Match the following statements to the correct answer

Question

An element (or group of atoms) that has fewer electrons than protons.

An element (or group of atoms) that has more electrons than protons.

The type of bonds that NaOH contain.

In the compound KBr, potassium (K) is the _______________.

a. cation

b.anion

c.ionic

Answer 1

An element (or group of atoms) that has fewer electrons than protons. A. Cation

An element (or group of atoms) that has more electrons than protons. B. Anion

The type of bonds that NaOH contain.  C. Ionic

In the compound KBr, potassium (K) is the A. Cation

Explanation:

A cation is an atom that has a positive charge.

An anion is an atom that has a negative charge.

Ionic bonds form when a cation and an anion are attracted together based on their opposite charge.

In the compound KBr, K has one valence electron, and therefore wants to lose an electron. Losing a negative electron gives K a positive charge. Br has 7 valence electrons, and therefore wants to gain one electron. Gaining a negative electron gives Br a negative charge.
