The number 31 represents the mass number, which is the sum of protons and neutrons in the nucleus ...A represents the isotope’s mass number and symbol Z represents the isotope’s atomic number. All isotopes of an element have the same number of protons and electrons, which means they exhibit similar chemical properties. (credit: “ 1.6 Isotopes and Atomic Masses” In Principles of General Chemistry (v. 1.0) by Anonymous, CC BY-NC-SA 3.0 ... ...
Elephant gun | Jan 30, 2023 · As mentioned before, isotopes are atoms that have the same atomic number, but different mass numbers. Isotopes are denoted the same way as nuclides, but they are often symbolized only with the mass numbers because isotopes of the same element have the the same atomic number. Carbon, for example, has two naturally occurring isotopes, 126 C 6 12 ... When speaking of different isotopes, a special kind of notation is used: 14C 6 Here, the superscript number is the mass nu mber, or the total number of neutrons and protons present in the atom. The subscript number is t he atomic number, or the number of protons in the nucleus. Other ways to write this same isotope include: 14C Carbon - 14 So the notation for this isotope of carbon would look like this. We have the chemical symbol C with the mass number 12 written at its top-left, and the atomic number 6 written at its bottom-left. But for the isotope with 6 protons and 7 neutrons, the mass number would be 6 plus 7, or 13. So the notation for the carbon isotope would be as follows. ...
Spirit in the sky | Two isotopes of carbon, namely carbon 12 12 and carbon 13 13 , are chosen to illustrate their composition. Carbon 12. Carbon 13. A/Z isotope notation.This is why radioactive isotopes are dangerous and why working with them requires special suits for protection. The isotope of carbon known as carbon-14 is an example of a radioisotope. In contrast, the carbon isotopes called carbon-12 and carbon-13 are stable. This whole discussion of isotopes brings us back to Dalton's Atomic Theory....
