Molecule
A molecule is a group of atoms joined by chemical bonds. These atoms can be of the same element or different elements, forming compounds. The bonds can be covalent, ionic, or metallic, depending on how the atoms interact with each other. Molecules are the fundamental building blocks of chemical substances.
a group of atoms bonded together, representing the smallest fundamental unit of a chemical compound that can take part in a chemical reaction.
a molecule
A molecule is a group of more than one atom joined together that acts like a single particle. The atoms in a molecule are held together by chemical bonds. Molecules can be composed of different types of atoms and can range in size and complexity.
Yes
Such a group is often called a "radical".
A compound is 2 or more elements joined by chemical bonds
Molecule
They are joined together by molecular bonds. These bonds can only be separated/broken by chemical reactions. Other separation methods like filtering or distilling will not break these bonds. Hope this helps
Noble gases do not usually form chemical bonds.
