WebMay 7, 2024 · This electron configuration is written as 1 s2 2 s1. The next element is beryllium, with Z = 4 and four electrons. We fill both the 1 s and 2 s orbitals to achieve a 1 s2 2 s2 electron configuration: When we reach boron, with Z = 5 and five electrons, we must place the fifth electron in one of the 2 p orbitals. Web(a) three elements that have a single electron in their outermost shells. (b) two elements that have two electrons in their outermost shells. (c) three elements with filled outermost shells.
WebValence electrons are the electrons in the outermost shell, or energy level, of an atom. For example, oxygen has six valence electrons, two in the 2s subshell and four in the 2p subshell. We can write the configuration of oxygen's valence electrons as 2s²2p⁴. Created by Sal Khan. Sort by:
WebJun 8, 2024 · Figure 2.5. 1: Bohr diagrams: Bohr diagrams indicate how many electrons fill each principal shell. Group 18 elements (helium, neon, and argon are shown) have a full outer, or valence, shell. A full valence shell is the most stable electron configuration.
