Question

which of the following are true for the compound cacl₂? select two correct answers. its name is calcium chloride. it forms a covalent bond. it forms a metallic bond. it forms an ionic bond. its name is calcium chlorite.

Explanation:

• For naming: In ionic compounds, the metal (Ca - calcium) is named first, then the non - metal (Cl - chloride). So \(CaCl_2\) is calcium chloride.
• For bonding: Calcium (\(Ca\)) is a metal (loses electrons to form \(Ca^{2+}\) ions) and chlorine (\(Cl\)) is a non - metal (gains electrons to form \(Cl^{-}\) ions). Ionic bonds form between metals and non - metals through the transfer of electrons. Covalent bonds form between non - metals (sharing electrons) and metallic bonds form between metal atoms.

Answer:

• Its name is calcium chloride.
• It forms an ionic bond.
