WebIn making cations, electrons are first lost from the highest numbered shell, not necessarily the last subshell filled. For example, in going from the neutral Fe atom to the Fe 2+ ion, the Fe atom loses its two 4 s electrons first, not its 3 d electrons, despite the fact that the 3 d subshell is the last subshell being filled. Thus we have Chapter 9 Chemical Bonds 9.1 … 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.

WebThe first shell (of all atoms) has 1 subshell of s-orbitals containing 1 s orbital. This means that the first shell can hold 2 electrons. The second shell has 2 subshells: 1 s-orbital and 3 p-orbitals. This means that the second shell can hold 8 total electrons. Every orbital is a … So in the first shell there is only one subshell, the s orbital. It is called 1s. In … Valence electrons are the electrons in the outermost shell, or energy level, of an … WebJan 15, 2011 · Lithium has 3 electrons in every atom. The amount of protons in each atom is the same as the amount of electrons. The proton number is three so the electrons are …
WebAnswer (1 of 2): As you know, oxygen electrons occupy only two shells: the first and second ones. The first shell contains the 1s subshell, capable of holding 2 electrons. The second shell contains the 2s and 2p subshells, capable of holding 2 + 6 = 8 electrons. In oxygen, the first shell is co...
