Which of these statements about Bohr's model of the atom is incorrect ?
A) Electrons fill lower energy orbits first.
B) The greater the quantum number the higher the energy of an orbit.
C) Electrons occupy orbits with certain radii that correspond to discrete energies.
D) Elements with the same number of electrons in their outer orbit undergo similar chemical reactions.
E) Electrons in the innermost energy orbit are called valence electrons.

Question

Quizplus · Accepted Answer

Electrons in the innermost energy orbit are not called valence electrons. Valence electrons are the electrons in the outermost energy level of an atom, and they are responsible for bonding and chemical reactions.
