the atomic no of oxygen is 8 to reach the nearest noble gas electronic configuration it excepts 2 electrons and becomes isoelectronic to Neon.
An oxygen atom (O) becomes an oxide ion (O²⁻) by gaining two electrons. This process occurs because oxygen has six valence electrons and needs two more to achieve a stable octet configuration. When it gains these electrons, the oxygen atom becomes negatively charged, resulting in the oxide ion symbol O²⁻.
When the element oxygen gains two electrons, it becomes stable and achieves a full outer electron shell, resembling the noble gas argon. This process results in the formation of an oxide ion (O²⁻), which has a complete octet, similar to argon's electron configuration. Thus, oxygen's stability is enhanced through the acquisition of these additional 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.
Only three 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.
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.
An oxygen atom (O) becomes an oxide ion (O²⁻) by gaining two electrons. This process occurs because oxygen has six valence electrons and needs two more to achieve a stable octet configuration. When it gains these electrons, the oxygen atom becomes negatively charged, resulting in the oxide ion symbol O²⁻.
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.
When the element oxygen gains two electrons, it becomes stable and achieves a full outer electron shell, resembling the noble gas argon. This process results in the formation of an oxide ion (O²⁻), which has a complete octet, similar to argon's electron configuration. Thus, oxygen's stability is enhanced through the acquisition of these additional electrons.
An atom becomes stable by gaining or loosing electrons.
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.
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.
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-
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.
