1,电子与电荷电子是物质的一种基本粒子,是绕原子核高速运转的带有最小负电荷的粒子:电荷的概念是人们对电的一种传统认识.在古代,人们因不了解电的本质,认为电是附着在物体上的,因而把电称为电荷.物体“带了电”与“带了电荷”是同一个意思.实际上,现在人们所说的电荷,一般是指带电的物质微粒,是带电微粒的总称,分为正电荷(如原子核、质子、正离子)与负电荷(如负离子、电子).显然电荷这一概念的范围要比
1. Electrons and Charges Electrons are a kind of basic particles of matter and they are the particles with the lowest negative charges running around the nucleus at high speed: the concept of charge is a traditional knowledge of people in electricity.In ancient times, people did not understand the electricity The essence is that the electricity is attached to the object, so the electricity is called the electric charge. The object “with the electric ” has the same meaning as the “charged” In fact, what people call the electric charge Is charged material particles, is a general term for charged particles, divided into positive charges (such as nuclei, protons, positive ions) and negative charges (such as negative ions, electrons). Clearly the concept of charge range than
