I need help with atomic numbers can you please teach me and tell me the answer you will get 10 points

Explanation:

The number of protons and neutrons together create total atomic mass.

The number of protons determine what element it is on the Periodic Table.

The number of electrons v protons determine the charge of the atom.

Protons are positive, electrons are negative, neutrons have no charge.

Since there is 1 more electron than protons, the overall charge is going to be -1.

We are given that there are 3 protons, so that gives us the Lithium element with a -1 charge.

Add up the 3 protons with the 3 neutrons and we get 6 as the total atomic mass in this atom.

1. they vary with a higher number because boiling is way hotter than melting
