everything we see in the universe
a group of the same attoms create an element and a group composed of different atoms forms a compound
Yes. Remember that when 2 atoms of the same or different elements combine, it forms a molecule. 2 hydrogen atoms + 1 Oxygen atom = 1 molecule of H20(water). The same holds true for proteins, proteins are composed of amino acids, which are in turn composed of different molecules, which are also composed of different atoms.
A compound is composed of different kinds of atoms that are covalently bonded together. Compounds are made up from atoms of different elements.
Elements and compounds are both composed of atoms. Compounds are composed of two or more atoms of different elements.
A cell is larger, as it is composed of many atoms of different elements.
Compounds are composed of two or more atoms of different elements.
That varies with the substance. H2O is composed of 3 atoms. C6H12O6 is composed of 24 atoms.
No.Sound is not composed of atoms.
EVERYTHING is composed of atoms.
A substance composed of two or more atoms of the same element is just a pure substance/element, a substance composed of different atoms is called a compound
Atoms are elements, not compounds. Compounds are composed of two or more different atoms. For example, the element carbon, with the symbol C, is composed of atoms. If you combine carbon and oxygen to make carbon dioxide (CO2) then you have a compound, composed of molecules, each of which have 3 atoms, one carbon and two oxygen.
a mixture means there are no true bonds between the atoms. Molecules have either ionic or covalent bonds between the atoms.
