Phosphorus has to gain a total of 3 electrons to achieve a noble gas configuration.
You can find this for any non-metal because the last digit of its group number is the number of valence electrons it has. For example Phosphorus has 5 and Sulfur has 6. In order to achieve a noble gas electron configuration, you must have 8 valence electrons, so phosphorus must gain 3.
Selenium should gain two electrons and lose six electrons to achieve a noble gas electron configuration.
Chemical properties depend on electron configuration. By either gaining or losing electrons, an atom changes its electron configuration and therefore its chemical properties also change.The atoms of an element will react to achieve a noble-gas configuration. The atoms will either gain or lose electrons to achieve such a configuration.
Only three electrons.
This atom must gain 3 electrons to achieve an octet.
Iodine accepts one electron to achieve noble gas configuration. Strontium loses two electrons to achieve noble gas configuration. Nitrogen accepts three electrons to achieve noble gas configuration. Krypton already has a noble gas configuration.
Phosphorus, like all atoms, tries to achieve a full electron shell. For Phosphorus to achieve its full shell and obtain an electron configuration that is isoelectronic with Argon, it must gain 3 electrons. Therefore, Phosphorus forms a -3 anion.
Phosphorus ion (PĀ³ā») typically gains three electrons to achieve a stable electron configuration. As a result, it carries a charge of -3 and has a full outer electron shell.
Selenium should gain two electrons and lose six electrons to achieve a noble gas electron configuration.
They achieve the electron configuration of a noble gas.
A stable electron configuration.
Oxygen atoms need to share or gain two electrons in order to achieve a stable electron configuration.
nitrogen has 5 valence electrons. It should gain 3 electrons to achieve a noble gas configuration.
Losing an electron cesium has a noble gas configuration.
Two electrons
Two electrons.
They achieve stable configuration by sharing their electrons in their outermost shell.
