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:

the answer is learned

the positions which points up in upward carbon and down in downward carbon are axial

and vice versa holds true for equatorial positions

so the correct answer with labelled diagram will be
