Interpretation: The symbol for each atom is identified. Concept Introduction: Mass number: The sum of protons and neutrons gives the value ofatomic mass. A (mass number) = no.of protons (P) + no.of neutrons (N) The element symbol :ZAXwhere,A (at...
B) Protons and electronsC) Electrons and neutronsD)Electrons, protons, and neutronsAnswer: A 相关知识点: 试题来源: 解析 A 选项A中的质子和中子位于原子核内,构成了原子的主要质量,而电子的质量极小,可忽略不计。原子质量数即质子数与中子数之和。选项B和C错误地包含了电子,而选项D虽然所有粒子都包含,...
An experimental program to investigate the Gerasimov-Drell-Hearn (GDH) sum rule on protons and neutrons has been carried out by the GDH collaboration at MAMI (Mainz) and ELSA (Bonn), using circularly polarized photons and the Bonn-Bochum longitudinally polarized frozen-spin target together with ...
If we separate a nucleus into its nucleons, we would have supply a total energy E called binding energy of that nucleus. The mass of a nucleus is always less than the sum of the masses of its constituent protons and neutrons in their free state. This mass difference is called mass defec...
DIf both assertion and reason is the correct explanation of assertion. Submit Which of the following atom does not contain the same number of protons and neutrons in its nucleus? View Solution Doubtnut is No.1 Study App and Learning App with Instant Video Solutions for NCERT Class 6, Class ...
To solve the question about the sum of the number of neutrons and protons in the isotopes of hydrogen, we can follow these steps:Step 1: Identify the isotopes of hydrogen Hydrogen has three isotopes: 1. Protium (¹H₁) 2. D
The nuclei of elements consists of positively charged protons which repel each other. The strong force is responsible for holding together the protons with the neutrons. The mass of nuclei is always less than the sum of the masses of the protons and neut...
An atom itself is a complete whole, with its electrons, protons and neutrons and other elements.一个原子本身就是一个完整的整体,包括电子、质子、中子及其他元素。 Taken as a percentage of the whole, the mouth has to be a fairly minor body part. 和全身比起来,嘴可算是身体中较小的一部分。
At present, the model that is used to describe an atom is the electron cloud model. This model contains three subatomic particles known as protons, neutrons, and electrons. We can divide the atom into two sections composed of an electron cloud and a nucleus. Electrons ...
Nuclear radial matter density distribution Model-independent Sum-of-Gaussians (SOG) method Elastic proton scattering in inverse kinematics Doubly magic radioactive 56Ni nucleus The radial matter density distribution of the nucleus and the share of matter density between protons and neutrons are among th...
