In the following sections, we will consider the problems connected with collisions of a radiating atom with atomic particles in external fields that have an influence on the elementary collision event itself. The influence of external fields is of importance for resonance processes where the external...
A. the number of protons in an atom B. the number of neutrons in an atom C. the number of electrons in an atom D. the total number of particles in an atom 相关知识点: 试题来源: 解析 A。元素的原子序数告诉我们一个原子中的质子数。原子序数等于质子数,选项 B 中子数不能由原子序数确...
Further, the atom of an element is made up of three different types of sub-atomic particles namely electron, proton and neutrons. The nucleus of the atom consists of protons which are positively charged and neutral neutrons. Electrons which are negatively charged elements of an atom revolve ...
The atomic number of an atom that has 6 protons, 6 neutrons, and 6 electrons would be 6. This is because the atomic number of an atom is equal to the...Become a member and unlock all Study Answers Start today. Try it now Create an account Ask a question ...
What is the change in atomic mass number when an atom emits an alpha particle? What is an alpha particle the same as? What subatomic particles determine the mass of an atom? What is the alpha particle symbol? How many protons does an alpha particle have? What is the penetrating power of...
one that was much lighter than an atom of the lightest chemical element, hydrogen. These particles were namedelectrons.It was further learned that atoms themselves contained electrons; the electron thus became the first knownsubatomic particle.Since electrons have negative electrical charge, but the at...
