An Atom with 11 Protons,12 Neutrons,and 10 Electrons Has an Atomic

Question

An atom with 11 protons,12 neutrons,and 10 electrons has an atomic mass of 21.

Accepted Answer

The atomic mass of an atom is equal to the sum of its protons and neutrons. In this case, the sum of protons and neutrons is 11+12=23, which is not equal to the given atomic mass of 21. Therefore, the statement is false.
