Question

An atom that has an atomic number of 38 and a mass number of 88 is an isotope of an atom that has An atom that has an atomic number of 38 and a mass number of 88 is an isotope of an atom that has an atomic number of a. 38 and a mass number of 86. b. 50 neutrons and 38 protons. c. an atomic number of 39 and a mass number of 88. d. 50 protons and 38 neutrons.

Answer 1

Answer: Option b. 50 neutrons and 38 protons.

Step-by-step explanation:

Atomic number = proton number = 38

Mass number = proton number + Neutron

Mass number = 88

Proton = 38

Neutron number =?

Neutron number = Mass number — proton number

Neutron number = 88 —38 = 50
