How many electrons, protons, neutrons are contained in each atom?

A) gallium-69

B) fluorine-23

C) titanium-48

D) tantalum-181

The atomic number of a neutral atom is equal to the number of protons and the number of electrons of the atom. The atomic weight meanwhile is equal to the sum of the number of protons and number of neutrons. Hence

A. P-31, E - 31, N - 38

B. P = E = 9, N = 14

C. P = E = 22, N = 26

D. P = E = 73, N = 108
