Why the valency of oxygen is 2?

Anonymous

∙ 11y ago

Updated: 6/2/2024

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.

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.

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 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 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.

What is the valancy for Cr2O7?

The valency of Cr2O7 is -6. This is because each oxygen atom has a valency of -2, giving a total valency of -14 for the seven oxygen atoms. Since the overall charge of the Cr2O7 ion is -2, the valency of the two chromium atoms must be +12 to balance out the negative charge.
