Which of the following lists the correct symbol for the ion that tin forms when it loses 2 electrons, the correct classification
of the ion as an anion or a cation, and the name of the ion? a
Sn2+; anion; tin ion
b
Sn2+; cation; tin(II) ion
c
Sn2–; anion; tin(II) ion
d
Sn2+; cation; tin ion
Atoms of elements can either lose or gain electrons to become charged atoms i.e ions. An atom that loses electrons to become positively charged is called a CATION while one that gains electrons to become negatively charged is called an ANION.
In this case, tin element (Sn) loses 2 electrons to become positively charged with a charge number of 2 i.e Sn2+. Since it is a positively charged ion, it is called a CATION and named Tin (II) ion.
