You may be asked to calculate atomic mass in chemistry or physics. There is more than one way to findatomic mass. Which method you use depends on the information you're given. First, it's a good idea to understand what exactly, atomic mass means. What Is Atomic Mass? Atomic massis the...
andatomic massare two important concepts in chemistry and physics. Many people use the terms interchangeably, but they don't actually mean the same thing. Take a look at the difference between atomic weight and atomic mass and understand why most people are confused or don't care about the d...
这就是说的相对分子质量的事 肯定能翻译过来吧 基本意思就是说 一个氢原子的的质量是碳12原子质量的12分之一，所以氢的相对原子质量为1 镁原子的质量是碳原子质量的2倍，所以镁原子的相对原子质量是24.可能你不知道这个东西：国际规定把一个碳-12原子的质量分为12等份，（碳原子有好几种，其中有...
atomic mass- (chemistry) the mass of an atom of a chemical element expressed in atomic mass units atomic weight,relative atomic mass mass- the property of a body that causes it to have weight in a gravitational field combining weight,eq,equivalent weight,equivalent- the atomic weight of an ...
and the atomic mass are either very close or else the same. In introductory chemistry, it's probably fine to consider them to mean the same thing. However, there are two cases in which the sum of the protons and neutrons (atomic mass number) is not quite the same as the atomic mass!
Video lesson showing how to calculate atomic mass from the naturally occuring isotopes of an element using relative natural abundance and isotopic mass.
2 CHEMISTRY-RELATIVE ATOMIC MASSthe mass of a hydrogen atom 1/1H is equal to 1/12 of the mass of a carbon-12 atomso its relative isotopic mass is 1.A magnesium atom 24/12Mg is twice as heavy as a carbon-12 atom,so its relative isotopic mass is 24再给另一个例子不要用英文角度解释...
combining masses were nearly whole‐number multiples of the combining mass of the lightest element—hydrogen. In 1803, he proposed an atomic theory in which all other elements would be built from multiple hydrogen atoms. Consequently, he based his scale ofatomic masseson hydrogen being equal to ...
