Aluminium, Al
A certain element forms an ion with 10 electrons and a charge of +2. Identify the element
It is called an Ion.
All elements have electrons, when the amount of electrons they have changes they are called ions. They only element that forms an ion with no electrons is Hydrogen (H). To learn more about electrons and ions you should inquire about electron configuration.
Rhodium (Rh) forms a 3 plus ion that has the electron configuration Kr4d6. Rhodium has oxidation states of 2,3 and 4, so it can loan out 2, 3 or 4 electrons depending on the circumstances of a chemical reaction.
[Kr]4d6 ion has 42 electrons. As it is a 3+ ion, the parent atom would have 45 electrons. This would make it Rhodium Rh.

The answer is 3. Fe -> Fe3+ + 3e
Lead lose two electrons and silver lose one electron.
S
Calcium
[Kr]4d6 ion has 42 electrons. As it is a 3+ ion, the parent atom would have 45 electrons. This would make it Rhodium Rh.
+2 (plus 2)
The chloride ion has 18 electrons.
The third period element that forms a 3- ion is sulfur.
