WebbThe new grouping is typically more stable—less likely to react again—than its component atoms were when they were separate. A more or less stable grouping of two or more atoms held together by chemical bonds is called a molecule. The bonded atoms may be of the same element, as in the case of H 2, which is called molecular hydrogen or ... WebbIndividual atoms are extremely small; even the largest atom has an approximate diameter of only 5.4 × 10 −10 m. With that size, it takes over 18 million of these atoms, lined up side by side, to equal the width of your little finger (about 1 cm). Most elements in their pure form exist as individual atoms.
