What are the number of protons, electrons, and neutrons in one atom of titanium?.
Olin [163]

Answer:

Protons: 22

Neutrons: 26
Electrons: 22

Explanation:

Titanium's atomic number is 22, meaning that the number of protons it has in its nucleus is also 22. # of electrons = # of protons, so the number of electrons is also 22. Titanium has an atomic mass of 47.867, but we can round up to 48. To find the atomic mass, we add up number of protons and neutrons. We know the number of protons as 22, so we subtract 22 from 48 and get a number of 26. Thus, the number of neutrons is 26.
