Question

periodic table of elements
which of the following are true for the compound ( cacl_2 )?
select two correct answers.
its name is calcium chloride.
it forms an ionic bond.
it forms a covalent bond.
its name is calcium chlorite.
it forms a metallic bond.

Explanation:

• Ionic Bond: \(CaCl_{2}\) is formed between a metal (calcium, \(Ca\)) and a non - metal (chlorine, \(Cl\)). Metals tend to lose electrons and non - metals tend to gain electrons. Calcium loses 2 electrons (\(Ca^{2+}\)) and each chlorine atom gains 1 electron (\(Cl^{-}\)). The electrostatic attraction between \(Ca^{2+}\) and \(2Cl^{-}\) forms an ionic bond.
• Name: The naming of ionic compounds follows the rule of naming the metal first and then the non - metal with an -ide suffix. So, for \(CaCl_{2}\), the metal is calcium and the non - metal is chlorine (changed to chloride), giving the name calcium chloride.

Answer:

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