| strontium | <chemistry> A metallic element of the calcium group, always naturally occurring combined, as in the minerals strontianite, celestite, etc. It is isolated as a yellowish metal, somewhat malleable but harder than calcium. It is chiefly employed (as in the nitrate) to colour pyrotechnic flames red. Symbol Sr. Atomic weight 87.3. Origin: NL. See Strontia. Source: Websters Dictionary (01 Mar 1998) |
