To solve the problem, we need to determine the number of electrons, protons, and neutrons in an atom of an element with an atomic weight of 52 and an atomic number of 24.1. Identify the Atomic Number: The atomic number (Z)
Moreover, elements with heavier atomic mass were naturally more decoupled and unpredictable in space than those with lighter mass. Only the coupling of carbon, nitrogen and phosphorus, which are essential to life on Earth, deviated from this predictable pattern, suggesting that this anomaly may be...
6 (a) An element X has an atomic number of 24 and a relative atomic mass of52.06. The natural element consists of four isotopes. The mass spectrum of the element X produced the following peaks of three of the isotopes on the chart recorder.Percentage83.804.302.4050 51 52 53 54 55 56 ...
An element X with an atomic mass of 60 g/mol has density of 6.23gcm−3. If the edge length of its cubic unit cell is 400 pm, identify the type of cubic unit cell. Calculate the radius of an atom of this element. View Solution A element X with atomic mass 60 g/mol has a de...
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,但电子贡献微乎其微,因此正确答案为A。反馈 收藏

along with martensitic transformation8. The prerequisite for work hardening is dislocation production and accumulation. However, the higher the yield strength, the more difficult it will be to produce and even store dislocations in microstructures. This becomes pronounced particularly in alloys with an ...
