Step-2: We know that the atomic number of  selenium  is 34.So  selenium  has 34 protons and 34 electrons as the charge of electrons and protons are equal but opposite in nature.The charge of proton is +1 and the charge of electron is -1. Sulfuric acid is an acid because it has hydrogen ion.The formula for sulfuric acid is H₂SO₄.It is a strong acid. The periodic table is a chart that organizes elements by atomic structure. protons 95 . Electrons have a negative charge. the Americium is radiate element in the Actinium series 5f in the periodic table its atomic number is 95 so. :) As for neutrons, they are different because they have no charge. If a neutral atom has 2 protons, it must have 2 electrons. Step-1: To do electron configuration of m agnesium element, we have to know the atomic number of the   magnesium .The atomic number of magnesium element is 12.So  magnesium   has 12 electrons and 12 protons.
