No, protons are about 1836 times heavier than electrons. A proton has a mass of approximately 1 Atomic Mass unit (amu), while an electron has a mass of about 0.0005 amu.
No. An electron is a lot lighter than a proton. A lot as in 1/1836 times lighter than a proton

Why does the number of electrons have little effect on the overal mass of an atom?
Electrons are very light. Protons are approx. 1800 X the mass (rest mass to be presice). Neutrons are about the same mass a protons. So the mass of all the electrons has little effect.
Why is the atomic mass the same as the total number of protons and neutrons in the nucleus?
The atomic mass is the sum of the number of protons and neutrons in the nucleus because protons and neutrons have a mass of approximately 1 atomic mass unit each. Electrons are much lighter and do not significantly contribute to the overall mass of the atom.
Can the mass number be used to determine the number of electrons in an atom?
No, the mass number (number of protons and neutrons) cannot be used to determine the number of electrons in an atom. The number of electrons in an atom is determined by the number of protons in the nucleus, which is the atomic number. Electrons are equal in number to protons in a neutral atom.
Protons and electrons have this?
Protons have a positive electric charge while electrons have a negative charge.
How can the number of proton neutron and electron be calculated to get atomic number and atomic mass?
atomic number is the amount of protons, equal to the atomic number, the electrons, minus the mass number atomic number is the amount of protons, equal to the atomic number, the electrons, minus the mass number atomic number is the amount of protons, equal to the atomic number, the electrons, minus the mass number
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.
When calculating an atoms approximate mass how is the mass of electrons figured?
electrons are the same as protons
What is the atomic mass the same as?
The Atomic Mass is equal to the number of protons and electrons that an element has.
Which other particals have the same mass as protons?
Electrons.
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.
Which two particles have roughly the same mass?
Protons and neutrons have almost the same mass.
The mass of neutrons and electrons are about the same?
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.
Why does the number of electrons have little effect on the overal mass of an atom?
Electrons are very light. Protons are approx. 1800 X the mass (rest mass to be presice). Neutrons are about the same mass a protons. So the mass of all the electrons has little effect.
How does a neutron have same number of protons and electrons?
A neutron does not have the same number of protons and electrons. Neutrons have no charge and are neutral particles that are found in the nucleus of an atom alongside protons. They do not have any electrons associated with them.
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 is the number of protons in the necleus?
# of protons = # of electrons # of protons/ electrons + # of neutrons = atomic mass
Why is the atomic mass the same as the total number of protons and neutrons in the nucleus?
The atomic mass is the sum of the number of protons and neutrons in the nucleus because protons and neutrons have a mass of approximately 1 atomic mass unit each. Electrons are much lighter and do not significantly contribute to the overall mass of the atom.
