Answer: There is a single covalent bond in a chlorine molecule.
Explanation: The chlorine molecule is represented as Cl−Cl, i.e. C
l2. Between the chlorine atoms, 2 electrons overlap to form a region of high electron density to which the positively charged chlorine nuclei are attracted, such that internuclear repulsion is negated and a net attractive force results. Because the bonding electrons are shared between the nuclei, we conceive that each atom has 8 valence electrons.
Of course, on reaction with sodium, the sodium reduces the chlorine molecule to give 2×Cl−. The resultant bond between Na+ and Cl−is ionic and a non-molecular substance results.

Usually the beta particles are electrons with negative charge. And positrons are with positive charge. So they have the same mass and different charges. The answer is (3).
False , they form water or ice crystals
Checking if it is balanced:
C
3 3
H
8 4*2 = 8
O
8 3*2 + 4 = 6 + 4 = 10
8 10
Only O is not balanced.
So O is violating the law. Option C.
