Question 1

Which of the following best describes an ionic compound?

Accepted Answer

A neutral compound made up of ions of a metal with a nonmetal where there is a transfer of electrons.

Question 2

In the formation of sodium chloride ($$\mathrm{NaCl}$$), what happens to the sodium atom?

Accepted Answer

It gives up one electron to become $$\mathrm{Na^+}.$$

Question 3

Which of the following is the correct definition of a cation?

Accepted Answer

A metal ion that gives up electrons and has a positive charge.

Question 4

What is the charge on the chloride ion in $$\mathrm{NaCl}$$?

Accepted Answer

$$-1$$

Question 5

Which of the following elements is most likely to form an anion in an ionic compound?

Accepted Answer

Chlorine ($$\mathrm{Cl})$$

Question 6

Why do ionic compounds like $$\mathrm{NaCl}$$ have no overall charge?

Accepted Answer

The total positive charge of the cations equals the total negative charge of the anions.

Question 7

Accepted Answer

$$\mathrm{$$MgCl_2$$}$$

Question 11

Which of the following best describes the electron transfer in the formation of an ionic bond?

Accepted Answer

Electrons are transferred from the metal to the nonmetal.

Question 12

Which of the following ions is most likely to be found in an ionic compound formed with potassium ($$\mathrm{K}$$)?

Accepted Answer

$$\mathrm{K^+}$$

Question 13

Which of the following is NOT a property of ionic compounds?

Accepted Answer
