How does Sodium turns into another element? By the Nuclear Fusion?

If an atom loses or gains a proton, it becomes a new element. For example, if a sodium atom loses a proton, it would become a negative ion of neon. ... In nuclear reactions, like nuclear fusion, the electrons play minor roles and it is the nucleons that interact to create new elements

the old alchemists made significant contributions to science even though there starting premises were off a bit. their conclusions after failure would steer them into better directions for investigation. science is no more than close observation and the initial mistakes result in rethinking and retrying experiments.

the formula mass of a molecule or a compound is the sum of the atomic weights of the atoms in its empirical formula

(that's what i know about formula mass)
