The atomic number of hafnium is 72. So there is 72 protons.
Electrons have a negative charge, and protons have a positive charge. If i have more protons(plus charges) than electrons(minus charges) overall the atom will have a positive charge(mabye +1 or +2 etc....depending how many more protons there are compared to electrons) If there are more electrons(minus charges) than protons(plus charges) then overall the atom will have a negative charge(mabye -1 or -2 etc....depending how many more electrons there are compared to protons) These charged atoms are known as ions.
Lead will always have 82 protons. If it has a 2+ charge, that means there are 2 more protons than electrons, so there are 80 electrons.
All lithium atoms and ions have three protons. The lithium ion has a charge of +1, meaning there is one less electron than protons, two.
No element or ion as stated can exist, because if it contains 23 protons and only 18 electrons, its net charge must be 23 - 18 = 5 plus, not 3 plus.
If you mean the charge of an alpha particle, it's +2 since they're made up of 2 protons and 2 neutrons, protons having plus 1 charge, neutrons having 0.
6 Charge and mass do not change this answer.

hey perhaps your question is incomplete. but if your question is what is protons and neutron relationship then a neutron plus a positive charge having mass equal to electron mass then proton forms.
The number of protons is 2.
Mn has 25 protons.
Charge would be 1+ (2+ plus 1- = 1+)
Because protons have a positive charge, hence the plus sign, and electrons have a negative charge, hence the minus sign.
If a neutral atom gains electrons it is called what?
