Subatomic particles
Neutron, protons and electrons
Cation
Has a positive charge
Anion
Has a negative charge
Hydrogen bonds
weak + charge that’s electrostatically ❤️ to another atom with a weak charge
Neutron has
No charge
Proton
Has a positive charge
Electron has
Negative charge
Electron
Forms a cloud and has atomic nucleus
Atoms
Is the smallest unit of matter
Ionic bonds
Forms when opposite atoms are ❤️ to each other
Covalent bond
two atoms share a pair of electrons to fill up their outer electron shells and become more stable.
Non polar covalent bonds
shared electrons are evenly distributed between the atoms
Valance shell
Catalytize atom in chemical reactions
Full valence shell
Stable
Empty valance
Is reactive
