Electron Configuration Of Sodium And Chlorine

Chlorine, with seven valence electrons, can gain one electron to attain the configuration of argon.

Electron configuration of sodium and chlorine. To save room, the configurations are in noble gas shorthand. Full ground state electron configuration: How does the atomic radius change across a period of the periodic table?.

Atomic number of chlorine(cl) atom is 17. As demonstrated here, a sodium atom (na) has one valence electron in the third principal energy level. The chlorine gains an electron, so it has the same electron configuration as the next element in the periodic table, argon.

(b) how many electrons are there in the outermost shell of (i) a sodium atom, and (ii) a chlorine atom? There are 118 elements in the periodic table. Its electron configuration is \(1s^2 2s^2 2p^6 3s^1\).

(a) write down the electronic configuration of (i) sodium atom, and (ii) chlorine atom. The energy required to transfer an electron from a sodium atom to a chlorine atom (the difference of the 1st ionization energy of sodium and the electron affinity of chlorine) is small: Either convention can be used.

Chlorine has an atomic number of 17. This list of electron configurations of elements contains all the elements in increasing order of atomic number. Each element has a unique atomic structure that is influenced by its electronic configuration, which is the distribution of electrons across different orbitals of an atom.

The electron configuration of chlorine is illustrated below. When sodium (na) and chlorine (cl) are combined, the sodium atoms each lose an electron, forming cations (na+), and the chlorine atoms each gain an electron to form anions (cl−). Sodium chloride is the most common compound of chlorine whereas the simplest is hydrogen chloride.
