No. The mass of neutrons and protons are about the same. The mass of an electron is about 1/1800th the mass of a proton.

Do protons nuetrons and electrons all have about the same mass?
Protons and neutrons have about the same mass, but electrons are much, much lighter.
Which two particles have roughly the same mass?
Protons and neutrons have almost the same mass.
Isotopes have the same element but different?
Isotopes of the same element have the same number of protons and electrons, but varied numbers of neutrons.
Why is the atomic mass the same as the total number of protons and neutrons in the nucleus?
The neutrons and protons are in the nucleus which determines the element/isotope. The electrons however define the net charge (ie. positive if there are less electrons then protons and negative if more) and it can be changed more easily, than changing the amount of neutrons . Another reason is that electrons have a tiny mass compared to the protons and neutrons and it wouldn't change the mass number by all that much.
Neutrons and what almost have the same mass?
A neutron and a proton almost have the same mass. A neutron and 1,840 electrons almost have the same mass.
How do you find the mass number given the proton electrons and atomic number but not the neutrons?
The mass number of an atom is the number of protons plus the number of neutrons. This is is the same as the number of electrons plus the number of neutrons since the number of protons is the same as the number of electrons in an atom.
Do neutrons have same mass as electrons?
No, protons and neutrons both have a relative mass of 1. Whereas, electrons have a relative mass of (1x10^-5), which is the equivilent to saying that an electron's mass is about 100,000 times smaller than a proton or neutron.
What is the atomic mass and symbol of an element with 34protons 33 neutrons 34 electrons?
The 34 protons means that this is the element that has an atomic number of 34, which is selenium. The mass number for the isotope given is 67, which is the sum of the protons and neutrons. Mass number is not the same as atomic mass. Atomic mass is the total mass of the protons, neutrons, and electrons in an atom.
How many protons neutrons and electrons does Ca have?
Electrons have no relevant mass, and protons and neutrons both have the mass of 1u. If Calcium has the number 20, it has 20 protons (and electrons). It's mass is about 40u. Core Mass - Protons = Neutrons 40u - 20u = 20u, this means Calcium has 20 electrons, 20 protons and 20 neutrons.
Is the mass number equal to the number of protons and electrons?
No, it isn't. The mass of an electron is significantly smaller than that of a proton.The mass of 1,800 electrons is about the same as the mass of one single proton.The antiparticle of the electron, the positron, has the same mass as the electron.the mass of the electron is not the same to the mass of the proton
What statement is true about atoms protons neutrons and electrons?
Several come to mind. They are both found in the nucleus of an atom. Protons have a positive charge, while neutrons have no charge. They are nearly the same size, though neutrons are a bit larger. The sum of the protons and neutrons in an isotope of an element is its mass number.
The neutrons in an atom have the least amount of mass?
No actually, the neutrons and the protons of an atom are relatively the same in mass. Electrons have the smallest mass in an atom, and are not even considered when we look at the mas sof an atom.
