网络电子式;点叉式 网络释义
Dot and Cross Diagram,即点叉图,是一种用于表示离子或共价化合物或元素中外层电子排列的图示方法。在这种图示中,电子用点(dot)和叉(cross)来表示。点叉图主要用于化学领域,帮助学生和研究者直观地理解分子或离子的电子结构。 Dot and Cross Diagram的用途和应用场景 Dot and C...
Nitric acid, HNO3, is a fascinating molecule because it has an unusual set of covalent bonds. Which of the following dot-and-cross diagrams correctly depicts how bonding electrons are arranged in nitric acid molecules? A covalent bond forms when two nonmetal atoms share one or more pairs of ...
铵离子是由一个氮原子和四个氢原子组成的,其中一个氢原子与氮原子形成离子键,其余三个氢原子与氮原子形成共价键。氮原子有5个外层电子,但作为铵离子,它失去了一个电子,所以只有4个外层电子参与成键。每个氢原子有1个外层电子。在铵离子中,氮原子的4个外层电子与4个氢原子的4个外层电子形成4个共价键。 铵...
