Describing the structure of an atom
WebApr 5, 2024 · Elements are characterized by the mass of their atoms. Dalton stated that all atoms of an element are identical in shape, size, and mass. When atoms are involved in chemical reactions, they combine in small whole-number ratios to … WebIn the same way, if energy is added to an atom, an electron can use that energy to make a quantum leap from a lower to a higher orbit. This energy can be supplied in many ways. One common way is for the atom to absorb a photon of just the right frequency.For example, when white light is shone on an atom, it selectively absorbs those frequencies …
