Isotopes are different versions of a specific element.

Every atom/element is defined by its protons. So if it has 1 proton it's hydrogen no matter what, if it has 2 protons it's helium no matter what and so on. If you know the number of protons, you know the element.

You can change the number of neutrons in the nucleus and you'll get isotopes. Atoms that have different numbers of neutrons are isotopes of each other. It's important to understand that the element is the same but one is going to be a little bit heavier or lighter than another.

An isotope is an atom with a unique number of neutrons. Isotopes can differ from each other because of their number of neutrons.

Which word or group of words is represented by the word "period" in the term Periodic Table?

The correct answer is C : energy level.

As you can see in the image of the periodic table presented below, periods are the horizontal columns of the periodic table.
Elements belonging to the same period have the same electron shell, the same number of orbits filled with electrons.
Elements of the same period have similar chemical and physical characteristics
