Why Does Sodium Only Have One Valence Electron?

Why Does Sodium Only Have One Valence Electron? The highest energy 3s orbital contains one electron, therefore, neutral sodium atoms have one valence electron. How many valence electrons does sodium have? – Means sodium has one valence electron which is present in 3s orbital. Why does sodium only have 1 valence electron? A: An atom

What Are 4 Elements That Have 7 Valence Electrons?

What Are 4 Elements That Have 7 Valence Electrons? The elements in this family are fluorine, chlorine, bromine, iodine, and astatine. Halogens have 7 valence electrons, which explains why they are the most active non-metals. They are never found free in nature. What elements has 7 valence electrons? Any element in the halogen group will

What Is The Mass Number Of An Atom With 17 Protons 17 Electrons And 18 Neutrons?

What Is The Mass Number Of An Atom With 17 Protons 17 Electrons And 18 Neutrons? An element with 17 protons will always be chlorine. However an element’s mass numbers can vary, which means that it can have different numbers of neutrons. So although chlorine has a mass number of 35 which means it has
