Question:
If an atom has 5 protons, 7 neutrons and 5 electrons what is the mass number of the atom?
Expert Verified Solution:
For an atom with 5 protons, 7 neutrons, and 5 electrons:
Protons: 5
Neutrons: 7
The mass number is calculated as follows:
- Mass Number=Number of Protons+Number of Neutrons
- Mass Number=5+7=12
So, the mass number of this atom is 12.
Description: To determine the mass number of an atom, you need to add the number of protons and neutrons in the nucleus. The mass number represents the total number of these particles, which together define the atom’s overall mass.
