I'm not an expert (I'm 11 years old) but I'm very sure Carbon (C), Radium (Ra), Oxygen (O) and Yttrium (Y). Carbon can be found in column 4a, Radium in column 2a, Oxygen in column 6a and Yttrium in column 1b which if you didn't know, comes after the row 2a (have a labeled column Periodic Table to understand this)
I hope you find this of help =)
Hydrogen, oxygen, nitrogen, carbon, sulphur
carbon, hydrogen, oxygen....
in science BCNO is the family on the periodic table that consists of boron,carbon nitrogen,and oxygen.BCNO!!!!!!! :)
Mainly carbon, nitrogen, hydrogen and oxygen.
No, it is not. It is a compound, not an element. RNA contains carbon, nitrogen, hydrogen, oxygen, and phosphorus.
Hydrogen, Helium, Oxygen, Nitrogen, Xenon, There are plenty to choose from, just look along the right-hand side of the periodic table
No. Carbon, nitrogen, and oxygen are separate elements.
Hydrogen and Nitrogen. Or oxygen and carbon dioxide, or carbon monoxide.
Carbon, Hydrogen, Nitrogen, Oxygen
Non-metals are on the right side of the periodic table. Carbon, nitrogen, oxygen, fluorine, sulfur, etc are nonmetals.
Cereals contain organic compounds with carbon, oxygen, hydrogen, nitrogen.
The following four elements make up 90 percent of the mass of living things: Oxygen - 65% Carbon - 18.5% Hydrogen - 9.5% Nitrogen - 3.2%
