The elements have the same number of electrons in the outer ring so they react with the same substances
In an atom, the nucleus is composed of positive charged particles called protons and neutrons that have zero charge. Most of the mass of the atom is in the nucleus. The atom is surrounded by orbits of electrons that are mobile and are negatively charged.
Answer:
b Van der Waals - Hydrogen Bond - Covalent Bond - Ionic Bond
Explanation:
Generally interatomic bonds are stronger compared to intermolecular forces.
Van der waals and hydrogen bonds are intermolecular bonds that forms between molecules or even compound.
Covalent and Ionic bonds are interatomic forces.
Van der waals forces are the weakest forces of attraction and hydrogen bonds are very strong forces.
Ionic forces are the strongest interatomic forces.
