	RIA - Hydrogen selenide
		Hydrogen selenide may be produced as a by-product and liberated during processes where selenium compounds may be present for example, during the smelting of alloys, during lead battery manufacture and during the production of studio glass.
		The OES for hydrogen selenide i.e 0.05 ppm 8-hour TWA has been withdrawn and in the meantime until a MEL is assigned to the gas, ACTS considers that the general requirement on employers under the Control of Substances Hazardous to Health (COSHH) Regulations 1999 will ensure adequate control of exposure to this substance.
		Hydrogen selenide may also be produced as a by-product where selenium compounds are present such as during alloy smelting but it is expected to be negligible because of the relatively trace amounts of selenium likely to be present in the parent selenium.

		In main group element hydrides electronegativity of an element respective to hydrogen determines the compound to be either of the first two types.
		Hydrogen gas is liberated proportional to the applied temperature and pressure but not to the chemical composition.
		Various metal hydrides are currently being studied for use as a means of hydrogen storage in fuel cell-powered electric cars and batteries.

	Selenium Compounds \| Technology Transfer Network Air Toxics Web site \| US EPA
		Acute (short-term) exposure to elemental selenium, hydrogen selenide, and selenium dioxide by inhalation results primarily in respiratory effects, such as irritation of the mucous membranes, pulmonary edema, severe bronchitis, and bronchial pneumonia.
		Acute animal tests in rats, mice, and guinea pigs, have shown hydrogen selenide to have extreme toxicity from inhalation exposure, sodium selenite to have extreme toxicity from oral exposure, and elemental selenium to have low toxicity from oral exposure.
		This LOAEL is from the critical study used as the basis for the CalEPA chronic reference exposure level for hydrogen selenide.

	Unique Properties of Water
		The reason for the high melting and boiling temperatures is the hydrogen bonding between water molecules that causes them to stick together and to resist being pulled apart which is what happens when ice melts and water boils to become a gas.
		In the case of liquid water, because the hydrogen bonds suppress vibration, the temperature does not increase as much as it would without the presence of strong hydrogen bonds.
		Because of the hydrogen bonding it is very difficult to separate the water molecules from the surface of a liquid to form a vapor.

	Hydride - Wikipedia, the free encyclopedia
		According to IUPAC convention, by precedence (stylized electronegativity), hydrogen falls between group 15 and group 16 elements.
		As the name suggests, the hydrogen is covalently bonded to more electropositive p-block (boron, aluminium and Group 4-7) elements and beryllium.
		In these, molecules of hydrogen dissociate and hydrogen atoms settle in the octahedral or tetrahedral holes in the metal crystal lattice called the interstitial sites.
