Question

Strontium has a atomic number of 38 and a mass number of 88 how many neutrons are in one atom

Answer 1

Atomic number=number of protons (and electrons, but that doesn't matter in this answer)
Atomic mass=number of protons+number of neutrons
Atomic mass=atomic number+number of neutrons
Atomic mass-atomic number=number of neutrons
88-38=number of neutrons
number of neutrons=50

Answer 2

Answer:

50 is correct. Just took the test.
