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.
I think the correct answer from the choices listed above is option D. Simple diffusion is the cell transport that allows small molecules to move from an area of higher concentration to an area of lower concentration without energy being <span>required from the cell.</span>
