Question

when a metal combine chemically with chlorine the compound formed is .............

Answer 1

metal chloride. eg:- sodium chloride (NaCl)

Answer 2

HELLO THERE!

Some basic notes:

=> When a metal combines with a non-metal, an electrovalent bond is formed.

=> Metal donates electron(s) and non-metal accepts it (according to their valencies).

According to your question, a metal is combining with a non-metal. This will form metallic chloride, with an electrovalent (ionic) bond.

Mechanism: Let's take Potassium chloride as an example.

Potassium (K-19) has 1 electron in its outermost (valence) shell. To attain complete octet (stability), it donates one electron.

Chlorine (C-17) has 7 electrons in its outermost shell. To attain complete octet, it requires one more electron, which it accepts from potassium.

Thus, the result is Potassium chloride, a metallic chloride.

THANKS!
