Question

Excluding the noble gas group, how does the number of valence electrons in an element influence its chemical reactivity? O A. Elements with the lowest and highest numbers of valence electrons are the most reactive, B. As the number of valence electrons increases, the chemical stability of the elements decreases. C. Elements with the lowest and highest numbers of valence electrons are the least reactive. O D. As the number of valence electrons increases, the chemical stability of the elements also increases.​

Answer 1

Answer:

A

Explanation: a p e x i took the exam got it right

Answer 2

The relation can be described as:

A. Elements with the lowest and highest numbers of valence electrons are the most reactive.

Elements with lowest or highest valence electrons:

Valence electrons can be described as the electrons in the outermost shell. The elements having the least valence electrons such as Helium which has stable electronic configuration or Chlorine which has the highest valence electrons that are 7. These can react easily with the elements having electrons according to reactivity.

Example: Chlroine reacts more easily with elements of group 1.

Thus, option A is correct.
