Answer 1: B (As explained below)
Covalent bonds involve sharing of electrons. These shared electrons are called shared pairs or boning pairs.
Answer 2: A (As explained below)
When compounds are formed by complete transfer of valence electrons, the bonds formed are ionic in nature.
Answer 3: D (As explained below)
The oxygen atoms in a water molecule are electronegative due to the lone pair of electrons they have and so they can bond with the adjacent hydrogen atoms forming polar covalent bonds.
Answer 4: O (As explained below)
This is so because the electrons in the covalent bond are equally shared in Non-polar Covalent bonds.
Answer 5: C (As explained below)
When an electron leaves an atom there is a deficit of negative charge which automatically implies a positive charge on the resulting ion.
Answer 6: G (As explained below)
The oxygen atoms in a water molecule have a lone pair of electrons and so they can bond with the adjacent hydrogen atoms. This type of bonding is called hydrogen bonding.
Answer 7: E (As explained below)
An anion has a negative charge. It's easy to recollect which ion has which charge between anion and cation, if we simply recollect that A.N.ION is A Negative Ion.
