Chemistry Question on Classification of elements & periodicity in properties
Which of the following is the most electropositive element?
A
Lithium
B
Boron
C
Carbon
D
Nitrogen
Answer
Lithium
Explanation
Solution
Electropositive nature decreases as we move across a period where as it increases down a group. Hence, Lithium will have more electropositive nature than any other element as it has largest size and easily donates electrons due to less effect of nuclear charge on valence electron among given atomic numbers.
