Answer 1

An atom's atomic mass represents the area where an electron is most likely to be found. When an atom gains or loses an electron, it becomes an ion. The combined number of protons and neutrons is the mass number of an element. The atomic mass is the average mass number of the isotopes of an element.

Step-by-step explanation:

1. a. An atomic mass represents the area in an atom where an electron is most likely to be found.
2. b. An atom that gains or loses an electron and has an electric charge is called an ion.
3. c. The combined number of protons and neutrons is the mass number of an element.
4. d. The atomic mass is the average of the mass numbers of the isotopes of an element.
