In compounds such as H2Se yes it is, and the oxidation number ofd -2 is well known. However there are many compounds where Se has other oxidation numbers (Se is very similar to Sulfur another group 16 elemnt) for example compounds where Se has an ox number of +4, SeF4, +6, SeF6, -1 in the polyselenide compound Na2Se2

Determine the oxidation number os Se in K2SeO4?
The oxidation number of Se in K2SeO4 is +6. This is determined by considering the oxidation numbers of K(+1) and O(-2) in the compound and using the overall charge of the compound (zero) to calculate the oxidation number of Se.
What is the Oxidation number of Se8?
Zero. Se8 is th elemental form of selenium and oxidation numbers are not applied to elemental forms. Se8 is a ring and each selenium is bound to two others.
What is the oxidation number of Cr in CrSe?
The known oxidation numbers of chromium are +2, +3, and +6, while the known oxidation numbers of selenium are -2, +4, and +6. Within this constraint, the only oxidation numbers that can match the formula given are -2 for selenium and +2 for chromium.
What elements have an oxidation number of -2?
Predominantly those in wide form periodic table column 16, especially oxygen and sulfur.
What is the oxidation number of N?
The oxidation number of N, or Nitrogen, is N-3. Nitrogen is in group five, meaning it has five valence electrons. It needs to get eight to be stable. So it will gain 3 electrons to be stable. If you gain electrons, that makes it a negative number since electrons are negative in charge.
Determine the oxidation number os Se in K2SeO4?
The oxidation number of Se in K2SeO4 is +6. This is determined by considering the oxidation numbers of K(+1) and O(-2) in the compound and using the overall charge of the compound (zero) to calculate the oxidation number of Se.
What is the predicted oxidation number for Al and Se?
0 in their compounds, +3 for Al and -2 for Se in their compounds.
What is the oxidation state for selenium?
Oxidation number of Se is +6. Oxidation number of O is -2.
What is the Oxidation number of Se8?
Zero. Se8 is th elemental form of selenium and oxidation numbers are not applied to elemental forms. Se8 is a ring and each selenium is bound to two others.
What is the oxidation number of Cr in CrSe?
The known oxidation numbers of chromium are +2, +3, and +6, while the known oxidation numbers of selenium are -2, +4, and +6. Within this constraint, the only oxidation numbers that can match the formula given are -2 for selenium and +2 for chromium.
What elements have an oxidation number of -2?
Predominantly those in wide form periodic table column 16, especially oxygen and sulfur.

What is the oxidation state for Se?
Selenium's most common oxidation state is -2, as it is both a non metal, and is located in the periodic table in the same group as O and S.
What is the atomic number of se?
The atomic number of Selenium is 34.
Is selenium cation or anion?
Selenium is an non-metal element that can exist in various oxidation states, including as a cation (Se^2+) or an anion (Se^2-, Se^4-, etc.). The oxidation state of selenium determines whether it acts as a cation or anion in a given compound.
