How many protons, electrons, and neutrons are in I- and Li+
WebArgon has 26 known isotopes, from 29 Ar to 54 Ar and 1 isomer ( 32m Ar), of which three are stable ( 36 Ar, 38 Ar, and 40 Ar). On the Earth, 40 Ar makes up 99.6% of natural argon. Argon-36 is composed of 18 protons, 18 neutrons, and 18 electrons. Argon-38 is composed of 18 protons, 20 neutrons, and 18 electrons. Web10 mei 2024 · Using the average atomic mass, calculate the average number of neutrons by first rounding the atomic mass from 200.592 to 201. Now, subtract the number of protons, 80, from the atomic mass, 201-80, to find the average number of neutrons, 121. If the mass number of an isotope is known, the actual number of neutrons can be calculated. port forwarding steps
