Fundamental Biomolecules

this is fucking chemistry??

Hydrogen

Atomic Number 1

1 proton, 0 neutrons, 1 electron

Carbon

Atomic Number 6

6 protons, 6 neutrons, 6 electrons

The number of neutrons may vary, which leads to isotopes which can be unstable

Can form 4 bonds

Nitrogen

Atomic Number 7

7 protons, 7 neutrons, 7 electrons, again neutrons can change and make isotopes

Can form 3 bonds

Oxygen

Atomic Number 8

8 protons, 8 neutrons, 8 electrons

Can form 2 bonds

Phosphorus

Atomic Number 15

15 protons, ~15 neutrons, 15 electrons

Can form 3 bonds

Sulfur

Atomic Number 16

16 protons, ~16 neutrons, 16 electrons

Can form 2 bonds

Octet rule

Only 8 electrons can be in the outer shell, all elements except H and He want to have 8 electrons
