∙ 13y agoClose enough. Neutrons actually have a mass VERY slightly higher than a proton, but both are considered to be one amu in mass.
Wiki User
∙ 10y agoNo, they have a mass of approximately 1/1836 amu.
Wiki User
∙ 11y agoThe mass of the electron is 5,485799094 6(22)×10−4 amu.

∙ 12y agoNo. It takes more than 1,800 electrons to make 1 AMU.

Are electrons negatively charged and have a mass of 1 amu?
Electrons do have a net charge of negative one. Their mass, however, is only a fraction of 1 atomic mass unit, specifically, 1/1836 amu.
When it loses two electrons to become a calcium ion what is it's new mass?
38 amu EDIT: This answer is INCORRECT. Electrons do not have significant mass.
When an atom loses an electron the mass of the at om?
The mass doesn't change because electrons are so light that its mass is not included in the AMU.proton = 1 amuneutron = 1 amuelectron = ~1/1837 amu
What is one twelfth of the mass of the carbon 12 atom?
the answer is the atomic mass unit
What does a.m.u stand for?
Atomic mass unit. Unit for mass for atoms & their sub-atomic particles. An electron is rounded to 0 amu (since its mass is less than 1 amu). A proton and a neutron are 1 amu each.
Are electrons negatively charged and have a mass of 1 amu?
Electrons do have a net charge of negative one. Their mass, however, is only a fraction of 1 atomic mass unit, specifically, 1/1836 amu.
What sub-atomic particles have a mass of 1 amu?
neutrons and protonsbut NOT electrons (the almost have no mass)
Atomic weight of electrons in h2o?
Negligible. The mass of an electron is around 1/1840 of an amu, so the 18 electrons in a water molecule contribute a little under 0.01 amu to the total mass of the molecule.
What is the amu of a proton?
One proton (at rest) has a.m.u. of 1.007276 which is 1.67262*10-27 kg
What is the number of neutrons mass atomic protons electrons in tritium?
1 proton 1 electron 2 neutrons mass = 3 amu
How many electrons equal the mass of one Proton?
1836 electrons equal the mass of 1 proton. A proton has a mass of 1.0073 amu, a neutron 1.0087 amu, and an electron 5.486 x 10-4. So, it would take 1836 electrons to equal the mass of 1 proton.
When it loses two electrons to become a calcium ion what is it's new mass?
38 amu EDIT: This answer is INCORRECT. Electrons do not have significant mass.
How do you identify the relative mass the relative charge and location of the three smaller subatomic particles of an atom?
protons --- rel. mass 1 amu, rel. charge +1, location in the nucleus. neutrons --- rel. mass 1 amu, rel. charge 0, location in the nucleus. electrons --- rel. mass 0 amu, rel. charge -1, location outside the nucleus.
How do you identify the relative mass relaitive charge and location of the three smaller subatomic particle of an atom?
protons --- rel. mass 1 amu, rel. charge +1, location in the nucleus. neutrons --- rel. mass 1 amu, rel. charge 0, location in the nucleus. electrons --- rel. mass 0 amu, rel. charge -1, location outside the nucleus.
When an atom loses an electron the mass of the at om?
The mass doesn't change because electrons are so light that its mass is not included in the AMU.proton = 1 amuneutron = 1 amuelectron = ~1/1837 amu
What is the amu of electrons?
1/1837
Is Most of the mass in an atom is in electrons?
the mass of electrons is negligble the pe rcentage of an atom's mass comes from its protons and neutrons
