You can find the charge of a nucleus by counting the number of protons, if you are looking for the charge of the atom over all you can then subtract the number of electrons. If your answer is positive you have an excess of protons and thus a positive atom and if negative you have an excess of electrons thus a negatively charged atom. 0 means both are balanced.
Count the protons, then subtract that number by the number of it's electrons. There's your positive ionic charge.
the nuclear charge experienced by valence or outer-shell electrons, diminished by the shielding effect of inner-shell electrons and also by the distance from the nucleus
I would have surely answered if I knew
Aluminum ions are positive, and have three neutrons in it.
of course it does
It would depend on the isotope.
electrons have negligible mass. the mass of the ion depends on how many protons and neutrons are present.
Protons and Neutrons.
It has 12 neutrons.
Aluminum ions are positive, and have three neutrons in it.
Li-6 has 3 neutrons and Li-7 has 4 neutrons.
Li-6 has 3 neutrons and Li-7 has 4 neutrons.
Na+ sodium ion has 11 protons, 12 neutrons and 10 electrons
The hydrogen ion H+ has no neutrons.
Sodium has 12 neutrons. Chloride ion has 18 neutrons. In a formula unit, NaCl has 30 neutrons.

The mass number for iodine is 131, which is the sum of the protons and neutrons. Iodine has 53 protons and 53 electrons, if neutral. To find how many neutrons iodine has subtract 53, the number of protons from the mass number of 131. This shows that iodine has 78 neutrons.
It depends on which isotope of chlorine you're interested in.
