Chlorine need one extra negatively charged electron to be a noble gas.
Chlorine has only one half-filled orbital. This means that it can only bond with one other atom.
Krypton is a noble gas and need not lose electrons. It is already stable.
Oxygen should gain 2 electrons to achieve noble gas configuration
An atom of nitrogen needs 3 more electrons to achieve a stable, noble gas electron configuration. This would give nitrogen a total of 8 valence electrons, making it isoelectronic with a noble gas (in this case, neon).
Magnesium has an atomic number of 12, which means it has 12 electrons. To achieve a noble gas configuration, magnesium would need to lose both of its valence electrons. This can be achieved through chemical reactions, where magnesium can form ionic compounds by transferring its electrons to other elements, such as oxygen or chlorine.
Chlorine has only one half-filled orbital. This means that it can only bond with one other atom.
chlorine would need only one electron to attain an octet structure.
Krypton is a noble gas and need not lose electrons. It is already stable.
Oxygen should gain 2 electrons to achieve noble gas configuration
One more electron.
You would need 1 more electron to make a Chlorine atom stable with 7 valence electrons. This additional electron would allow Chlorine to achieve a full valence shell of 8 electrons, following the octet rule.
They should gain 2 electrons to attain noble gas electronic configuration. (it doesn't become a noble gas as the number of protons are not same)
4 but it will need energy, so carbon gain 4 electrons to achieve a noble gas configuration.
An atom of nitrogen needs 3 more electrons to achieve a stable, noble gas electron configuration. This would give nitrogen a total of 8 valence electrons, making it isoelectronic with a noble gas (in this case, neon).
A chlorine atom would need to lose one electron to have a stable electron arrangement like neon, which has a full valence shell of electrons. Chlorine normally has 7 electrons, but by losing one electron, it will have 8 electrons in its outer shell, achieving stability.
Magnesium has an atomic number of 12, which means it has 12 electrons. To achieve a noble gas configuration, magnesium would need to lose both of its valence electrons. This can be achieved through chemical reactions, where magnesium can form ionic compounds by transferring its electrons to other elements, such as oxygen or chlorine.
11 electrons makes the third energy level complete. One
