Can atoms of the same element differ in the number?

Answer 1

Isotopes of the same elements can differ in neutron number

Multiple isotopes can exist within an atom; these isotopes share the same atomic number and electron number, but differ in their neutron number.

The isotopes of carbon, for instance, are carbon 12, 13, and 14.

Six electrons, six protons, and six neutrons make up carbon 12.

Nine neutrons, six protons, and six electrons make up carbon 13.

There are six electrons, six protons, and eight neutrons in carbon 14. Good luck!

Answer 2

No, different elements can have different isotopes with the same proton count but different neutron counts; otherwise, all atoms of the same element have the same number of protons in their nucleus, defining their elemental identity.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
