How Many Valence Electrons Does Lithium Have
How many valence electrons are in lithium? ۔
Lithium has only one valence electron on the second energy s.
(It has 3 electrons as a neutral atom ... 2 in S1 and 1 in S2).
(It also has a nucleus of 3 protons and 4 neutrons, atom m = 7))
Have you studied or are you studying the Lewis dot structure?
When you create this structure and you are working with the main group elements (usually the only column in the table that is numbered), just take the group number and this is the number of valence electrons. For example, hydrogen is in the first column and has one valence electron, and oxygen is in the sixth group and has six valence electrons, and carbon is in the fourth group which has four valence electrons. In Table ic below my source, the key elements of the group are those with Roman numerals and A above. Lithium is in the column like hydrogen. Lithium contains valence electrons. Help for example :)
Lithium is a group 1 (IA) element containing one valence electron.
