the atomic no of oxygen is 8 to reach the nearest noble gas electronic configuration it excepts 2 electrons and becomes isoelectronic to Neon.
Only three electrons.
A lone, neutral oxygen atom has 6 electrons in its outer shell, but this is not very stable, so oxygen will tend to gain 2 more electrons in order to get a full, stable shell of 8 electrons.
An oxygen atom is able to attract 2 additional electrons to complete its valence shell and achieve a stable octet configuration. This is because oxygen has 6 valence electrons and needs a total of 8 electrons for stability.
Selinium is a non metal element. There are 34 electrons in a single atom.
Oxygen has six valence electrons and needs two more to fill its outer shell and achieve a stable octet configuration. This is why oxygen typically forms two bonds with other elements, such as in water (H₂O) or carbon dioxide (CO₂). By gaining or sharing two additional electrons, oxygen can attain a stable electronic configuration.
Oxygen wants to gain 2 electrons, so its charge would be 2-, because electrons have a negative charge.
When an oxygen atom gains two electrons to become an oxide ion, it fills its outer energy level and achieves a stable electron configuration known as the octet rule. This results in a complete set of eight electrons, giving it a full valence shell and a charge of -2.
In oxygen, each atom gains two electrons to achieve a stable electron configuration through forming two covalent bonds. This means that each oxygen atom gains two electrons to reach a full valence shell.
The anion of chloride (Cl⁻) has 18 electrons, as it has gained one electron to achieve a stable electron configuration. Chloride has 17 electrons in its neutral state, but when it gains an electron, it becomes Cl⁻ with 18 electrons.
An atom becomes stable by gaining or loosing electrons.
Oxygen can lend two electrons to form a stable compound. Oxygen typically forms bonds by accepting two electrons to complete its outer shell and achieve a stable electron configuration.
Oxygen atoms become more stable when they form compounds because they are able to complete their valence shell by sharing electrons with other atoms. This allows them to achieve a full outer electron shell and become more like the stable noble gases.
The valency of oxygen is two because oxygen typically forms covalent bonds by sharing two electrons with other atoms. This allows oxygen to achieve a stable octet configuration, which is energetically favorable.
When Sulphur becomes Sulphide, it becomes negatively charged with 2 extra negative charges. It is S2-
Only three electrons.
-3 electrons are gained,i.e,3 electrons are lost by Al and 3 electrons are gained by the other atom nearby.
A lone, neutral oxygen atom has 6 electrons in its outer shell, but this is not very stable, so oxygen will tend to gain 2 more electrons in order to get a full, stable shell of 8 electrons.
