), a negatively charged ion with two electrons. This unique state makes hydrides essential for everything from cleaning lab equipment to powering future spacecraft. 1. The Three Faces of Hydrides
: Formed with transition metals like palladium or titanium. In these, hydrogen atoms actually "squeeze" into the gaps (interstices) of the metal's crystal lattice. This creates a material that can act like an alloy and conduct electricity. hydride
Hydrides are generally categorized by the type of chemical bond they form with other elements: ), a negatively charged ion with two electrons
: Formed when hydrogen bonds with non-metals or less electropositive elements. Common examples include familiar substances like water ( H2Ocap H sub 2 cap O ), ammonia ( NH3cap N cap H sub 3 ), and methane ( CH4cap C cap H sub 4 2. High-Tech Applications The Three Faces of Hydrides : Formed with
