What are the differences between elements on an atomic level?
Flexi Says:
Each type of atom is called an element. Elements are characterized by the number of protons in the nucleus, which also affects the number of neutrons and electrons in the atom. Each element is unique and has its own properties. There are 118 elements known so far. Isotopes are atoms that have the same number atomic number, but different mass numbers due to a change in the number of neutrons. For example, the three isotopes of carbon element can be referred to as carbon-12, carbon-13, and carbon-14
