Question

1. the diagram represents the electron dot formula for the bonding of mg and cl. which of the following are true for the bonding type involved in mgcl? select two correct answers. the two electrons that the mg atom loses are gained by the chlorine atom. the two elements join together in an ionic bond. the one electron that the mg atom loses is gained by the chlorine atom. the two elements join together in a covalent bond. the two elements join together in a hydrogen bond

Explanation:

• Magnesium (\(Mg\)) is a metal and chlorine (\(Cl\)) is a non - metal. Ionic bonds form between metals and non - metals.
• In \(MgCl_2\), \(Mg\) loses 2 electrons (as it has a + 2 charge in the compound). Each \(Cl\) atom gains 1 electron (since \(Cl\) has a - 1 charge in the compound).
• The two electrons that the \(Mg\) atom loses are gained by the two chlorine atoms.
• The bond between \(Mg\) and \(Cl\) in \(MgCl_2\) is an ionic bond.

Answer:

• The two electrons that the \(Mg\) atom loses are gained by the chlorine atom.
• The two elements join together in an ionic bond.
