What is the mass number of neon? What is the maximum number of electrons that an atomic orbital can contain? Which is the noble gas notation for chlorine? What is the orbital diagram for oxygen? What is the electron configuration for argon?
What is the most common isotope of argon? Isotopes Explained: Elements are classified by the number of protons in the nucleus of the atom. However, there is no set rule for how many neutrons can be in the atom's nucleus. Because this number can vary, we classify the different, naturally...

Valency is the combining capacity of the elements to form compounds. During the formation of the molecules of the compounds, atoms combine in certain fixed proportions. Visit BYJUS to learn more about it.
The total number of protons and neutrons added together is called the relative atomic mass. Hydrogen has a relative atomic mass of 1, while helium's relative atomic mass is 4 (because there are two protons and two neutrons inside). In other words, an atom of helium is four times heavier...
