1.解元素推断题必用的重要关系(1)围绕ZAXn(n为化合价数)的有关关系①核电荷数(z)=原子序数=核内质子数=核外电子数(n=O时) ②质量数(A)=质子数(z)+中子数(N)
1. The important relationship that must be used to solve the element deduction (1) The relationship around ZAXn (n is the valence number) 1 Nuclear charge number (z) = Atomic number = Nuclear proton number = Nucleus electron number (n = O) 2 mass number (A) = number of protons (z) + number of neutrons (N)
