Asked by Freddo
Hi
Can anyone help me determine the valency of selenium in hydrogen selenide... how do you work this out ???
Thank you ..
Freddo ..
H2Se is the formula for hydrogen selenide. The valence of H is +1, there are two of them for a total charge of +2. For the compound to be zero, and it must be zero, the Se must have a valence of -2.
Thank you Dr Bob
