WebQ: Why does sodium give up an electron? A: An atom of a group 1 element such as sodium has just one valence electron.It is “eager” to give up this electron in order to have a full outer energy level, because this will give it the most stable arrangement of electrons.You can see how this happens in the animation at the following URL and in … Web14 feb. 2024 · For example – Chlorine belongs to group 7A in the periodic table, therefore, the number of valence electrons in chlorine is 7.

How many valence electrons do elements in group 10 have?

WebBohr diagrams indicate how many electrons fill each principal shell. Group 18 elements (helium, neon, and argon are shown in Figure 2) have a full outer, or valence, shell. A full valence shell is the most stable electron configuration. Answer: Yung nasa pic po, hope it helps :) 19. which configuration is possible in an excited state of electron? WebIf we were the actually break down the above diagram into groups rather than the blocks we have, it would show how exactly how many electrons each element has.
