each atom of protium has one proton, no neutrons, and one electron. Each atom of deuterium has one proton, two neutrons, and one electron. Are these the same or different elements? Why? help asap you guys!

Respuesta :

znk

Answer:

These are the same element.  

Explanation:

H = 1p + 1e

D = 1p + 1e + 1n

Protium (H) and deuterium (D) are isotopes of the same element (H).

If two atoms have the same number of protons, they are the same element.

If they have the same number of protons but different numbers of neutrons, they are isotopes.
