A) 49 protons correspond to In.

B) Co has 27 protons.

C) Ta has 73 protons.

D) Atoms have the same number of protons and electrons, so there are 49 electrons.

E) Barium has 56 protons.

F) Barium normally has 56 electrons, but since the charge is +2, 2 electrons were lost, making the answer 54.

G) The atomic mass is protons + neutrons, so since there are 49 protons, there are 115-49=66 neutrons.

H) Same logic as G, answer is 104.
