Web1) Calculate the percent abundance for each isotope: X-12: 100/110 = 0.909 X-14: 10/110 = 0.091 2) Calculate the average atomic weight: x = (12.00) (0.909) + (14.00) (0.091) x = 12.18 amu (to four sig figs) 3) Here's another way: 100 atoms with mass 12 = total atom mass of 1200 10 atoms with mass 14 = total atom mass of 140 WebAug 5, 2024 · Aug 5, 2024 The isotope symbol for helium-3 is 3 2He. Explanation: Helium-3 contains 2 protons and 1 neutron. Here's the general formula to write isotope symbols A BC A Represents the mass number B represents the atomic number C Represents the element symbol Answer link
Write isotopic symbols in the form X-A (e.g., C-13) for each isotope…
WebIsotopes are atoms that have the same numbers of protons but different numbers of neutrons. An ion is an atom that has gained or lost electrons, so it now has more or fewer electrons than it does protons. So an ion has a negative or positive charge. All atoms are isotopes and if an isotope gains or loses electrons it becomes an ion. WebJul 29, 2024 · An isotope of any element can be uniquely represented as AZX where X is the atomic symbol of the element. The isotope of carbon that has 6 neutrons is therefore 126 C The subscript indicating the atomic number is actually redundant because the atomic symbol already uniquely specifies Z. grandstream telefoon
