How many atoms are there in 30.4 g of selenium?
To determine the number of atoms in 30.4 g of selenium, you first need to calculate the number of moles using the molar mass of selenium (78.97 g/mol). Then, use Avogadro's number (6.022 x 10^23 atoms/mol) to find the number of atoms in that amount of selenium. In this case, there are approximately 3.86 x 10^22 atoms in 30.4 g of selenium.
How many electrons will selenium lose or gain in forming an ion?
Selenium may lose 2, 4 or 6 electrons and may gain 2 electrons.
What is the elemental selenium in selenium dioxide monohydrate?
The elemental selenium in selenium dioxide monohydrate exists as Se(IV) in the +4 oxidation state. It is bonded to two oxygen atoms in a linear configuration. The oxygen atoms are bound to the selenium atom in a double bond.
How many bonds can selenium form with hydrogen?
Each hydrogen can form one bond with selenium. Each selenium atom can form two bonds, one with each hydrogen (2 hydrogen atoms total).
How many atoms does it to take to have a selenium and oxygen bond?
One atom of Se and one atom of O.

How many atoms does it to take to have a selenium and oxygen bond?
One atom of Se and one atom of O.
What atoms is unlikely to form a positively charged ion potassium selenium barium silver?
Barium is unlikely to form a positively charged ion because it is an alkaline earth metal with a strong tendency to lose electrons and form a 2+ ion.
What is the binary compound SeO?
The binary compound SeO is selenium dioxide. It is composed of one selenium atom and two oxygen atoms. Its chemical formula is SeO2.
