In drawing Lewis structure, a single line (single bond) between two elements represents
A shared pair of electrons
An octet of electrons
An unshared pair of electrons
Transfer of an electron
The basic principle in the formation of electrovalent bond is
the sharing of electrons which leads to the sharing of atomic orbitals
the transfer of electrons which leads to the formation of ions of opposite charges.
the formation of positive ions which are bonded together in the negative charge of electron cloud.

Which of the following statements regarding chemical bonding is correct?
All atoms must attain octet configuration after bond formation
Bond can only be formed between atoms of metals and atoms of non-metals
All chemical bonds are electrostatic in nature
The intermolecular forces must always be stronger than intramolecular forces.
A lone pair is defined as
A pair of bonding electrons
