Question

an atom X has a mass number 23 and atomic number 11 find its electrons protons and neutrons also name the element
​

Answer 1

Answer:

11,11,12

Explanation:

Given - Mass number of atom = 23

The atomic number of atom = 11

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

So, the number of electrons = 11

Secondly, the number of protons is equal to the 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.

The name of the element is sodium.
