mg and cl are element abrieviations. most common in chemistry. mg is magnesium and cl is chlorine. you will find them on a periodic table where elements are graphed depending on atomic mass and number, also buy there rate of reaction.
Mg(s) + 3/2 O2(g) + C(s) ----> MgCO3(s)
Balanced equation first.Mg + Cl2 -> MgCl2All is one to one, so,0.25 moles of chlorine ions are needed here.================================
Mg2+ + 2 Cl- are in 1 : 2 ratio (of ions) so also 0.25 : 0.50 mole ratio
magnesium and fluorine will formthe ionic compound, MgF2
MgCl2 because although K has a higher mass than Mg, the Mg compound with Cl has two atoms of Cl not one.
From the given elements, Mg has the largest atomic radius, hence the size.
There are 1 Mg and 2 Cl.
Ionic- the difference in electronegativity is high (Mg 1.31, Cl 3.16)
Mg-Cl and K-I

MgCl2
Magnesium (Mg) and Chlorine (Cl)
MgCl2
Cl
how many mg in 20 meg potassium
The high difference in electronegativity between Mg and Cl, and the fact that Mg is a metal and Cl is a non-metal, means that it's an ionic bond. Magnesium has two valence electrons; one chlorine takes one of them, another chlorine takes the other. The formula is therefore MgCl2.
