Selenium is a solid nonmetal.
Selenium is a metalliod, you're welcome.
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.

This is a "decomposition" reaction.
calcium hydride
The compound SnH2 would be called either tin(II) hydride or stannous(II) hydride, but I'm not sure such a compound exists. The more common hydride of tin is tin(IV) hydride which is H2Sn, or SnH2.
