The number of protons and neutrons controls the weight of an atom.
The total weight of the protons and the neutrons.
It's much simpler than you're probably thinking. You use the term gram atomic weight for atoms, and the term gram molecular weight for molecules. That's all. The gram molecular weight of a molecule is the sum of the gram atomic weights of the atoms making up that molecule.
Carbon, oxygen, and another oxygen atom make up carbon dioxide.
A moleule has more particles than an atom, since a molecule is made up of two or more atoms chemically bonded together. An atom is the basic unit of an element, consisting of protons, neutrons, and electrons.
A molecule of an element is a molecule made up of the same substance that can exist as an atom; for example, oxygen as O2.
The total weight of the protons and the neutrons.
Is not a molecule or a atom it is a compound
a molecule is made up of more then 1 type of atom. also there are 1 or 2 elements that have molecules with only 1 atom. The atom is the basic unit of matter and the molecule is the smallest unit of compounds.
Its a Molecule Its a Molecule
No, a single atom is not considered a molecule. A molecule is made up of two or more atoms bonded together.
It's much simpler than you're probably thinking. You use the term gram atomic weight for atoms, and the term gram molecular weight for molecules. That's all. The gram molecular weight of a molecule is the sum of the gram atomic weights of the atoms making up that molecule.
No...but many atoms do.
Though some molecules are made up from a single element, many of the molecules exist aren't from a single element.
nucleus
Ferric oxide is a compound made up of iron and oxygen atoms. It is not an atom or a molecule on its own, but rather a combination of atoms.
"element" (2 make up a molecule)
an element is an atom or molecule made up of a single type of atom a compound is a molecule made up of two or more different elements
