To accurately represent an atom of a different element, the most effective way is:
**Increasing the number of protons in the nucleus.**
The identity of an element is determined by the number of protons it has in its nucleus. Changing the number of protons changes the element itself, while increasing electrons or changing neutrons affects the charge or isotope but not the elemental identity.
