Cobalt is difficult to predict the most probable ionic charge due to the fact that it has various oxidation states.
I predict that an ion of sodium will have a charge of plus one.
Group IA: +1 charge Group II2: +2 charge Group IIIB: +3 charge Group IVB: +4 charge Group VB: -3 charge Group VIB: -2 charge Group VIIB: -1 charge
Oxygen ion has a charge -2
a group that forms anions with a -1 charge
atomic radius
You can predict it's physical state, atomic size, atomic weight, electron effinity, charge, and other physical characteristics.
because it belongs in group 6 of the periodic table. To be able to have a full outer shell of 8, it will accept 2 electrons
All of the elements in column six of the periodic table have a 2- charge
No. The position of an element in the periodic table cannot predict the number of isotopes it has. However, the position of an element in the periodic table can predict other properties like the charge of its ion, the formula of its oxide, the acidic or basic nature of its oxide, etc.
If they're in the same group (vertical column) on the periodic table, then they will have the same charge. It's based on how many valence electrons they have. The periodic table is organized this way to make it easy to predict things like reactivity.

Elements, as they appear on the Periodic Table, have no net charge. They all have equal numbers of protons (+) and electrons (-). HOWEVER, an atom can gain or lose electrons, which will change its charge, but, again, on the periodic table, they all have 0 charge.
The rule of zero charge helps you predict the formula of an ionic compound because you know that what anion is present, the action that bonds will make the net charge zero.
The number of electrons are required to predict the charge of the ion.
