C1 Chemistry Revision - Atoms, Elements, Compounds & Equations for GCSE
amxrioffside
@theamarissa_snm
Page 2: Chemical Equations and Conservation of Mass
This page focuses on understanding chemical equations and reactions, a key topic in C1 chemistry. It explains how to write and balance chemical equations, and introduces the concept of conservation of mass.
Chemical equations are described as representations of reactions, showing reactants and products. The page emphasizes that in chemical reactions, atoms are rearranged rather than created or destroyed.
Example: The formation of water is shown as a chemical equation: H₂ + O₂ → H₂O
The importance of using symbol equations is highlighted, as they help visualize the quantities of substances involved in a reaction.
Highlight: Balanced equations are crucial because they reflect the law of conservation of mass.
The page explains that the number of each type of atom must be the same on both sides of the equation for it to be balanced. This principle is linked to the conservation of mass, stating that the total mass of the products equals the total mass of the reactants in a chemical reaction.
Vocabulary: State symbols are introduced to provide additional information in chemical equations:
- for solid
- for liquid
- for gas
- for aqueous
An example of a balanced equation with state symbols is provided:
Example: CaCO₃ → CaO + CO₂
This page is essential for students preparing for GCSE Chemistry balancing equations and understanding the principles of chemical reactions. It provides a solid foundation for more advanced topics in chemistry and is valuable for both BBC Bitesize GCSE revision and classroom learning.
Page 1: Atomic Structure and the Periodic Table
This page covers the fundamental concepts of atoms, elements, compounds, and mixtures, as well as the structure of atoms and the organization of the periodic table.
Definition: An atom is the smallest part of an element that can exist.
The page explains that all substances are made of tiny particles called atoms. It distinguishes between elements, compounds, and mixtures:
- Elements consist of only the same type of atoms
- Compounds are made up of two or more different types of substances chemically bonded together
- Mixtures contain two or more different types of substances that aren't chemically bonded and can be separated physically
Highlight: The atomic structure is detailed, showing protons and neutrons in the nucleus, with electrons orbiting in shells.
A table is provided showing the relative charge and mass of protons, neutrons, and electrons:
Example:
- Proton: Charge +1, Mass 1
- Neutron: Charge 0, Mass 1
- Electron: Charge -1, Mass 1/1800
The periodic table's organization is explained:
- Separated by a staircase to distinguish metals from non-metals
- Vertical columns are called groups
- Horizontal rows are called periods
Vocabulary: Atomic number refers to the number of protons in an atom, while atomic mass is the total number of protons and neutrons.
The page concludes with information on electron configurations and how elements in different groups gain or lose electrons:
- Group 1 loses 1 electron
- Group 2 loses 2 electrons
- Group 3 loses 3 electrons
- Group 5 gains 3 electrons
- Group 6 gains 2 electrons
- Group 7 gains 1 electron
This information is crucial for GCSE Chemistry C1 revision and understanding the periodic table groups and periods.

The app is very easy to use and well designed. I have found everything I was looking for so far and have been able to learn a lot from the presentations! I will definitely use the app for a class assignment! And of course it also helps a lot as an inspiration.

Wow, I am really amazed. I just tried the app because I've seen it advertised many times and was absolutely stunned. This app is THE HELP you want for school and above all, it offers so many things, such as workouts and fact sheets, which have been VERY helpful to me personally.

This app has made me feel so much more confident in my exam prep, not only through boosting my own self confidence through the features that allow you to connect with others and feel less alone, but also through the way the app itself is centred around making you feel better. It is easy to navigate, fun to use, and helpful to anyone struggling in absolutely any way.

The app's just great! All I have to do is enter the topic in the search bar and I get the response real fast. I don't have to watch 10 YouTube videos to understand something, so I'm saving my time. Highly recommended!

very reliable app to help and grow your ideas of Maths, English and other related topics in your works. please use this app if your struggling in areas, this app is key for that. wish I'd of done a review before. and it's also free so don't worry about that.

I know a lot of apps use fake accounts to boost their reviews but this app deserves it all. Originally I was getting 4 in my English exams and this time I got a grade 7. I didn’t even know about this app three days until the exam and it has helped A LOT. Please actually trust me and use it as I’m sure you too will see developments.

This apps acc the goat. I find revision so boring but this app makes it so easy to organize it all and then you can ask the freeeee ai to test yourself so good and you can easily upload your own stuff. highly recommend as someone taking mocks now
