Question

Which element has the maximum tendency to form covalent bonds in second period of periodic table

Answer 1

Answer:

carbon

Explanation:

Due to the property of tetravalency ,carbon can neither gain nor loose it's electrons to attain octet in its electronic configuration.Hence it tends to share it's electron to form covalent bonds.Moreover ,the question seeks the element in 2nd period which makes carbon the right choice.

Answer 2

The element has the maximum tendency to form covalent bonds in second period of periodic table

Explanation:

The element has the maximum tendency to form covalent bonds in second period of periodic table: that is carbon .

Carbon

Its symbol is C

Its atomic number 4

Its E.C=2,4

Its valency is =+4,-4

It forms maximum number of covalent bonds because of :

• Tetravalency
• Catenation

Tetravalency : It is the presence of 4 electrons in outer most shell of an atom which it can easily loose , gain or share .

Catenation : It is the tendency of an atom to combine with its own kind in order to form long chains that can be straight , branched or ring like .
