Atoms consist of electrons (negative charge), protons (positive charge), and neutrons (neutral charge), while molecules consist of atoms.
Atoms. Molecules are two or more atoms together.
Hydrogen is a non metal element. Atomic Mass of it is 1.
yes
Sodium does not consist of molecules but of individual sodium atoms.
Nitrogen gas consists of N2 molecules.
Yes, hydrogen gas is a compound. It is made up of molecules which consist of two atoms of hydrogen, an element. It just happens that the same name is used for the gas as for the element.
Either one. This is incorrect. The correct answer would be that it is made of separate atoms because iron is an element or a pure substance. So, therefore it didn't combine with anyother atoms to form a molecule and that being said it is strictly made up of separate atoms and not molecules. Definitely not either one.
No. Helium consists of individual atoms and does not form molecules or compounds.
Molecules consist of two or more atoms which are joined together.
All states of matter do not necessarily have molecules. The noble gases consist of individual atoms, and ionic compounds consist of ions, or formula units. All states of matter must contain atoms, molecules, or ions, because matter is made of atoms, molecules, and ions.
A compound is a substance in which two or more elements are bonded together chemically. There are some molecules, such as oxygen, O2, that consist of two or more atoms of the same element. Apart from these, all molecules are compounds. Please see the link.
