Question

An element has an atomic mass number of 16 and an atomic number of 7.

The element has
protons and
neutrons.

Answer 1

• 9 neutrons and 7 protons

Step-by-step explanation:

Since the mass number of the element is 16 and atomic number is 7.

Mass number = No. of protons + No. of neutrons.

Also atomic number is equal to Number of the protons. so number of protons is 7

Now, Mass number = 7 + No. of neutrons.

16 = 7 + No. of neutrons

16 - 7 = No. of neutrons

9 = No. of neutrons.

Hence The element has 9 neutrons and 7 protons.
