Question

The table compares some characteristics of two atoms.

Answer 1

The number of protons in X would be 6 while that of Y would also be 6. Thus, the two atoms would be isotopes of the same element.

Atomic properties of atoms

The mass number of an atom is the sum of protons and neutrons present in the atom.

For X with mass number 12 and neutron number 6, the number of protons would be:

                                 12 - 6 = 6 protons

For Y with mass number 13 and neutron number 7, the number of protons would be:

                                     13 - 7 = 6 protons.

Thus, both atoms have the same number of protons, meaning that they are likely isotopes of the same element.
