[3] Atomic Structure

What is a molecule?

A molecule is made up of two or more atoms chemically bonded together, either of the same or different elements.

What is an atom?

An atom is the smallest unit of an element, consisting of a protons, electron and neutrons

what is the charge of a proton neutron and electron

proton +1
electron -1
neutron 0

what is the relative mass of a proton electron and neutron

proton 1
neutron 1
electron 0.0005

what is an isotope

an element that has the same atomic number but different mass number

how do you calculate the RAM

RAM = (isotope 1 mass x abundance of isotope 1) + (isotope 2 mass x abundance of isotope 2) / 100
