When calculating an atomic approximate mass how is the mass of electron figured?
When calculating the atomic mass of an atom, the mass of an electron is typically considered negligible. This is because the mass of an electron is almost 2000 times smaller than the mass of a proton or neutron, which are the primary components used in determining the atomic mass of an atom.
Which of the following particles is used to determine the mass of an atom?
Mass of an atom is determined by the no. of protons+ no. of neutrons in the atom.
Why are electrons not used to determine the mass number or atomic mass of atoms?
because
Is the smallest particle used to build a molecule called an atom?
Yes and no. See, the atom is made up of three types of particles. Inside the atom is the Proton (+) the neutron (neutral) and the electron (-). The electron is by far the smallest. There are other, smaller particles that also exist inside atoms, but judging by the question, the electron is definitely the smallest you need to worry about. Its mass is something like 10^-31 kg.
What is used to find the mass of an atom?
The mass of an atom is obtained dividing the atomic weight of an isotope by the Avogadro number.

What part of an atom is not used in calculating the mass number?
All parts of the atom weigh something but when doing calculations electrons are said to have a mass of 0. This is because they actually have a mass of 1/1836 amu which is insignificantly small and so it is disregarded.
What part of an atom is used to tell how one atom will bond with another atom?
Electron
Which of the following particles is used to determine the mass of an atom?
Mass of an atom is determined by the no. of protons+ no. of neutrons in the atom.
What particles are used to determined the mass of an atom?
Mass of an atom = mass of protons + mass of neutrons
Mass number used to calculate the number of?
The mass number is used to calculate the number of nucleons in an atom. It represents the sum of protons and neutrons in the nucleus of an atom. By knowing the mass number, one can determine the approximate atomic mass of the atom.
Why are electrons not used to determine the mass number or atomic mass of atoms?
because
What is He2s1?
He2s1 is a chemical notation for a helium atom that has one electron in the 2s subshell. This notation is commonly used to represent the electron configuration of an atom.

What unit is designated by amu?
The unit designated by amu stands for atomic mass unit. It is used to express the mass of atoms and molecules on a very small scale, equivalent to one twelfth of the mass of a carbon-12 atom.
Why electrons have no mass?
They have mass, it is just too little in comparison to the mass of the neutron and protons to be taken into account. Therefore when measuring the mass of an atom, the mass of the electron are not used. (To be exact,9.10938188 × 10-31 kilograms, and the mass of proton is 1.67262158 × 10-27 kilograms.)
What is used to find the mass of an atom?
The mass of an atom is obtained dividing the atomic weight of an isotope by the Avogadro number.
