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 atoms selenium lose?
Selenium typically loses 2 electrons to achieve a stable electron configuration. This results in the formation of a 2+ ion for selenium.
What is Se4Br7?
Se4Br7 is the chemical formula for selenium tetrabromide. It is a compound composed of selenium and bromine atoms, with four selenium atoms and seven bromine atoms in each molecule. Selenium tetrabromide is a red-brown solid that is primarily used in chemical synthesis.
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.
What is the binary compound SeO?

Is selenium monoxide ionic or covalent?
Selenium monoxide is a covalent compound. It is composed of selenium and oxygen atoms bonded together by sharing electrons, forming covalent bonds.
What are selenium ions?
Selenium ions refer to selenium atoms that have gained or lost electrons to become positively or negatively charged. They can exhibit different chemical properties compared to neutral selenium atoms, depending on the number of electrons gained or lost.
How do selenium and calcium bond?
Selenium and calcium do not typically bond together. Selenium tends to form bonds with oxygen or sulfur atoms, while calcium commonly forms bonds with oxygen atoms. Each element tends to form stable compounds with specific types of atoms rather than with each other.
What is the compound bonding of Se2S6?
The compound Se2S6 is a covalent compound made up of selenium (Se) and sulfur (S) atoms. In this compound, selenium forms a diatomic molecule (Se2) and reacts with six sulfur atoms. The bonding is mainly covalent, as both selenium and sulfur atoms share electrons to achieve a stable electron configuration.
What is formula for Selenium Hexafluoride?
Sulfur hexachloride is an inorganic compound consisting of two different elements. The prefix hexa indicates that there are six chloride atoms. Thus, the formula is SCl6. Note that this compound does not obey the octet rule.
