Question

Natalie observes these characteristics in the model of an atom.

(i) includes positive charge
(ii) contains electrons
(iii) explains the photoelectric effect
(iv) suggests the probable location of electrons

Which model is Natalie most likely examining?
Bohr model
Dalton’s model
plum pudding model
electron-cloud model

Answer 1

The answer is option D "electron-cloud model." A electron-cloud model includes: includes positive charge, contains electrons, explains the photoelectric effect, suggests the probable location of electrons. It was also invented by Erwin Schrödinger. 

Hope this helps!

Answer 2

Answer:

electron-cloud model

Explanation:

Dalton model said that atom is indivisible. Thompson’s model gave the plum and pudding model where the electrons are embedded like plums in a pudding of positive charge. Bohr’s atomic model proposed that electrons moved in definite orbits around the nucleus in an atom.  Schrondinger's electron-cloud model proposed that electrons are not definite particle but they exists as diffused cloud. The position of electron cannot be stated exactly but the probability of finding an electron in a 3 dimensional space can be given.
