Hello, hi students, let me explain you the question.
00:02
Here, two atoms.
00:04
So these two atoms that are different isotopes.
00:11
So these two atoms are different isotopes of same element of same element.
00:19
So they must have same element.
00:23
They have.
00:24
So means they have same number of protons and same number of neutrons, same number of protons, same number of protons, different number of protons different number of neutrons different number of protons but the same number of neutrons so like this so many options they have given four options so among the four options we must select one option so first of all i want to tell you what are isotopes so isotopes these are the atoms of same element so these are the atoms of same element that means same element same element same atom here.
01:03
So means it having the same atomic number.
01:08
So it having the same atomic number but differ in their mass numbers.
01:15
But differ in their mass numbers.
01:18
So usually the mass number it is represented by means of a...
