Question
The Oxygen Family element, Selenium (Se) has a valence number of , and an oxidation number of .
Solution
It seems like you forgot to provide the valence number and oxidation number for Selenium (Se). However, I can tell you that Selenium is in the Oxygen family (Group 16) on the periodic table, which means it typically has a valence number of 6 because it has six electrons in its outer shell. The oxidation number of Selenium can vary depending on the compound it is in, but its common oxidation states are -2, +4, and +6.
Similar Questions
The oxidation number for an element can be based on the number of electrons it needs to to have a full valence shell. For example, the oxidation number 3- means that the element has valence electrons and that it will gain electrons to have a full valence shell. This will cause this element to become a charged (-3) ion.
Which element has the same number of valence electrons as As (arsenic)?A.Sb (antimony)B.Ge (germanium)C.Al (aluminum)D.Se (selenium)
