Hi there.
00:03
This question is about ionic compounds.
00:06
And if you recall, ionic compounds are formed between a metal and a non -metal.
00:15
When the metal loses one or more electrons, and the non -metal gains one or more electrons.
00:31
So the metal loses electrons, and the non -metal gains electrons.
00:38
Electrons are transferred.
00:44
And the number of electrons given up or lost by the metal needs to equal the number of electrons gained by the non -metal.
00:54
So for example, if we have magnesium, magnesium has two valence electrons.
01:02
So i am going to do the dot diagram here.
01:06
And if magnesium wants to form a compound with chlorine, chlorine is a halogen, and it has seven valence electrons, well, chlorine can accept one of the electrons for magnesium, but magnesium still has another electron to lose.
01:28
And the compound is only composed of magnesium and chlorine...
