Question

according to bohrs model of the atom, in which orbitals do electrons have the least energy?
outermost orbitals
middle orbitals
innermost orbitals
question 2
1 pts
where are valence electrons located?
closest to the nucleus
in both the inner and outer electron shells
inside the nucleus
in the outermost electron shell

Explanation:

Question 1

Bohr's atomic model states that electrons orbit the nucleus in energy levels (orbitals). The innermost orbitals are closest to the nucleus and have the lowest energy because electrons closer to the nucleus are more strongly attracted and have less energy than those in outer orbitals.

Valence electrons are the electrons in the outermost electron shell (valence shell) of an atom. These electrons are involved in chemical bonding. Electrons closest to the nucleus are inner - shell electrons, electrons can't be inside the nucleus, and valence electrons are only in the outermost shell, not both inner and outer.

Answer:

innermost orbitals
