Question
An atom of boron (B) has 5 protons and 6 neutrons. What is its mass number?A.5B.6C.11D.16SUBMITarrow_backPREVIOUS
Solution
The mass number of an atom is calculated by adding the number of protons and neutrons. In this case, boron has 5 protons and 6 neutrons.
So, 5 (protons) + 6 (neutrons) = 11
Therefore, the mass number of a boron atom is 11. So, the answer is C.11.
