There is nothingwith a mass of exactly 1 a.m.u.
The a.m.u. is defined by Carbon 12 having exactly 12 a.m.u s, and it is the only isotope with an exactly integral number of them.
Having said that, Hydrogen is pretty close to 1 a.m.u.

What is the electron mass an atom?
an electron is about 1/1836 amu.
What has a mass of 0 amu and a charge of -1?
The electron has a charge of -1; but the electron has a mass.
What is the atomic mass unit for neutron and electrons?
The atomic mass unit is approximately the mass of one neutron or proton. An electron has a mass of approximately 1/2000 of an amu.
How many amu's are in a kg?
the amu of potassium is 39.0983
If an atom has 8 neutrons and a mass of 15 amu how many proton and electron are present in this atom?
It would have 7 protons It woul have 7 electrons
What is the AMU of a Electron?
1
What is the electron mass an atom?
an electron is about 1/1836 amu.
What are the mass and charge for each sub-atomic particle?
In the atom: Neutron: Mass: 1,00866491600(43) amu. Electron: Mass: 5,4857990946(22)×10−4 amu. Proton: Mass: 1,007276466812(90) amu.
Is the mass of a single electron one mass unit?
No, it's about 1/2000th of an amu (atomic mass unit). Protons and neutrons are 1 amu.
How many amu's are in one gram?
The equivalent is 0,6.10e24 amu.
What unit is designated by amu?
Electron cloud
What subatomic particle does not make a significant cintribution to the mass of an atom?
The electron - both neutrons and protons weigh one amu, but the mass of an electron is negligible.
What is the mass in AMU's of an electron?
1 over 1,836 AMUAnother answerIt's negligible. It has such a low amu that it is not a factor of the overall atomic mass of an atom
What is the mass of each particle?
Proton: 1.007276466812(90) amu. Neutron: 1.00866491600(43) amu. Electron: 5,857990946(22)×10−4 amu.
Mass number of an electron?
The mass number of an electron is 5.485 799 095 x 10-4 amu.
What is the atomic mass unit for neutron and electrons?
The atomic mass unit is approximately the mass of one neutron or proton. An electron has a mass of approximately 1/2000 of an amu.
What is the mass of the 3 subatomic particles?
Neutron: Mass: 1,00866491600(43) amu. Electron: Mass: 5,4857990946(22)×10−4 amu. Proton: Mass: 1,007276466812(90) amu.
