Question

If an atom 'x' has mass number 23 and atomic number 11 . state the number of protons,electrons , neutrons

Answer 1

Answer:

Photosynthesis is the process by which plants use sunlight, water, and carbon dioxide to create oxygen and energy in the form of sugar.

Answer 2

The number of protons present in an atom is 11. The number of electrons present in an atom is 11. The number of neutrons present in the atom is 12. Therefore, the option (B) is correct.

Correct option is

B

11,11,12

(B) 11,11,12

Given - Mass number of atom = 23

Atomic number of atom = 11

As, no. of electrons in an atom is equal to an atomic number of the element.

So, number of electrons = 11

Secondly , number of protons are equal to number of electrons.

so, number of protons = 11

And number of neutrons = mass number - atomic number = 23−11 = 12

so, number of neutrons = 12

So , the atom contains 11 protons, 11 electrons, 12 neutrons.
