Also, I thought atomic weight meant the sum of the number of protons and the number of neutrons but I found out that is called the mass number. So how do we find the number of neutrons from a periodic table? Can we simply subtract the atomic weight/atomic mass/ atomic relative mass by...
D. The students were in a hurry. 相关知识点: 试题来源: 解析 A。解析:测量物质质量不一致可能是因为天平没有正确校准,A 选项正确。B 选项物质颜色亮不会影响质量测量。C 选项实验室冷一般不会对质量测量产生直接影响。D 选项学生匆忙可能会导致操作不规范,但不一定直接影响质量测量结果。
Atomic mass (ma) is the mass of an atom. Asingle atomhas a set number of protons and neutrons, so the mass is unequivocal (won't change) and is thesum of the number of protonsand neutrons in the atom. Electrons contribute so little mass that they aren't counted. ...
