WebApr 20, 2024 · We can use tools like the periodic table of elements to figure out exactly how many protons, and thus electrons, an atom has. First of all, we know that for an atom to have a neutral charge, it must have the same number of protons and electrons. If an atom loses or gains electrons, it becomes ionized, or charged. WebApr 24, 2015 · In a collision, the gas molecule can absorb some energy from the electron and undergo an electronic excitation, which is short-lived. When the molecule relaxes or de-excites, it emits a photon of light. The light is blue because this matches the spacing between two energy levels in nitrogen. graphene in food https://lagycer.com
