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 are the sizes of portons neutrons and electrons?
Protons and neutrons, which are found in the nucleus of an atom, have masses of approximately 1 atomic mass unit (amu), with protons having a mass of about 1.007 amu and neutrons about 1.008 amu. Electrons are significantly smaller, with a mass of about 0.0005 amu, or roughly 1/1836 of a proton's mass. In terms of size, protons and neutrons are roughly 1 femtometer (10^-15 meters) in diameter, while electrons are often considered point-like particles with no defined size.
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.
Draw and label the parts of a helium atom. Include the mass and charge pf each subatomic particle.?
A helium atom consists of two protons and two neutrons in its nucleus, surrounded by two electrons in orbitals. Protons have a mass of approximately 1 atomic mass unit (amu) and a charge of +1, while neutrons also have a mass of about 1 amu but carry no charge. Electrons have a negligible mass (approximately 1/1836 amu) and a charge of -1. Thus, the overall charge of a neutral helium atom is zero, balancing the positive charges of the protons with the negative charges of the electrons.
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 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.
