Over 55 lakh students rely on UrbanPro.com, to fulfill their learning requirements across 1,000+ categories. Thanks Wonderopolis! Explain. Since these atoms are much larger than a hydrogen atom, the electrons will tend to stay closer to the larger atom, giving it a slightly negative charge and the hydrogen atom a slightly positive charge. When two or more atoms chemically bond together, they form a molecule. A chemical bond is a force of attraction between atoms or ions. i Such links are known to arise from the deployment of the electrons of the outer shells of atoms, the so-called valence shells.
