However, isotopes vary in the number of neutrons in their nuclei.Answer and Explanation: The formula for mass number is simple: Mass number = protons + neutrons This is because a mass number is the total count of protons and neutrons in...Become a member and unlock all Study Answers St...
Keep in mind that A=Z+N, where N is the number of neutrons. Due to mass-energy conservation laws during decay, the unstable parent and the result daughter nuclides are related by their atomic mass numbers A and atomic numbers Z. So, The parent's atomic number must be equal to the ...
What is the electronegativity of fluorine? What is the chemical formula for fluoride? What do fluorine and chlorine have in common? What is the number of neutrons in fluorine? How many bonds can fluorine form? How many atoms are in 1.50 moles of fluorine gas?

(a) They can denote an atom of the element. For example, Cl can denote a chlorine atom having 17 protons and 18 or 20 neutrons (giving a mass number of 35 or 37), the difference being ignored. Its mass is on average 35.4527 u in terrestrial samples. (b) The symbol may, as ...
摘要: It is shown that the experimental results on negaton and proton scattering by nuclei are in agreement with the assumptions that the central density of nuclear matter is constant for all nucleides and that the neutron and proton distributions in a nucleus are the same.关键词:...
Because all the atoms that make up an element have the same number of protons but sometimes differ in their number of neutrons, some of the atoms of the element will vary in mass. This results in the weighted average sometimes having fractions of an atomic mass unit. For example, fluorine...
Implementation of Gy-Eq for Deterministic Effects Limitation in Shield Design The NCRP has recently defined RBE values and a new quantity (Gy-Eq) for use in estimation of deterministic effects in space shielding and operations. The N...
