Ans. 49 B) polar molecules
Exxplaination:- Polar molecules are those types of molecules in which there is an unequal sharing of electrons between the two atoms. and hence there is development of more positive charge on one side of the molecule and negative charge on the other side of molecule such a molecule formed is called as polar molecules.
Ans. 50 B) 20 neutrons
Explaination:- Mass number = number of protons + number of neutrons ,, protons number is equal to electrons (atomic number)

A covalent bond is a bond in which electrons are shared between atoms of elements
A covalent bond is a
bond in which electrons are shared between atoms of elements. A
covalent bond can be polar or nonpolar. In a nonpolar covalent
bond, the bond is between two identical atoms and the electrons are
evenly shared between the atoms.In contrast, in a
polar covalent bond, the bond is between two nonidentical atoms and
the electrons are unevenly shared between the atoms. The uneven
sharing of electrons takes place because of the difference in the
electronegativity...

What is true about a pure covalent bond? a. The electrons are shared equally between the atoms in the bond. b. The electrons are transferred from one atom to the other in the bond. c.The electrons are shared unequally between atoms in the covalent bond. d.
