Nettet13. aug. 2024 · (a) Mg is in Group 2A and has two valence electrons. It achieves octet by losing two electrons to form Mg 2+ cation. Losing only one electron to form Mg + does not make an octet, hence, Mg + is not likely to form. Exercise 3.2. 2 Which of these ions is not likely to form? S 3− N 3− Answer Lewis Diagrams
NettetNitrogen is a group 15 element and so has 5 valence electrons, while group 16 oxygen has 6 valence electrons. There are two oxygen atoms, so the total amount of valence electrons in our diagram is: 5(1) + 6(2) = 17 electrons. Our diagram should have 17 electrons in total.

NettetOverview Electron configuration. The electrons that determine valence – how an atom reacts chemically – are those with the highest energy.. For a main-group element, the valence electrons are defined as those electrons residing in the electronic shell of highest principal quantum number n. Thus, the number of valence electrons that it …
NettetThe valence electrons in an oxygen atom (box) are attracted to the nucleus by a positive charge nearly double, 1s^2-1box,2s^2-1box,2p^3-3boxes, that of boron. Therefore, the electrons in oxygen are held closer to the nucleus, giving it a smaller radius.
