ion? Check all that apply.
Р
Fe
Pb
Se

Answer 1

b and c...will lose electron(s) in forming an Ion.

P is an Anion
b..Fe. and c...Pb form Cations (+) by losing electrons.
d. Se is an Anion.

Answer 2

Elements that will loose electron as so that ion can be formed are; Fe and Pb.

• Fe ( iron ) and Pb ( Lead)  are both metals and metals will always loose electron so that they can turn to postively charged ion, and this ion is regarded as Cation.

• Phosphorus (P) is a non- metal,  it will only gain electron and turn to a negatively charged ions, this ion is regarded as Anion.

Therefore, Metals usually lose electron while non- metals accept the electron.
