Holmium: The number of protons per nucleus of an atom is the same as its atomic number.
Holmium has 67 protons. Symbol: Ho
Holmium
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.
Calcium: The identity of an element is determined by how many protons each atom of the element has, and calcium is the name of the element with 20 protons per atom.
There are 67 protons in holmium. The atomic number of an element is the same as the number of protons.
Protons are protons, no matter what element they are in.
67 protons, 67 electrons and 98 neutrons
There are 67 Protons, 67 Neutrons, and 67 Electrons. The Protons and Neutrons are in the center, While The Electrons revolve on the outside.
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.
The 34 protons means that this is the element that has an atomic number of 34, which is selenium. The mass number for the isotope given is 67, which is the sum of the protons and neutrons. Mass number is not the same as atomic mass. Atomic mass is the total mass of the protons, neutrons, and electrons in an atom.
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.
