they provide a positive charge for the element
Element with 12 protrons is magnesium, as the number of protons determines the element's identity on the periodic table.
Sodium does.
The number of protons is the atomic number of the element.
Protons are components of the atomic nucleus of any chemical element.
Oxygen isotope 16
The number of protrons of whichever element you choose. Each element has an exact number of protrons.
Lithium is a metal element. There are 3 electrons in a single atom.
Magnesium is a metal element. There are 24 electrons in a single atom.
There are 67 protons in holmium. The atomic number of an element is the same as the number of protons.
Neon is a non metal element. There are 19 electrons in a single atom.
There are 26 protons and hence the atomic number is 26 and the element is iron.
Einsteinium has a proton number of 99, and can be found in the actinide group on the periodic table.
