Magnesium has an atomic number of 12, so there are 12 protons in any atom of this element. The number of protons do not change if it is an isotope of an element.
What is the name of protons in the atoms of an element?
Protons are protons, no matter what element they are in.
What is its nuclide symbol of An element has 12 protons and 13 neutrons?
The nuclide symbol for an element is represented as [ \text{A}{\text{Z}}^{\text{Element}} ], where A is the mass number (protons + neutrons) and Z is the atomic number (number of protons). For an element with 12 protons and 13 neutrons, the mass number (A) would be 25 (12 + 13) and the atomic number (Z) would be 12. Thus, the nuclide symbol is [ \text{^{25}{12}\text{Mg}} ], indicating it is magnesium.
How many neutrons protons electrons in sulfur-25?
Sulfur-25 has 16 protons and 9 neutrons. Since the element is electrically neutral, it also has 16 electrons.
What element has 12 protons 13 neutrons and 15 nucleons?
nucleons equal for protons and neutron total. so it should be 25 neucleons.
