According the lewis dot structure shown here, how many valence electrons does chlorine have? a. Sulfuric acid is an acid because it has hydrogen ion.The formula for sulfuric acid is H₂SO₄.It is a strong acid. That gives a total of 5 electrons, so neutral phosphorus atoms have 5 valence electrons. Active 2 years, 9 months ago. Choose the appropriate number of atoms to make the bond. 6. 0 0. Valence electrons are the number of electrons present in the outermost shell of an atom. Chemistry. Sodium hydroxide is a base because it has hydroxide ion.The chemical formula for sodium hydroxide is NaOH.It is a strong base. Valence electrons are those electrons which are present in the outermost shell of an atom. How many valence electrons does one chlorine (Cl) atom have? It can acquire a stable configuration (2, 8, 8) of the nearest inert gas (Ar) by sharing one electron with another chlorine atom. When two chlorine atoms approach each other, at a certain distance between the nuclei, they share their valence electrons and form a shared pair of electrons. How many floors does St. Chlorine has 7 valence electrons; plus 6 for Oxygen, times 3; and this up here means we have another valence electron for a total of 26 valence electrons. Magnesium atoms have 12 protons. The 3d orbital has lower energy--it fills before the 4s because of electron repulsion energies.
