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

b..

is the correct one

explanation:

covalent bonds form as valence electrons are shared between two atoms. lewis structures and structural formulas are common ways of showing the covalent bonding in organic molecules. formal charge describes the changes in the number of valence electrons as an atom becomes bonded into a molecule.
