creates positive ions and negative ions. An ionic bond is a strong attraction between these oppositely charged ions. These compounds have high melting points because the attractions in the giant lattice are very strong and need a lot of energy to break.

The alignment mode links each question to the National Curriculum objective or specification point it assesses. You can see at a glance which question measures what and balance the quiz across topics.
Madlen knows that describe is not explain. GCSE and A level questions use the right command word, carry an AO tag and marks, and open-ended answers are marked against a levels-of-response mark scheme.
Mix multiple choice, true/false, fill-in-the-blank and matching questions with open-ended ones. Open-ended questions come with a sample answer and marking criteria with points.
A question set aligned to your exam board takes five steps in Madlen. The options below come from the form on the platform.
KS1 to KS3 follow the National Curriculum, KS4 is GCSE and KS5 is A level. For GCSE and A level you also pick the exam board, then the subject from its specifications.
Select one or more learning objectives from the specification so every question lines up with it.
Choose how many questions you want of each type and which assessment objectives each type should target. A set holds up to 30 questions.
Choose the command words the board uses, or leave it empty and Madlen picks them. Words such as evaluate and justify come with a levels of response mark scheme.
The questions come with a mark scheme. Edit anything you like and download the set as PDF or Word for your lesson.
Yes. Madlen’s free plan for individual teachers includes the question generator, with no credit card required. Every new account also starts with 14 days of Pro, and you can compare every plan on the Madlen pricing page.
In Madlen you choose the subject, the level and the learning objective, then pick the question types you need. Madlen writes the questions with answers, explanations and marks. You review the quiz, edit anything you like and download it.
Standards-aligned questions are written to assess one specific learning objective or specification point. Madlen links each question to the objective it measures, so you can see what a quiz covers and spot any gaps before you set it.
Yes. Madlen writes exam-style questions aligned to AQA, Edexcel, OCR and WJEC specifications, from KS3 through GCSE and A level. Each question uses the right command word, is tagged to an Assessment Objective and comes with a levels-of-response mark scheme, so it reads like a past paper rather than a worksheet.
Madlen creates multiple choice, open-ended, true/false, fill-in-the-blank and matching questions. It can also write context-based questions that test how well a pupil applies knowledge in an unfamiliar situation.
Every new account starts with 14 days of Pro, so you can try the tools on this page with your own classes.
