The quantum model suggests that electrons
a. occupy no particular space
b. surround the protons
c. occupy specific locations around the nucleus
d. are in probable cloud locations

The correct answer is (d), electrons are in probable cloud location.

An atom is made up of three fundamental particles, electron, proton and neutron. Proton and neutron are located in the nucleus, while the electrons orbit the nucleus in relative large orbit, however the exact position of the electron in the shall is highly unpredictable, therefore they are assumed to be in probable cloud location where the probability of finding an electron is very high.

the small 0.38-kg slider is known to move from position a to position b along the vertical-plane slot. determine (a) the work done on the body by its weight and (b) the work done on the body by the spring. the distance r = 0.70 m, the spring modulus k = 154 n/m, and the unstretched length of the spring is 0.53 m
