Question

The electronic configuration of an element is found to be 2, 4. How many bonds
can atom of this element form in a compound?
a) 1 b) 2 c) 3 d) 4

Answer 1

Answer:

d) 4

Explanation:

It is the element which possess tetravalent property and thus form covalent compound of 4 bonds.

( the element is carbon )

Answer 2

If the electronic configuration of an element is found to be 2, 4, the atom of this element can form (d) 4 bonds.

• Atoms form chemical bonds with other atoms to attain a stable electronic configuration.
• The elements that have 8 electrons in their outermost shell have a complete octet of electrons and are stable.
• An element with configurations 2, 4 has 4 electrons in its outermost shell. It needs four more electrons to attain stability.
• This can be done by sharing electrons with atoms of the same element or different elements by forming covalent bonds.
