Yes, the atomic weight of the protons and neutrons in an atom (the 2 particles that make up the nucleus) is 1 for each of them. The other particle in an atom is an electron. The atomic weight of an electron is 1/1840 so it is often considered negligible.

∙ 14y agoYes. The mass of subatomic particles are measured by amu, or Atomic Mass units. The nucleus is surrounded by an electron cloud, which contain very light electrons. One electron has a mass of .0005 amu, while a neutron has a mass of 1 amu and a proton has a mass of 1.007 amu. It would take the mass of 2000 electrons to equal the mass of 1 neutron.
Neutrons and protons (the heaviest subatomic particles) are located in the nucleus, which is why most of the mass of an atom is in the nucleus.

Sum of the masses of constituent nucleons is greater than mass of a nucleus The difference is due to?
Energy released during the formation of nucleus and it is equivalent to loss of mass (mass defect).
What are the main points of Rutherford's nuclear model of an atom?
1.Positive charged particle is present at the center of an atom and it is known as the nucleus which consists of the major mass of the atom. 2.The atoms are neutral due to the presence of equal charge of negatively charged electron and positive charged nucleus. 3.The electrons move around the nucleus as the planets move round the sun and the centrifugal force of nucleus is equal to the charge of the moving electrons.
What causes the force thrust?
it is cause mainly due to mass and acceleration
Which has more potential energy an electron close to an atomic nucleus or one far from an atomic nucleus?
In general, electrons farther from the nucleus will have more energy than electrons closer in.
What part of an atom takes up the most space?
Technically, the term particle here is incorrect. The distinction must be made between particle (the things that make up elements and compounds) and sub-atomic particles. (the things that make up elements) In an atom, the sub-atomic particle occupying the most space is the nucleus, containing protons and almost always, neutrons. The rest of it is empty space, save for the orbiting electrons, which are quite tiny in comparison to the nucleus.
Is Most of the mass in an atom is in electrons?
the mass of electrons is negligble the pe rcentage of an atom's mass comes from its protons and neutrons
Why does the nucleus hold almost all of the mass of an atom?
The nucleus consists of neutrons and protons. One neutron or proton is about 1840 times bigger than an electron, which explains the difference of mass between nucleus and the elecrons. When atomic mass is calculated, the mass of the electrons is discounted, due to its relatively insignificant mass.
Where are electrons located in the nucleus?
The electrons are not in the nucleus, they are around the atom in a "probability cloud" due to heisenburgs uncertinty principle.
What does the nucleus of one atom want to do to the electrons of a nearby atom?
The nucleus of one atom wants to attract or pull the electrons of a nearby atom towards itself. This attraction is due to the opposite charges of the protons in the nucleus and the electrons.
How is the structure of an atom of uranium -235 different from the structure of an astom of uranium -238?
Only in the mass of the nucleus, due to 3 extra neutrons in U238.
Why does nucleus of an atom have a positive charge?
an atom has a positive charge due to the fact that it has a positive
All of the mass of an atom is due to the?
The mass of an atom is the sum of the masses of protons, neutrons and electrons.
Atomic mass and atomic weight?
From the New World Encyclopedia, "Technically, atomic mass is equal to the total mass of protons, neutrons, and electrons in the atom (when the atom is motionless), plus the mass contained in the binding energy of the atom's nucleus."Mass number is the number of protons plus neutrons in an atom's nucleus. Mass number varies with individual isotopes due to the fact that atoms of the same element can have different numbers of neutrons.
Why the em value of anode ray depend on the gas?
Actually it is due to the nucleus's. the protons + neutrons) of the individual atoms. Each element (or isotope) have different atomic mass (mainly due to the nuclear mass) and different atomic number (equal to nos of protons in the nucleus). The canal rays (also known as the anode rays are actually the nucleus of the atoms that have been ripped of electrons, hence acquiring an overall positive charge equal to the number of protons in the nucleus of the atom. But since different elements have different mass numbers and atomic numbers hence the e/m ratio varies for the elements canal rays.
What does the charge due to the electrons of a neutral atom do?
balances the charge on the nucleus
Essentially all of the mass of an atom is due to the?
nucleons
Is it true that the necleus of an atom takes up no space compared to the whole atom?
Yes and it is due to the fact that nucleus is compact while electrons form a cloud around nucleus.
