If the question is "What is the likely bond angle for selenium hydride," then the answer is 105 degrees, just like a water molecule.
it can bond with mercury and zinc!
Selenium dioxide has a covalent or molecular bond.
NaH (sodium hydride) is an ionic compound and forms an ionic bond.
Lithium hydride is an ionic compound.
Since Selenium is in the same column as Oxygen and Sulfur, you would expect it to bond just like them. As a halogen, chlorine wants to make one bond so your final answer would be. Cl-Se-Cl with two lone pairs (that's 4 electrons) on selenium and 3 lone pairs (that's six electrons) on EACH chlorine.
Hydrogen selenide has two hydrogen atoms attached to a selenium atom in a bent configuration. This forms an H-Se-H with a bond angle of 91 degrees.
slightly less than 109.5 deg.
covalent bond in NH3
CaH2, calcium hydride, is ionic., Ca2+ 2H-
it can bond with mercury and zinc!
This bond is ionic.
Selenium dioxide has a covalent or molecular bond.
CuH, copper hydride is possible, but the bond is weak and unstable.
NaH (sodium hydride) is an ionic compound and forms an ionic bond.
It is a covalent bond.
Lithium hydride is an ionic compound.
Ionic. But it does have covalent bonding characteristics aswell
