Best Answer

Oxygen has 6 valence electrons in its outer shell, which allows it to form two bonds with other atoms to achieve a stable octet configuration. This results in an oxidation state of -2 for oxygen in most compounds, making its valency 2.

What is the valency of oxygen?

Oxygen has a valency of 2. This means that it can form up to two bonds with other elements in chemical compounds.


If one atom of oxygen combines with two atoms of hydrogen the valency of oxygen will be?

The valency of oxygen in this scenario would be 2. Oxygen typically has a valency of 2 when it forms compounds.


Does oxygen exihibit variable valency?

No, oxygen typically exhibits a fixed valency of -2 in most compounds.


What is the valency of oxygen in suboxides?

The valency of oxygen in suboxides can vary, but it is typically less than its usual valency of 2 in oxides. Suboxides contain oxygen atoms with a valency of 1 or less, resulting in a lower overall valency for oxygen in these compounds.


What is the valency of trioxide?

S = +6 valency O = -2 valency


What is the valency and electronic configuration of oxygen?

Electron configuration for oxygen (O) is 1s2 2s2 2p4. The valency is 2-.


How is the valency of oxygen two?

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.


What is the valence atoms of oxygen?

Oxygen has the valency of 2 in most of the compounds.


What is the valency of phosphorus in P2O5?

The valency of phosphorus in P2O5 is +5 because each oxygen atom has a valency of -2, giving a total of -10 for the oxygen atoms. To balance the charge in the compound, the phosphorus atom must have a valency of +5.


What is the valency of Dioxonitrate?

The valency of dioxonitrate (NO2-) is -1. Each oxygen atom in the dioxonitrate ion has a valency of -2, while the nitrogen atom has a valency of +3, resulting in an overall charge of -1 for the ion.


What is the valency of phosporous in P2O5?

The valency of phosphorus in P2O5 is +5. This is because each oxygen atom has a valency of -2, and since there are 5 oxygen atoms in P2O5, the total negative charge is -10. To balance this, the phosphorus atom must have a valency of +5.
