question 29 (2 points)
mgo (magnesium oxide)
a ionic
b covalent

Explanation:

Magnesium oxide (\(MgO\)) is formed by the transfer of electrons from magnesium (\(Mg\), a metal) to oxygen (\(O\), a non - metal). In ionic compounds, there is a complete transfer of electrons from the metal to the non - metal. Magnesium loses two electrons to form \(Mg^{2 +}\) and oxygen gains two electrons to form \(O^{2-}\). The electrostatic attraction between \(Mg^{2+}\) and \(O^{2 -}\) ions holds the compound together. In covalent compounds, electrons are shared between atoms (usually non - metals). Since \(MgO\) has a metal and a non - metal with electron transfer, it is not covalent.

Answer:

A. Ionic
