Since calcium (Ca) is in Group 2 and oxygen (O) is in Group 16, the electron configuration for Ca is [Ar]4s² and for O is [He]2s²2p⁴. Calcium will lose 2 electrons to achieve a stable electron configuration of [Ar], while oxygen will gain 2 electrons to achieve a stable electron configuration of [He]2s²2p⁶. The electron shell diagram for calcium oxide (CaO) will show the transfer of these electrons from calcium to oxygen, resulting in Ca²⁺ and O²⁻ ions being attracted to each other electrostatically.

Is sodium floride ionic or convalent?
Sodium fluoride is an ionic compound. Sodium is a metal that donates an electron, and fluoride is a nonmetal that accepts the electron to form a stable ionic bond.
Which pair of atoms will form an ionic compound?
An ionic compound is formed when one atom donates an electron to another to achieve a stable electron configuration. For example, sodium (Na) will transfer an electron to chlorine (Cl) to form sodium chloride (NaCl), an ionic compound.
Which electron-dot diagram best represents a compound that contains both ionic and covalent bonds?
The best electron-dot diagram would show ionic bonds with transfer of electrons between atoms, and covalent bonds with sharing of electrons between atoms. Ionic bonds would be represented by complete transfer of electrons from one atom to another, while covalent bonds would be shown as overlapping of electron clouds between atoms.
Is CsBr an ionic compound?
Yes, CsBr (cesium bromide) is an ionic compound. It is composed of cesium (Cs) and bromine (Br) ions held together by ionic bonds, where Cs loses an electron to become a cation and Br gains an electron to become an anion.
Is sodium hydroxide a molecular or ionic compound?
Sodium hydroxide is an ionic compound. Sodium (Na) is a metal that donates an electron to oxygen (O) to form the ionic bond in sodium hydroxide (NaOH).
