Question 6

What is the proton number/atomic number?

Answer 6

The proton number of an atom is the number of protons in its nucleus. (It is the same as the electrons

Question 7

The number of electrons that have been lost in a positive ion AND the number of electrons have been gained in a negatively charged ion.

Question 9

What are isotopes ?

Answer 9

Isotopes are atoms of the same element that have the same proton number but different nucleon numbers. This means that they have different numbers of neutrons.
