1s2,2s2,2p6,3s2,3p3
The electron configuration for a neutral atom of chlorine is 1s2 2s2 2p6 3s2 3p5. Chlorine has 17 electrons, and this configuration indicates the distribution of those electrons in its various energy levels.
Neutral calcium's electron configuration is 1s2 2s2 2p6 3s2 3p6 4s2. Ca2+ is the ion of calcium, which means that it has 2 less electrons than neutral calcium. Therefore, its electron configuration is 1s2 2s2 2p6 3s2 3p6.
An atom of sodium has one valence electron. When a sodium atom loses this electron to another atom, it becomes a sodium ion.
Cations are formed by atoms losing electrons, resulting in a positively charged ion. This occurs when atoms from metals and certain nonmetals give up electrons to achieve a stable electron configuration. The loss of electrons creates a deficiency of negative charge, leading to a positive charge on the cation.
This is due to the difference between the two elements regarding their valence electrons as neutral elements. Sodium has a single electron in its valence shell, which it gives up to have a stable octet; by giving up one electron, sodium acquires a 1+ charge. Magnesium has two electrons in its valence shell that it will give up to have a stable octet; by giving up two electrons, magnesium acquires a 2+ charge.
The electron configuration for a neutral atom of chlorine is 1s2 2s2 2p6 3s2 3p5. Chlorine has 17 electrons, and this configuration indicates the distribution of those electrons in its various energy levels.
The electron configuration for a neutral arsenic atom is 1s^2 2s^2 2p^6 3s^2 3p^6 3d^10 4s^2 4p^3.
Neutral calcium's electron configuration is 1s2 2s2 2p6 3s2 3p6 4s2. Ca2+ is the ion of calcium, which means that it has 2 less electrons than neutral calcium. Therefore, its electron configuration is 1s2 2s2 2p6 3s2 3p6.
Losing an electron cesium has a noble gas configuration.
Electron configuration is a term applied to chemical elements not to compounds.
Two electrons
Silver has to give up 1 electron to achieve a pseudo noble gas electron configuration. With its atomic number being 47, silver has an electron configuration of [Kr] 4d^10 5s^1. Giving up its one valence electron from the 5s orbital will result in a stable pseudo noble gas electron configuration similar to argon.
Boron must give up 3 electrons in order to achieve a noble-gas electron configuration.
Silver (Ag) has 47 electrons. To achieve a pseudo-noble gas electron configuration, silver would need to give up one electron to match the electron configuration of the noble gas, krypton (Kr), in which the outermost energy level is full. This would leave silver with 46 electrons.
A stable electron configuration for a chlorine ion can be achieved by gaining one electron. This would give the chlorine ion a full outer shell of electrons. The symbol for a stable chlorine ion with an extra electron would be Cl-.
nitrogen should give 5 electrons (or better gain 3 electrons) to attain noble gas configuration.
Sodium gives away one electron to achieve a stable electron configuration, forming a cation with a +1 charge.
