the number of electrons in an atom我应该怎么回答?题目有给出些元素和他们的原子序数 相关知识点: 试题来源: 解析 对中性原子来说,电子数等于电子序数.对离子来说,原子序数等于电子数加电荷数(阳离子)或电子数减电荷数(阴离子). 分析总结。 对离子来说原子序数等于电子数加电荷数阳离子或电子数减电荷数阴离...
atomic number of an element 指的是:元素X的原子序数是15,核外有15个电子,所以该元素为P元素,即磷元素而number of electrons in an anion of X问得是:X元素的阴离子核外电子数是多少?因为P的最外层电子是5个电子,所以必须得到3个电子才满足8个电子的饱和结构所以磷元素的阴离子核外电子数是:15+3=18所...

The further away from the nucleus an electron shell is located, the more sublevels, orbitals, and electrons it can hold. This is because these shells have higher energy levels.Answer and Explanation: The maximum number of electrons that can be contained in the n=3 level is 18. This ...
Step 2:If it is an ion, determine the charge of the ion. This can be seen in the name of the ion. Mg2+ +2 Step 3:Determine the number of electrons: If it is a neutral atom, the number of electrons is equal to the proton number ...
To solve the question of which species has the same number of electrons in its outermost and penultimate shell, we will analyze each of the given species: Mg²⁺, O²⁻, F⁻, and Ca²⁺.Step 1: Understand the Definitions</
