My kiddos have chosen to write the report concerning an element and part of it is to draw a picture of a molecule containing the element and the name of the molecule. Can anyone help me out? My ds chose radium and dd chose calcium. I have googled and really am not finding anything but maybe I am not looking for the correct thing. Thanks for any help.

Is it a molecule containing the element or a compound containing the element? A molecule containing the element doesn't make sense to me, but an element containing it does. For example for Calcium they could look up calcium carbonate. Radium will be tough to find something you can draw a picture of because most of it's compounds are colorless. Radium nitrate is a white powder though.

All compounds are molecules. Molecules are groups of songs. So H2 is a molecule as is H2O. Compounds are molecules containing at least two elements. So H2 is not a compound but H2O is.

Did that makes sense?
Calcium is easier than radium for sure. There are a lot of things with calcium in them, like table salt (sodium chloride). Radium is not as common, but you can find things in wikipedia I am fairly certain.

True all compounds are molecules, but when it involves 2 elements bonded together the molecule is usually referred to as a compound so to my brain if they want you to draw a picture of a molecule containing the element I just think it makes more sense to say the compound containing the element. I just thought that might be why she was having trouble finding it. I also thought sodium chloride has sodium and chlorine in it. Calcium chloride is a salt, but it isn't table salt it is the salt they use to de-ice streets. At least that is my understanding.
