Question

the mass number and atomic numbers of an element X is 33 and 15 respectively. what is difference between the number of proton and neutron of the element?​

Answer 1

difference between the number of proton and neutron of element is = 3

Explanation:( A= atomic mass)

n + p = A

A - p = n

33 - 15 = 18

n = 18

p=15

n - p = 3

Answer 2

Answer:

Difference between the number of neutrons and protons of the element is 3.

Explanation:

Atomic number:

• Each element has a specific number of protons in its atoms. In actuality, the number of protons in an atom specifies which atom we're looking at (for example, all atoms with six protons are carbon atoms); the atomic number is the number of protons in an atom.

Mass number:

• The mass number of an element is determined by the number of protons and neutrons added together: mass number = protons + neutrons.
• Simply subtract the number of protons, or atomic number, from the mass number to determine how many neutrons an atom has.

Result:

Given, Mass number of element X = 33

Atomic number of element = 15

∴ Number of protons = 15

Number of neutrons = Mass number - Number of protons

                                  = 33 - 15 = 18

∴Difference between number of neutrons and protons is = 18 - 15 = 3
