Manganese, the 25th element, has 25 protons.
Each element has a unique number of protons. If another atom has the same number of protons as that element, it is the same element.
Radon (Rn) has the most protons of any element in Group 0 (18) with 86 protons. However, if or when Ununoctium is officially confirmed, that will become the element with most protons in that family, with 118 protons.
Experimentally, I'm not sure, but I know you can look at your periodic chart, the large number over the symbol of each element is teh number of protons in that element.
The element platinum (Pt) has 78 protons in the atomic nucleus.
This element is tin; for the natural isotopes the number of neutrons is between 62 and 76.
Because the atomic number is 62, the element Samarium has 62 electrons and 62 protons. Since the number of neutrons is calculated by subtracting the atomic number from the atomic mass, and Samarium's atomic mass is 150, it has 88 neutrons.
12. the atomic number of an element is the number of protons in it's nucleus. The mass number is the number of protons+neutrons. Therefore the element has (32-20)12 protons.
Protons are protons, no matter what element they are in.
Each chemical element has a specific number of protons; the number of protons is equal to atomic number of the element.
what element contains 16 protons? what element contains 10 protons?
Manganese, the 25th element, has 25 protons.
All atoms of the same element have the same number of protons. Atoms of different elements have different numbers of protons. The number of protons determines the element.
The element mercury has 80 protons.
Each element has a unique number of protons. If another atom has the same number of protons as that element, it is the same element.
Radon (Rn) has the most protons of any element in Group 0 (18) with 86 protons. However, if or when Ununoctium is officially confirmed, that will become the element with most protons in that family, with 118 protons.
No, Mg has 12 protons. The Element with 23 protons has the symbol V.
