Question

Decide which element probably forms a compound with chlorine that has a chemical formula most and least similar to the chemical formula of the compound formed by chlorine and beryllium.

Answer 1

Magnesium (Mg)

Step-by-step explanation:

The reation between beryllium (Be) and chlorine (Cl2):

`Be + Cl_2 \longrightarrow BeCl_2`

The elements that may form a compound with a similar formula of the BeCl2 are some of the other members of the Group II of the periodic table.

One example of this is the reaction of chlorine with magnesium:

`Mg + Cl_2 \longrightarrow MgCl_2`
