Question
An atom of lithium has 3 protons and 4 neutrons.Determine its mass number. 1347
Solution
The mass number of an atom is determined by the total number of protons and neutrons in its nucleus.
Step 1: Identify the number of protons in the lithium atom. In this case, it is 3.
Step 2: Identify the number of neutrons in the lithium atom. In this case, it is 4.
Step 3: Add the number of protons and neutrons together to find the mass number.
So, 3 (protons) + 4 (neutrons) = 7
Therefore, the mass number of this lithium atom is 7.
