The mass number of argon is 40.How many protons, neutrons and electrons are there in an argon atom? ( ) 相关知识点: 试题来源: 解析 一个氩原子有 18 个质子、22 个中子和 18 个电子。 1. 原子序数: 氩的原子序数为 18,这意味着它的原子核中有 18 个质子。 2. 质量数: 氩的质量数为 40...
GeV photon beams are provided at SPring-8/LEPS facility by backward-Compton scattering (BCS) from Argon laser photon against the 8-GeV electrons inside the SPring-8 storage ring. The energy range of tagged photon by measuring the recoil electron is from 1.5 to 2.4 GeV, and enables us to ...
