Question

Two atoms have the same number of protons but different numbers of neutrons. What can you conclude about these two atoms?

Answer 1

These two atoms are isotopes

Let Z be Atomic no.

Let p be no. of protons

Let A be no. of mass no.

Let n be no. of neutrons

Z=p

Therefore,it has same atomic no.

A=p+n

Therefore,it has same mass no.

And,the definition of isotopes say that,the atoms of the same element having same atomic number [Z] but different mass numbers[A] are called isotopes.

Overall,we can conclude that these two atoms are isotopes.

Hope it helps........
