Question

in the formation of compound atom a donates one electron each to two atoms of p if the atomic number of A and B are 12 and 9 respectively show the electron dot structure of a and b and the formation of compound name the bond formed in compounds List three properties of compounds formed by bonding​

Answer 1

In the compound of compound, atom A donates one electron to two atoms of B if the atomic number of A and B are 12 and 9 respectively, then -

• The compound formed by the two atoms A and B is $AB_{2}$.

• The bond required to form the compound is ionic bond.

• PROPERTIES OF THE COMPOUND:

1. The compound is ionic in nature i.e. the compound can be dissociated into ions $A^{2+}$ and $B^{-}$ in its aqueous solution.
2. The boiling point and melting point of this compound is very high due to the ionic bonding.
3. This compound has higher enthalpies of fusion and vapourisation that the covalent compounds.

• The electron dot structure is shown below.
