Protons are positively electrically charged
Electrons are negatively electrically charged
Neutrons are neutrally electrically charged
An atoms first shell can hold 2 electrons; second and third shell 8 electrons; fourth and fifth shell 16 electrons; sixth and seventh shell 36 electrons
An atoms core contains an equaled amount of neutrons and protons
A neutrally electrically charged atom contains an equaled amount of neutrons, protons and electrons
A positively electrically charged atom has less electrons than the core has of protons and neutrons
A negatively electrically charged atom has more electrons than the core has of protons and neutrons
Chemical formulas (using algebratimatimized (NEW WORD YAY) letters, not chemical formulas for atoms):
Positively loaded atom: X(y)⁺
Negatively loaded atom: X(y)^-
Neutrally loaded atom: X(y)
2+X numbers of same atoms: X(y)_z
2+X numbers of different atoms: X(y)A(b)...
If an atoms outermost shell lacks one or more electrons, it will seek for other atoms's incomplete outermost shells and 'borrows' electrons to fill its own incomplete outermost shell
If one or more atom(s) is/are positively electrically charged and one or more other atom(s) is/are negatively electrically charged, they will snatch together and cause a covalent bond. (electronpaircombining)
Example of a covalent bond: CO₂; The oxygen atoms's outermost shells lacks two electrons (2+6 electrons each), causing them to try borrowing the carbon atom's four outermost electrons (2+4 electrons), while the carbon atom seeks for electrons from the oxygen atom's outermost shell to fill its outermost shell, which lacks of 4 electrons, causing the atoms to bind together
The period-line in the periodic system tells how many shells the atoms has on its row
Column number eighteen in the periodic system shows noble gases

I think that should be all.

Science FTW.
