Question

which of the following elements does not lose an electron easily?
(a) Na
(b) F
(c) Mg
(d) Al​

Answer 1

Answer:

Flourine is the most electronegative element .... hence it does not lose an electron easily....  It has 7 electrons in the outer most orbit..  It is the smallest size atom too.  So it does not lose electrons easily.

Na , has one valence electron, Magnesium has 2, and Aluminum has 3.. These are  metals which lose electrons easily..

Explanation:

Answer 2

Answer:

b) F

Explanation:

Among the given elements fluorine(F)can not lose electrons easily because of its high electron affinity, high nuclear charge and high electronegativity.
