Chemist's Vows

Chemist Clara swore a solemn vow—from now on, she can only speak atomic element symbols. Of course, this limits her ability to talk. She can say, for example, “I Am CLaRa” (as I is the symbol of iodine, Am is americium, C is carbon, and so on). She can also say “InTeRnAtIONAl”, but she has a lot of trouble with “collegiate”, “programming”, and “contest”.

Given a word, determine whether Clara can speak it (i.e., if it is a concatenation of atomic symbols). Without your help, she might as well have taken silence vows!

You may identify upper- and lowercase letters, as Clara cannot speak uppercase anyway. In case you forgot the elements' symbols, here is the complete periodic table:
