→About Relative Atomic Mass
===About Relative Atomic Mass===
: The '''relative atomic mass''' in [[gram]]s on the [[Periodic Table]] tells the [[mass]] of a [[mole]] of the [[element]].: A [[mole]] of the [[element]] is [[Avagadro Constant|6.02x10<sup>23</sup>]] [[atom]]s of that [[element]].
: Two [[atom]]s of the same [[element]] may have the same [[Atomic Number]] but a different [[Relative Atomic Mass]] depending on the number of [[neutron]]s in the [[nucleus]]. [[Element]]s with different '''mass numbers''' are called [[isotope]]s.
: The '''relative atomic mass''' is not affected by the number of [[electron]]s.
