5 How many magnesium atoms and how many chlorine atoms react to form one formula unit of magnesium chloride Why What is the formula of

Answer :

  • Magnesium Chloride(MgCl₂) is formed from two of atoms Chlorine and one atom of Magnesium.

  • Magnesium chloride is an electrovalent or ionic compound because the electrons are unequally shared.

  • Magnesium Sulfide is formed from the combination of Mg with a 2+ charge and a Sulfur with a 2- charge thereby resulting in an overall charge of zero which is fairly stable.

  • The formula of the ionic compound formed by magnesium and phosphorus (P) atoms is Magnesium Phosphide Mg₃P₂.

Properties of Magnesium Phosphide

The properties include the following

  • It is thermally stable.
  • The electrons move to the Phosphide ion as a result of a greater electron affinity.

Answer:

5) Magnesium Chloride is MgCl2 because Mg is a 2+ charge and Cl is a -1 charge, meaning you need two Cl for every 1 Mg.

4) Magnesium chloride is an ionic compound because the electrons are unequally shared. The electrons tend to lean to the chloride ion, since it is has a greater electron affinity. The atoms are held together by electrostatic attractions between the positively and negatively charged particles.

7) Magnesium Sulfide is the combining of Mg with a 2+ charge, and a Sulfur with a 2- charge. Overall charge is zero, it is fairly stable and the electrons go to sulfur due to it having a greater electron affinity.

8) Magnesium Phosphide Mg3P2. Since Mg is 2+, and Phosphorous is 3-, you need them to balance so you want 3, 2+ and 2, -3 to make a total of 6+ and 6-. It is the most stable because it is an even charge and it allowed both ions to fill up the octet rule, by giving electrons from Mg, to receiving them from P. Overall charge 0. The electrons go to the Phosphide ion because it has a greater electron affinity.

Hope this helps!
