Atoms

Atoms

1. Atoms consist of a nucleus made of protons and neutrons orbited by electrons

2. Protons are an elementary particle that is identical with the nucleus of the hydrogen atom,

3. An electron is a negatively charged subatomic particle.

4. Neutron, neutral subatomic particle that is a constituent of every atomic nucleus except ordinary hydrogen

5. A group of electrons circulating around a nucleus or a molecule.

6. he octet rule states that atoms tend to form compounds in ways that give them eight valence electrons and thus the electron configuration of a noble gas.

7. The Lewis dot structure it is used to show how the electrons are arranged around individual atoms in a molecule. Electrons are shown as "dots" or for bonding electrons as a line between the two atoms
