In ionic bonds electrons are transferred from one species to another and the electrostatic attraction between oppositely charged ions gives rise to the ionic bond.
covalent bonds are when electrons are shared between 2 atoms.
the electronegativity difference between the atoms taking part in the bond will decide if its an ionic bond or covalent bond.
if the electronegativity difference is very large then ionic bond is formed. if the electronegativity difference is very low then covalent bond is formed
the electronegativity difference between H and S is very small therefore they form a covalent bond by sharing their electrons
correct answer is
2) electrons are shared to form a covalent bond
example calculation for a.)
N = 39 - P
N = 39 - 19
<u>N = 20</u>
<u>P = 19</u>
