Question

Beryllium, Be, and chlorine, Ci, form a binary ionic compund with a one-to-two ration of beryllium ions to chloride ions. The formula for the compund is

A)Be2Cl
B)BeCl
C)BeCl2
D)Be2Cl2

Answer 1

Be2Cl because the number get switched

Answer 2

The correct answer is option C.

Step-by-step explanation:

Binary compounds are compounds which are made up of only two types of different elements ,forexample : HCl, NaCl etc

Beryllium, Be, and chlorine, Ci, form a binary ionic compound:

Ratio of beryllium to chlorine atom = 1 : 2

If there are x atoms of beryllium, then there 2 x atoms of chlorine atoms in the ionic compound:

`Be_xCl_(2x)=BeCl_2`

The formula for the compound is
`BeCl_2`
