The element with a proton number of 15 is Phosphorus; P
The element with one proton per atom is hydrogen.
protons, no. of protons is equal to the atomic number of an element.
hydrogen
The only element that has one proton and no neutrons is a hydrogen atom.
Platinum
the proton number is 15
31 - 15 = 16 neutrons
Hydrogen ion is the only element that has no neutron and one proton. That is why it is basically a proton.
my fellow questioner, a proon is an element _____ Actually a prune is a dried plum. A proton is a subatomic particle, it is not an element. However, the element hydrogen does turn into a proton when ionized. So it's close.
The lightest element with only one proton is hydrogen.
The element with one proton per atom is hydrogen.
It has similar properties to the element with proton number 20, which is calcium.
The element with one proton per atom is hydrogen.
protons, no. of protons is equal to the atomic number of an element.
The element copper (Cu).
maybe proton
An element with 1 proton is hydrogen. An Isotope called Tritium has one Proton and two Neutrons. Hope this helps.
