Question

Given an element X. Find out the following:

a) Number of electrons

b) Number of neutrons

c) Mass number of X

d) Identify the element

e) electronic configuration of element X​

Answer 1

BUT GIVE SOME KNOWLEDGE ABOUT ELEMENT X

THEN ONLY WE CAN FIND THOSE REQUIRED VALUES

Answer 2

Answer: 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.
