Question

Which of the following determine the chemical properties of an element?

A)​​​​​​Its protons

B)Its inner shell electrons

C)The size of its nucleus

D)Its valence electrons

Answer 1

D, valence electrons.

Step-by-step explanation:

Since the number of shells are dependent on the number of valence electrons, which determines the period of the element. Because each shell of an element holds a total of 8 valence electrons, there is a chemical association that is being made between the outer electrons and the atom.

Answer 2

The correct answer is D. Its valence electrons.

Step-by-step explanation:

The valence electrons are those that participate in reactions with other elements. The fewer valence electrons that an element has, the less stable it becomes; an element with a full valence electron shell does not frequently interact with other elements. In this way, the valence electrons determine the chemical properties of an element.
