The answer to ‘what is atomic mass’ is this: the total mass of the protons, neutrons, and electrons in a single atom when it is at rest. This is not to be associated or mistaken for atomic weight. Atomic mass is measured by mass spectrometry. You can figure the molecular mass of a...
If the atomic mass number is composed of neutron and protons then surely the amu of an atom should be a whole number as neutrons and protons both have a mass of +1. For example, should not sodium have an amu of 23? Why does chlorine have an amu of 35.45?
Mass Number It is the sum of neutrons and protons of an atom present in nucleus. Mass Number for two different atoms can be same. The Atomic Mass of an atom is approximately equal to its Mass Number as mass of a neutron as well of a proton is one unit on atomic mass scale.Email...
All elements in the periodic table are made of subatomic particles. These are protons, neutrons and electrons. The protons and neutrons are found in the centre of the atom, which makes up the atomic nucleus.Answer and Explanation: Become a member and unlock all Study Answers Try it risk-...
Matter has mass and takes up space. Atoms are basic building blocks of matter, and cannot be chemically subdivided by ordinary means. Atoms are composed of three type of particles: protons, neutrons, and electron. Protons and neutrons are responsible for most of the atomic mass, e.g in a ...
Which element has an atomic number of 76? Which element has an atomic number of 12? Which element has atomic number 19? Which element has atomic number 20? Which element has the atomic number 43? What is the atomic mass of an atom that has 6 protons, 6 neutrons, and 6 electrons?
Therefore, any attempt to divide the nucleus into the same number of free unbound neutrons and protons – so that they are far/distant enough from each other that the strong nuclear force can no longer cause the particles to interact – will require enough energy to break these nuclear bonds...
The atomic mass is the mass of an atom. Although the SI unit of mass is the kilogram, the atomic mass is often expressed in the non SI-unit dalton, where one dalton is defined 1/12 of the mass of a single carbon-12 atom, at rest. The protons an...
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...
Atomic Mass of Iron An element's atomic mass is equal to the sum of the individual particle masses of an atom. Atoms have three basic particles which include protons, neutrons, and electrons. The standard unit for measuring atomic mass is the Dalton (u). ...
