Answer 1

Step-by-step explanation:

The number of protons in an atom is the atomic number.

Mass number is the number of protons plus neutrons in an atom.

Mass number = number of protons + number of neutrons

Atomic number = number of protons

Atomic number gives the symbol of the element

Number Number Atomic Mass Symbol

Protons neutrons Number Number

A 7 B 15 C

D E 26 56 F

A, number of protons = B

Mass number = protons + neutrons

15 = protons + 7

Protons = 15 - 7 = 8

Atomic number 8 is for oxygen = C

Atomic number = number of protons = D = 26

Number of neutrons ;

E = Neutrons = mass number - protons = 56 - 26 = 30

Atomic number 26 is for Iron = F
