13. Composition of the nuclei of two atomic species and
given as under
X Y
Protons = 6 6
Neutrons=6 8

Give the mass numbers of X & Y.
What is the relation between the two species?​

mass no:

Mass number of X = No. of protons + No. of neutrons

= 6 + 6 = 12

Mass number of Y = No. of protons + No. of neutrons

= 6 + 8 = 14.

relation:

The 2 atomic species X and Y have  same atomic number and a different mass number.therefore , they are isotopes.

hope it helps plz mark as brainliest

answer:

Composition of the nuclei of two atomic species, X and Y are given as under X Y Protons = 6 6 Neutrons = 6 8Give the mass numbers of X and Y. ... These two atomic species X and Y have the same atomic number, but different mass numbers. Hence, they are isotopes.

Explanation:

Composition of the nuclei of two atomic species, X and Y are given as under X Y Protons = 6 6 Neutrons = 6 8Give the mass numbers of X and Y. ... These two atomic species X and Y have the same atomic number, but different mass numbers. Hence, they are isotopes.

Explanation:

Mass number of X=8+8=16

Mass number of Y=8+10=18

These two.are isotopes of oxygen

Explanation:

Mass no. of any atom = no. of protons+no. of neutrons i.e. total no. of nucleons.

Mass no. of X=6 protons+6 neutrons=12

Mass no. of Y=6 proton+8 neutrons=14

The two atoms have the same Atomic No. (Z) i.e. same no. of protons, hence also same no. of electrons.

Hence, X and Y are the atoms of the same element.

X and Y are ISOTOPES of the same element i.e. atoms with the same atomic no. but different mass nos. due to difference in no. of neutrons.

This does affect physical and radioactive properties of the atom, but not the chemical properties (as chemical properties depend on electrons, which are present in same no. in isotopes.)

Hope thia helps!

mass no. of x = 12

mass no. of x = 14

Mass No. of X = 12,

Mass No. of Y = 14.

Explanation:

Mass no. = No. of protons +No. of neutrons

So, Mass no. of X=6+6

So, Mass no. of X=12

Also, Mass no. of Y=6+8

So, Mass no. of Y = 14

Now, as the no. of protons are equal in both elements and the no. of neutrons are different;

So, these elements are isotopes to each other.
