Bohr’s atomic model (3pts) (A) proposes that electrons occupy specific energy levels (B) explains the emission spectra of hydrogen atoms (C) predicts the energy levels of multi-electron atoms (D) both A and B

Correct option: D (both A and B)

Explanation:

Key things of bohr's model is that electrons occupy fixed orbital and required fixed amount of energy and electron must be in specific orbital and have precise amount of energy for that orbit

Niels bohr proposed a hydrogen atom model  which explains the spectrum of hydrogen and he assumed that electron of hydrogen revolves around the nucleus in the circular orbit and bohr's model is valid only for single electron species.

statement of option A and B are correct

hence D is correct

"hydrogen bonding is the attraction of h atoms in the water molecule (slight + charge) to o atoms in a neighboring water molecule (slight - charge); it is a weak interatomic force. but it is still strong enough to the water molecules "stick" together."

the answer is 0.8m.
