Elements are scheduled in Periodic table, ordered by their atomic number.
Other example, krypton is a chemical element with symbol Kr and atomic number 36.
Krypton has 36 electron and 36. It is noble gas (group 18).
Noble gases are in group 18: helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe) and radon (Rn). They have very low chemical reactivity.
