How many protons, neutrons, and electrons are found in an isotope of the following: Isotope
Atomic
Number
Mass
Number
Number of
protons
Number of
neutrons
Number of
electrons
195
78
78 protons, 78 neutrons, 78 electrons
117 protons, 195 neutrons, 78 electrons
78 protons, 195 neutrons, 78 electrons
78 protons, 117 neutrons, 78

there are 92 protons and 92 electrons therefore, 238-92=146(neutrons)

atomic number 9, mass number 18, and change - 1

Explanation:
