Molybdenum has an atomic number of 42. several common isotopes exist, with mass numbers from 92-100. therefore, which of the following can be true? a) molybdenum atoms can have between 50 and 58 neutrons.
b) molybdenum atoms can have between 50 and 58 protons.
c) molybdenum atoms can have between 50 and 58 electrons.
d) isotopes of molybdenum have different numbers of electrons.

The true statement is that Molybdenum atoms can have between 50 and 58 neutrons

Explanation:

Step by step

I) Recall that Atomic number = Number of protons

So, Molybdenum with atomic number of 42 = 42 Protrons

II) Also, recall that Mass number = Number of protons + number of neutrons;

So, if Molybdenum mass number is 92,

then Neutrons = 92 - 42 = 50

III) If Mass number is 100,

then Neutrons = 100 - 42 = 58

So, Molybdenum atoms can have between 50 and 58 neutrons

answer: d. load

a river's load refers to the natural phenomena in which the sediments, rocks   stones, boulders and other deposits are removed and picked from the bottom bed of the river due to the abrasion resulted by the high speed water current.
