As with the majority of atoms in the transition metals section of the Periodic Table, Rhenium has a charge of 2+ when ionized, written as Re2+. Some exceptions to this rule are Silver (Ag+), and Gold (Au+) ions. There is also the occasional element that will form ions in many different ways, such as Mercury (There can be Hg+ and Hg2+ ions).
1 or 2 valence electons (you can't find the exact number in transition metals and the answer is always 1 or 2)
The valency of rhenium is 7.
+3
The ionic charge of Californium is 3+.
Phosphite has an ionic charge of -3.
In ionic chlorine compounds, the ionic charge of chlorine is -1.
The ionic number is the positive or negetive charge an element has, such as Lithium has an ionic charge of +1.
Zero. A compound will never have a net ionic charge.
A little more information is needed. Rhenium is a transition metal, and as such, can have multiple valence states. If an ionic charge is known, for example, +2, then it can be assumed that the formula for the oxide would be RhO. If percent composition by mass is known, for example, 86.5% rhenium by mass, then math can be done to determine the formula of the oxide, which in this case, would also be RhO.
Phosphite has an ionic charge of -3.
The ionic charge of Californium is 3+.
In ionic chlorine compounds, the ionic charge of chlorine is -1.
The ionic number is the positive or negetive charge an element has, such as Lithium has an ionic charge of +1.
Zero. A compound will never have a net ionic charge.
The net charge of any ionic compound is zero, in other words, ionic compounds are neutral.
The Ionic charge of H2O is 0 because H has a +1 charge and there are two H so it equals +2 and O has a -2 charge. So they balance out to a charge of zero
The net charge of an ionic compound is equivalent to zero.
Rubidium belongs to Alkali metals so its ionic charge is +1.
+2 charge
a negative charge
