Which of the following statements is false? a) anions are usually larger than their corresponding atom. b) metals tend to form cations. c) atoms are usually larger than their corresponding cation. d) the halogens tend to form 1+ ions. e) nonmetals tend to gain electrons.

D) The halogens tend to form 1+ ions.

Explanation:

A) Is correct because the atom gains an electron

B) Is correct because metals tends to lose electrons

C) Is correct because the atom loses an electron

D) Is incorrect because the halogens tends to gain electrones (1-)

E) Is correct because Nonmetals tend to form anions

The correct answer is option D) The halogens tend to form 1+ ions.

Explanation:

Hello!

Let's solve this!

We will analyze each of the options:

A) Anions are usually larger than their corresponding atom: it is correct because when the atom has more electrons, and it is an anion, it increases its size more.

B) Metals tend to form cations: it is correct, because metals tend to yield their electrons by charging positively and therefore, form cations.

C) Atoms are usually larger than their corresponding cation: it is correct since cations are the ions that have lost electrons, thus decreasing their size.

D) The halogens tend to form 1+ ions: it is not correct, since halogens form 1- ions, they form anions, since they are nonmetals.

E) Nonmetals tend to gain electrons: it is correct since nonmetals tend to accept electrons and form anions.

After the analysis we conclude that the correct answer is option D) The halogens tend to form 1+ ions.
