What else can I help you with?
Do electrons neutrons and protons have essentially the same mas?
No, Protons and Neutrons have similar masses, but one electron is equal 1/1836 of a proton in mass.
How do the masses of the protons and the neutrons compare to the mass of the electrons?
If we give them relative numbers, the proton has a mass of 1.0073, the neutron has 1.0087 and the electron has 5.486 X 10 to negative 4.
How do the masses of electrons compare with the masses of protons?
The mass of a proton is 1836 times greater than the mass of an electron.
How many protons and neutron and electron and nucleus electron cloud are the in curium?
Curium has 96 protons. Number of neutrons = Atomic mass of an isotope - atomic number of the isotope The atomic number of curium is 96; for the isotopic masses of curium read at the link below.
Are protons larger than neutrons?
Neutrons have greater mass. A neutron rest mass is 1838 electron volts. A proton rest mass is 1835 electron volts. In terms of physical size, this question may not be meaningful. Protons and neutrons are comprised of three quarks each, and their masses apparently are not conserved.
Is the is the sum of the numbers of protons and neutrons in an isotope of the element?
Isotopes involve different atomic masses. It is sum of number of protons and neutrons.
Which particles determine the mass of an atom?
The atomic mass unit is defined to be 1/12 of the mass of a carbon-12 atom. Atomic masses can determined by weighing molar amount of an isotope. Absolute masses (in kg) are determined by measuring the amount that charged atoms are deflected by magnets, since if you know the charge you can calculate mass from the amount of deflection.
What are the masses of each subatomic particle?
protons and neutrons are about 1 amu
What are atoms of an element that make different atomic masses?
protons and neutrons
What The atomic mass of an atom equals the sum of the masses of the?
Protons and neutrons.
What do neutrons and protons have common?
The atomic nucleus contains neutrons and protons (apart from hydrogen-1 which only has 1 proton and no neutrons). The difference between them is that protons have a positive charge and neutrons have no charge. They also have slightly different masses.
What neutrons and protons have in common?
