(a) Number of electrons in the atom is

(d) Atomic number of this element is
(e) Protons and neutrons are located in​

Answer 1

Answer:

A. The number of electrons in a neutral atom is equal to the number of protons. The mass number of the atom (M) is equal to the sum of the number of protons and neutrons in the nucleus.

D. The atomic number is the number of protons in the nucleus of an atom. The number of protons define the identity of an element (i.e., an element with 6 protons is a carbon atom

E. The protons and neutrons that make up the nucleus are approximately the same mass (the proton is slightly less) and have the same angular momentum, or spin

Answer 2

Answer:

(a) Number of electrons in the atom is the number of atoms located at their outermost shells.

(d) Atomic number of that element is the total number of electrons present in their outermost shells.

(e) Protons and neutrons are located in the nucleus
