Question

Name the element, which forms an ionic compound with chlorine.

Answer 1

Answer:

sodium will be the answer.....

Answer 2

Answer:

Cacl2 calcium chloride.

Explanation:

1)Ionic compounds generally form between elements that are metals and elements that are nonmetals.

For example,

the metal calcium (Ca) and the nonmetal chlorine (Cl) form the ionic compound calcium chloride (CaCl2).

In this compound, there are two negative chloride ions for each positive calcium ion.

2)Since each chlorine atom gained an electron, they each have 17 protons and 18 electrons. This makes each chloride a negative ion with a charge of −1. Oppositely charged ions attract each other, forming an ionic bond.

3)On the right, the chloride ion has 18 electrons and has a 1− charge. With two oppositely charged ions, there is an electrostatic attraction between them because opposite charges attract.
