The term valence electrons needs to be explained and the number of valence electrons of magnesium atom needs to be determined. Magnesium can donate its two valence electrons forming the magnesium ion with +2 charge. Electrons of outer most orbital of an atom refer to as valence electron. The outermost orbital of magnesium is 3s. Sulfuric acid is an acid because it has hydrogen ion.The formula for sulfuric acid is H₂SO₄.It is a strong acid. Subscribe to bartleby learn! Add caption Step-1: First, find the atomic number of selenium from periodic table. Step-3: Now write the electron configuration of potassium . © copyright 2003-2020 Study.com. The valence or valency refers to the ability of the atom of a chemical element to bond with other atoms to form other substances by determining the number of electrons in its outermost atomic orbital. 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.
