Solution:

Both statement are false

---> The number of neutrons can be determined by the number of electrons or protons and atomic mass number.

Knowledge booster:

1. Number of neutrons= Atomic mass number - Number of protons or electrons
2. As atomic mass number = Number of protons or electrons + Number of neutrons
3. Atomic number = Number of protons or electrons
