When a calcium atom loses its valence electrons the ion formed has an electron configuration that is the same as an atom of?

Argon. Calcium has the electron configuration 1s2 2s2 2p6 3s2 3p6 4s2, and when it loses its valence electrons (the outermost 4s2 electrons) it has a configuration identical to argon. If you don't know about sublevels, then disregard that. Calcium has a configuration of 2-8-8-2, and when it loses its 2 valence electrons, it has a configuration identical to argon in the ground state. Hope that cleared it up


What is the valence configuration of argon?

What is the abbreviated electron configuration for argon?

The abbreviated electron configuration for argon is [Ne] 3s^2 3p^6. The [Ne] represents the electron configuration of the noble gas neon, which has the same electron configuration as the inner electrons of argon.


What is the electric configuration of argon?

Argon does not have an electric configuration.


Is sodium or argon more reactive and why?

Argon has completely filled valence orbitals and hence is unreactive. Sodium has one valence electron. If sodium loses this electron it will attain the stable electron configuration of the nearest noble gas (argon) and hence is reactive.


Does KR and AR have the same valence electron configuration?

Krypton and argon both have 8 valence electrons. This is true of all noble gases except helium, which has only 2 valence electrons.


What is the element with a valence electron configuration of 2s2?

The element with a valence electron configuration of 2s2 is beryllium. Beryllium has 4 electrons, with 2 in the 2s subshell, which makes it have a valence electron configuration of 2s2.


Electron configuration for argon?

The electron configuration for argon is 1s2 2s2 2p6 3s2 3p6. Argon has 18 electrons and is found in the noble gas group, which means it has a stable configuration.


What is the valence electron configuration of selenium?

The valence electron configuration of selenium is 4s2 4p4, meaning it has 6 valence electrons.


What is the name of the element with a valence electron configuration of 3s23p3?

The electron configuration of phosphorus is [Ne]3s2.3p3.


What are the noble gases that Na 1 and Cl-1 resemble in there electron configuration?

Sodium (Na) is in Group 1 of the periodic table and has one valence electron, similar to the noble gas configuration of helium (He). Chlorine (Cl) gains one electron to achieve a stable electron configuration, resembling the noble gas configuration of argon (Ar).


What is the valence electron of argon?

Valence electrons are the outer layer of electrons, the part that reacts. Argon is a noble gas, so it has a full valence electron level. It has eight valence electrons.
