The atom is essentially made out of two main components: the nucleus and the electrons. The nucleus is in the centre of the atom whilst the electrons orbit it from a distance. The mass of the electrons is almost negligible, being almost 2000 times smaller than a proton, which is part of the nucleus. The nucleus, whilst having a minute mass, is still many times greater than the electrons. This is why the mass is concentrated in the centre on the nucleus.
What else can I help you with?
Where in the atom is the mass of the atom concentrated?
It is the nucleus. Mass of electrons is too small
Does an atom have center of gravity?
Everything with mass has a center of gravity although in an atomic scale these numbers are very small and in newtons laws state all things with mass put forces on anything else with mass so it might not be possible to balance an atom on top of another atom but everything has a center of gravity that has mass or weight no matter how big or small
Who Ernest Rutherford?
Ernest Rutherford was an investigator of atomic theory, and it was his model of the atom, the one with the mass concentrated in the center, that replaced the J.J. Thompson model. Links are provided below.
Where is most of the atoms mass found?
An atom's mass is concentrated in its nucleus, which is located in the center of the atom. Protons and neutrons within the nucleus are responsible for its mass; the electrons, which are located outside of the nucleus, don't contribute to the mass of the atom.
What determines the atomicity of the elements?
The Atomic Mass number tells the atomic mass of an element. The mass is calculated as the mass of all the protons and neutrons in the center of an atom.
What is the atomic mass of an atom consists of the mass?
the mass of an atom is concentrated in a very small central portion of the atom which is called the atomic nucleus. The atomic nucleus is made up of nucleons, of which there are two important fundamental types: electrically positive protons and electrically neutral neutrons. So the Answer for the question is: Neutrons and Protons.
Most of the mass of an atomic concentrated in the what?
Most of the mass of an atom is concentrated in its nucleus, which is composed of protons and neutrons. Electrons, which have a very small mass compared to protons and neutrons, orbit around the nucleus.
Does an atom of aluminum and an atom of gallium have the same atomic mass?
No, an atom of aluminum and an atom of gallium do not have the same atomic mass. Aluminum has an atomic mass of approximately 26.98 atomic mass units, while gallium has an atomic mass of approximately 69.72 atomic mass units.
How was it proved that the whole mass of an atom is located at its center?
The discovery of the nucleus by Ernest Rutherford in the early 20th century provided evidence that the majority of an atom's mass is concentrated in a small, dense region at the center. Rutherford's gold foil experiment demonstrated that most of the alpha particles passed through the foil undeflected, indicating the presence of a concentrated mass at the center of the atom. This led to the development of the nuclear model of the atom, which suggests that the nucleus contains the majority of an atom's mass.
Where is he mass of an atom concentrated?
99.9% of the mass of an atom is located in the nucleus
What is the mass of an atom concentrated on?
virtually all the mass in concentrated in the nucleus of the atom, as the electron's mass is so small, it is negligible.
Is the number of electrons the same thing as the atomic mass in an atom?
No, electron count really doesn't have anything much to do with atomic mass. Let's look. Most of the mass of any atom is concentrated in the nucleus. It's the protons and neutrons there that give the atom "weight" and the electrons contribute almost nothing. Additionally, electrons can be loaned or borrowed by atoms, and this changes their mass very little. The number of electrons is not very "connected" to atomic mass of an atom.
