To determine which element has ten protons and ten neutrons, we refer to the Periodic Table. Elements are organized by increasing Atomic Number, which indicates the number of protons in the nucleus of an atom.
The Atomic Number equals the number of protons for an element: Atomic Number = Number of Protons
When we check the Atomic Number, we see that Neon (Ne) is the element with ten protons. Therefore, Neon is the element we're looking for.
Protons are positively charged particles that define the identity of an element, while neutrons add to the atom's mass. With ten neutrons, the total mass number is 20, corresponding to Neon-20, the most common isotope of Neon.

Protons, Neutrons, and Electrons for Ions: youtu.be/HkQEDntUK0U
Rules:
Atomic Number = Number of Protons
Number of Protons = Number of Electrons (for a neutral element)
Mass Number = Number of Protons + Neutrons
