Answer:
It is a sigma bond
Explanation:
Chlorine has an electronic configuration of 1s2 2s2 2p6 3s2 3p5. This means that the outermost n=3 level has seven electrons. Hence one more electron is needed for the octet of outermost electrons to be achieved. As a result of this, chlorine enters into covalent bonding with another chlorine atom to form Cl2.
The outermost 3p electrons of the two chlorine atoms are now shared to form a p-p sigma bond (a single bond). Hence, the Cl2 molecule contains a sigma(single) bond between two chlorine atoms. Hence the answer written above.
All given elements belong to second period of periodic table. And we know that going from left to right along the period the number of shells (Principle Quantum Number) remains constant and the number of protons (atomic number) increases, due to this increase in nuclear charge the valence electrons are more attracted towards the nucleus resulting in decreasing the atomic radii, Hence, the atomic radii from larger to smaller radii are as ,
