The electron structure of a chemical element Indicate the location of electrons on shells.
Carbon owns 6e- and 6p+ so the electronic structure is K2 L4 .
Group 1 elements have one electron in their outermost energy level, giving them an electronic configuration of ns1, where n represents the energy level. For example, lithium has an electronic structure of 1s2 2s1, sodium has an electronic structure of 1s2 2s2 2p6 3s1, and potassium has an electronic structure of 1s2 2s2 2p6 3s2 3p6 4s1.

Sodium has an electronic structure of 2, 8, 1 with one electron in its outermost shell, while chlorine has an electronic structure of 2, 8, 7 with seven electrons in its outermost shell. This difference in electron configuration determines their chemical properties, with sodium being a reactive metal and chlorine being a reactive nonmetal.
Both lithium and sodium belong to group 1 of the periodic table, so they both have one valence electron. This electron configuration makes them highly reactive, as they tend to lose this electron to achieve a stable electronic configuration.
The electron-pair geometry of CS2 is linear because the Lewis structure is S=C=S. Double bonds act as one electron pair to help determine electron-pair geometries of molecules according to VESPR theory
The element with electronic structure 2.7 is lithium (Li) with an atomic number of 3. It has 2 electrons in the first energy level and 1 electron in the second energy level.
The electron cloud refers to the region around a nucleus where an electron is most likely to be found. It represents the probability of finding an electron at a particular location in an atom. The cloud is not a physical structure but rather a mathematical representation of the electron's behavior within an atom.
The number of electrons needed to be lost/gained to gain a stable electronic structure. For example, Sodium needs to lose just 1 electron to make its electronic structure stable, so the ion it forms is Na+ .
Beryllium has an atomic number of 4, so its electronic structure is 2-2, meaning it has 2 electrons in its inner shell and 2 electrons in its outer shell. Its electron configuration is 1s^2 2s^2.
