Question

identify bohrs model of the atom. his model describes the reactivity of an element based on its number of valence electrons.
a
atom
b
c
nucleus
cloud of electrons
d
a. a
b. b
c. c
d. d

Explanation:

Bohr's model of the atom depicts electrons orbiting the nucleus in defined circular paths or shells. Option D shows electrons in distinct circular orbits around the nucleus, which aligns with Bohr's model. Option A is too simplistic (not showing electrons or nucleus details relevant to Bohr's model). Option B is Thomson's plum - pudding model (with electrons embedded in a positive 'pudding'). Option C is the electron - cloud (quantum mechanical) model.

Answer:

D. D
