Valence of Elements in Compounds with Oxygen:

To calculate the valence of elements in compounds with oxygen, we need to consider the oxidation states of the elements in the compounds. Here are the valence calculations for the given compounds:

1. Carbon Monoxide (CO): - Carbon (C) has a valence of +2 in carbon monoxide (CO) [[1]]. - Oxygen (O) has a valence of -2 in carbon monoxide (CO) [[1]].

2. Nitrous Oxide (N2O): - Nitrogen (N) has a valence of +1 in nitrous oxide (N2O) [[2]]. - Oxygen (O) has a valence of -2 in nitrous oxide (N2O) [[2]].

3. Tungsten Trioxide (WO3): - Tungsten (W) has a valence of +6 in tungsten trioxide (WO3) [[3]]. - Oxygen (O) has a valence of -2 in tungsten trioxide (WO3) [[3]].

4. Nitrogen Dioxide (NO2): - Nitrogen (N) has a valence of +4 in nitrogen dioxide (NO2) [[4]]. - Oxygen (O) has a valence of -2 in nitrogen dioxide (NO2) [[4]].

5. Sulfur Dioxide (SO2): - Sulfur (S) has a valence of +4 in sulfur dioxide (SO2) [[5]]. - Oxygen (O) has a valence of -2 in sulfur dioxide (SO2) [[5]].

6. Boron Trioxide (B2O3): - Boron (B) has a valence of +3 in boron trioxide (B2O3) [[6]]. - Oxygen (O) has a valence of -2 in boron trioxide (B2O3) [[6]].

Please note that these valence calculations are based on the oxidation states commonly observed in these compounds. However, it's important to remember that oxidation states can vary depending on the specific chemical environment and bonding interactions.
