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
Atomic mass of an atom is determined by the weight of?
The atomic mass of an atom is determined by the total number of protons and neutrons in its nucleus. Protons and neutrons contribute to the majority of an atom's mass, electrons have negligible mass in comparison. The atomic mass unit (amu) is used to express atomic mass, with 1 amu approximately equal to the mass of a proton or neutron.
What is one twelfth of the mass of the carbon 12 atom?
the answer is the atomic mass unit
Are electrons negatively charged and have a mass of 1 amu?

What sub-atomic particles have a mass of 1 amu?
neutrons and protonsbut NOT electrons (the almost have no mass)
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
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 number of neutrons mass atomic protons electrons in tritium?
1 proton 1 electron 2 neutrons mass = 3 amu
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.

How many atoms are in 1 amu?
There is no fixed number of atoms in 1 atomic mass unit (1 amu) because an atomic mass unit is a unit for measuring the mass of an individual atom. The mass of an atom is determined by the total number of protons, neutrons, and electrons it contains.
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 two subatomic substances have a mass of about 1 amu?
The proton an neutron both have a mass of about 1 amu. (Both have a mass just slightly above 1 amu, and the neutron's mass is slightly larger than that of a proton.)
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.
