Document Summary

First element + second element with ending -ide. Ex: h2o dihydrogen monoxide one two three four five six seven eight nine ten mono di tri tetra penta hexa hepta octa nona deca. Ex: nacl sodium chloride, fecl3 iron (ii) chloride. Prefix hydro + anion + suffix ic + acid. Ex: hcl hydrochloric acid, hf, hbr, hi, and h2s. Ex: hclo hypochlorous acid (clo- is hypochlorite) Change ate to ic ex: hclo3 chloric acid (clo3- is chlorate) Solid has fixed shape, not necessarily rigid and hard. Particles lie next to each other in an array. Liquid has varying shape that conforms to container"s shape, fixed volume. Large distances between particles, moving randomly throughout container. Color, melting point, electrical conductivity, and density. Ice melting, hardness, density, and ability to flow. Ex: passing electric current through water hydrogen and oxygen. An element cannot be broken down into simpler type of matter.
