The mass number (symbol A, from the German word Atomgewicht [atomic weight]), also called atomic mass number or nucleon number, is the total number of protons and neutrons (together known as nucleons) in an atomic nucleus. It is approximately equal to the atomic (also known as isotopic) mass of the atom expressed in atomic mass units. Since protons and neutrons are both pool how to raise ph

Web12 de abr. de 2024 · It has been given that a nucleus with mass number A = 27 has a radius equal to 3.9 f e r m i. Thus, when R = 3.9 f e r m i and A = 27, 3.9 = R 0 ( 27) 1 / 3 ⇒ R 0 = 3.9 3 = 1.3 Now, it has been given that, A = 125, and we have calculated that, R 0 = 1.3. We substitute these values in the equation to find the radius of a nucleus, R = R 0 ( … WebThe given element is having 14 nutrons and 27 mass number means number of electrons or protons are (z−n) 27−14=13 each. Distribution of electrons according to 2n 2 (n = principal quantum number) is 2(K),8(L),3(M). Hence, the valence shell of this element is M. Solve any question of Structure of Atom with:-.
