Question

what type of bond is formed between a metal and a nonmetal? * 5 points
covalent
ionic
metallic
what is the formula for calcium chloride * 5 points
cacl2
ca2cl
cacl

Explanation:

1. When a metal and a non - metal react, the metal loses electrons to form a cation and the non - metal gains those electrons to form an anion. The electrostatic attraction between the cation and anion results in an ionic bond. Covalent bonds form between non - metals sharing electrons, and metallic bonds are between metal atoms.
2. Calcium has a +2 charge (Ca²⁺) as it is in Group 2 of the periodic table and chlorine has a - 1 charge (Cl⁻) as it is in Group 17. To balance the charges, two chlorine atoms are needed for one calcium atom, so the formula is CaCl₂.

Answer:

1. B. Ionic
2. A. CaCl2
