Question

13. Assertion (A) : Carbon has a strong tendency to either lose or gain
electrons to attain noble gas configuration.
Reason (R): Carbon has four electrons in its outermost shell and has
the tendency to share electrons with carbon or other
elements.
14. Assertion (A): At high temperatures, metal wires have a greater chance
of short circuiting.
Reason (R): Both resistance and resistivity of a material vary with
temperature.​

Answer 1
