PHY 104 Atomic Structures Objective Question

Question

What is the primary role of electrons in the outermost shell (valence electrons) of an atom?
Options
A To provide structural stability to the nucleus.
B To determine the atom's chemical properties and how it behaves as a conductor.
Correct Answer
C To absorb all incident radiation and prevent atomic excitation.
D To always remain in the ground state without energy exchange.
Correct Answer

Option B is the correct answer.

Detailed Explanation

The text states: 'The electrons in the outermost shell determine the chemical properties of the atom. Electrons in the outer shells (valence electrons) have higher energy and determine how atoms behave chemically and as a conductor.'

Hint

Consider which part of the atom is most involved in bonding and reactions.
