Is iron a hydroxide?

If you want to do science you need to learn the words. You have to take chemistry classes for a year and a half just to learn the words before they try to teach you any actual chemistry.

You do have a printed periodic table, right? You can get the information at www.chemicalelements.com/index.html but you really need your own printed copy to carry with you. It will be a primary reference for everything you do.

There is a diagonal line, B-C, Si-P, Ge-As, Sb-Te, and Po-At. Elements to the left of the line are metals, meaning they lose an electron easily, elements to the right of the line are non-metals, and elements on the line are semiconductors. Iron is one of the elements, a metal.

Hydroxide means an OH group in the compound. There are dozens of compounds with iron, hydrogen, and oxygen. en.wikipedia.org/wiki/Iron_oxide#Hydroxides
