Izotónokat
Izotónokat are atoms of different chemical elements that have the same number of neutrons. This means they have different atomic numbers and mass numbers, but their neutron count is identical. For example, potassium-39 (19 protons, 20 neutrons) and calcium-40 (20 protons, 20 neutrons) are izotónokat because they both contain 20 neutrons. The term "izotónok" comes from the Greek words "isos" meaning equal and "tonos" meaning tension or strength, referring to the equal number of neutrons. While isotopes have the same number of protons and vary in neutrons, and isobars have the same mass number and vary in protons and neutrons, izotónokat specifically focus on the equality of neutron count across different elements. This concept is relevant in nuclear physics and chemistry for understanding nuclear stability and reactions. The properties of izotónokat are generally distinct due to their different elemental identities, though their nuclear behavior can share some similarities owing to the shared neutron number.
