Atomic structure

What is the charge and mass of each subatomic particle

Proton=+1, 1

Neutron=0, 1

Electron=-1, 1/2000

Where is the proton number

Bottom it also represents electrons

What is the mass number

Protons + neutrons

What is key about ions

There charge changed the electrons +=loss, -=gain

What is an isotope

Same number of protons and electrons but different number of neutrons

What is the relative isotopic mass

The mass of the atom of an isotope compared with 1/12th of the mass of an atom of carbon 12

What is the relative atomic mass

The weighted mean mass of an atom compared to 1/12th the mass of an atom of carbon 12

Explain a spectrometry graph

Most abundant of has the highest relative abundance but heaviest has the lowest, number of bars=number of isotopes
