Key Diagrams and Atomic Structure
This page provides visual representations of atomic structure and the differences between elements, compounds, and mixtures, enhancing understanding through graphical aids.
The main diagram illustrates the structure of an atom, highlighting:
- The nucleus at the center, containing protons and neutrons.
- Electrons orbiting the nucleus in layers called shells.
Example: The diagram shows how protons, neutrons, and electrons are arranged within an atom, with the positively charged protons and neutral neutrons clustered in the nucleus, while negatively charged electrons orbit in shells.
Additional diagrams differentiate between:
- Elements: Consisting of identical atoms.
- Compounds: Made up of different elements chemically bonded.
- Mixtures: Combinations of substances not chemically joined.
Highlight: The visual representation of atomic structure and atom diagrams helps students grasp the spatial arrangement of subatomic particles and the differences between various types of matter.
These diagrams are essential for students studying atomic structure at various levels, from Class 8 to Class 11, providing a clear visual aid to complement theoretical knowledge.
Law of Conservation of Mass and Advanced Concepts
This page delves into more advanced topics related to atomic structure and chemical reactions, including the law of conservation of mass, ions, and isotopes.
Definition: The law of conservation of mass states that the total mass of the products formed in a reaction must be equal to the total mass of the reactants.
Key points covered:
- Mass number calculation: number of protons + number of neutrons
- Elements can gain or lose electrons during chemical reactions, forming ions
Vocabulary: Ions are atoms or groups of atoms with an electrical charge, either positive or negative.
The page explains:
- Positive ions: Atoms that lose electrons, having more protons than electrons
- Negative ions: Atoms that gain electrons, having more electrons than protons
Highlight: In chemical reactions, the number of protons remains constant, while metals tend to lose electrons and non-metals tend to gain electrons.
Lastly, the concept of isotopes is introduced:
Definition: Isotopes are atoms with the same number of protons but different numbers of neutrons in their nucleus.
This page provides crucial information for understanding chemical reactions, ionic bonding, and the variations within elements, essential for students studying chemistry at higher levels.
Atomic Structure and Its Components
This page introduces the fundamental concepts of atomic structure, providing key definitions and explanations essential for understanding the building blocks of matter.
Definition: An atom is the basic building block for all matter in the universe.
The page outlines the three main components of an atom:
- Protons: Positively-charged particles found in the atom's nucleus.
- Neutrons: Particles with no charge (neutral) located in the nucleus.
- Electrons: Negatively charged particles that orbit the nucleus.
Vocabulary: The atomic number refers to the number of protons in an atom.
Additionally, the page introduces related concepts:
- Elements: Substances consisting of atoms with the same number of protons.
- Compounds: Two or more different elements joined chemically.
- Mixtures: Combinations of two or more pure substances.
Highlight: Understanding the differences between protons, neutrons, and electrons is crucial for grasping atomic structure and its implications in chemistry.
The page also mentions atomic mass, suggesting a relationship between neutrons, protons, and electrons, which is fundamental for calculating the mass and charge of atoms.

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.

Just amazing. Let's me revise 10x better, this app is a quick 10/10. I highly recommend it to anyone. I can watch and search for notes. I can save them in the subject folder. I can revise it any time when I come back. If you haven't tried this app, you're really missing out.

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 didnโt even know about this app three days until the exam and it has helped A LOT. Please actually trust me and use it as Iโm sure you too will see developments.
