What number tells the mass of the nucleus of an atom?
The atomic mass number is the mass of the nucleus in atomic mass units.
What is the mass of a hydrogen nucleus?
The mass of a hydrogen nucleus is approximately 1 atomic mass unit.
Lost of an atoms mass is in the nucleus?
Almost all of an atom's mass is in the nucleus.
Is most mass in the nucleus?
Yes, the great majority of the mass of an atom is in the nucleus.
Where in the atom is the mass of the atom concentrated?
It is the nucleus. Mass of electrons is too small
The nucleus makes up 99 percent of the atoms what?
The nucleus makes up nearly all of the mass of an atom, with over 99% of its mass concentrated in the nucleus. Within the nucleus, most of the mass is found in the protons and neutrons, while the electrons surrounding the nucleus contribute very little to the overall mass.
How does the mass of the nucleus compare to the mass of the electron?
The nucleus is far more massive than the electron cloud. The mass of the electron cloud is almost negligible compared to that of the nucleus.
Why do the mass of atom depend upon the nucleus?
The mass of an atom depends on the nucleus because the nucleus contains the majority of the atom's mass in the form of protons and neutrons. Electrons, which orbit the nucleus, have a much smaller mass compared to protons and neutrons. The mass of an atom is essentially the combined mass of its protons and neutrons in the nucleus.
How does the mass of the nucleus compared to the mass of the Atom?
The mass of the nucleus makes up most all of the mass of an atom. The only things outside the nucleus are the electrons. The mass of an electron is ~9.11E-31 kg. The mass of an electron is 1/1836 that of a proton.
The majority of the atom's mass is found in the?
The majority of an atom's mass is found in the nucleus, which contains protons and neutrons. Electrons, which are much smaller in mass, are located in the electron cloud outside the nucleus.
Mass number of nucleus?
The Mass Number is the number of protons plus the number of neutrons in the nucleus.
In the atom nearly all the mass is found in the what?
An atom is comprised of protons, neutrons, and electrons. The electrons take up the most space as they orbit the nucleus. But nearly all of the mass of the atom is found in the nucleus of the protons and neutrons.
