Why don't we use the mass of the electron to get the atomic mass of an element?

The number of electrons are variable for an element because electrons can be lost or gained. Additionally, the mass of an electron is so much smaller than the mass of neutrons and protons that it can be considered negligible for most purposes.

What subatomic particle has a mass that is so small it's not counted in the atomic mass of that element?
Electron
What information is included in each square of the periodic table of elements?
Each column will generally have the symbol of the element (sometimes name of the element also), the atomic number, the mass number, the state in which the element is present at room temperature. Some periodic table will also have the electronic configuration or electronegativity.
What is the average atomic mass of the element y?

Is there an element that has the same atomic number and atomic mass?
No, there is no naturally occurring element with the same atomic number and atomic mass. The atomic mass of an element is the weighted average of the masses of its isotopes, which have different numbers of neutrons. The atomic number of an element is the number of protons in its nucleus, which determines its identity. Therefore, the atomic number and atomic mass are different for each element.
What does the atomic mass of an electron represent?
The mass of an electron is atomic mass units is 5,485 799 090 70(16); the mass of the electron is not an atomic mass.
Why is the mass of an element not added to the atomic mass of an atom?
Because the electron is a lepton, and is not made of quarks.

What is the mass of 1 electron?
1/1836 of an electron is the mass of an electron. It is so small they aren't even calculated in the Atomic Mass of an element
What is an electron's atomic mass number?
The electron has no atomic mass number. The mass of an electron is roughly 1/1800 of the mass of a proton or neutron.
How many atomic mass do krypton have?
47 neutron and 36 proton and 36 electron because its atomic number is 36.
What four pieces of information about each element is found on the periodic table?
Well the four main types really go down to the Atomic Number, Atomic Mass, The Chemical/Atomic symbol, and the elements name of course. But different tables vary.
What is the atomic mass for magnesiam?
Magnesium is a meta element. Atomic mass of it is 24.
What is the atomic mass or weight of an electron?
electron mass = 9.10938188 × 10-31 kilograms = 0.000548579867 atomic mass units
