This can refer to either the nucleus or to an individual proton that makes up the nucleus. Because only protons and neutrons occupy the nucleus, it has a positive charge.
Nucleus. Discovered by Ernst Rutherford in the Gold Foil (Alpha Scattering) Experiment.
No, it is a noun. It may refer to the mass center of an atom, or to the structure at the center of many living cells.
In Rutherford's gold foil experiment, some of the Alpha particles aimed at gold atoms bounced back, suggesting that a solid mass was at the center of the atom.They suggested that most of the mass of the atom is concentrated at the center and the center is positively charged.
At the center of an atom we will find the nucleus of the atom. There, we'll find protons and neutrons (except "common" hydrogen, which has a single proton for a nucleus). For more information on the nucleus of the atom, see the related question below. The dense part of the atom which can usually be 'called' its center is the nucleus - which has charged (electrical) protons and neutrons (electrically neutral) those are surrounds by look-like 'cloud' called electrons.The center core of an atom is called the nucleus. It consists of the neutrons and protons.
The most mass of an atom is found in the nucleus.
If you mean the nucleus of an atom, different atom have different masses - an uranium atom has more than 200 times the mass of a hydrogen-1 atom (and most of that mass is in the nucleus).
The bulk of the mass of the atom is concenrated in the small, dense nucleus.
There is a dense, positively charged mass in the center of an atom...
There is a dense, positively charged mass in the center of an atom.
the denser part of an atom is the nucleus. about 99% of the mass of an atom is concentrated within the atom.
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.
Nucleus. Composed of Protons and neutrons. Can be sub-divided further but you probably don't have to know that. (quarks and muons and such.)
He described the mass of an atom was located in a single point not equally shared as the plumb pudding model suggested it. However he did not use the term nucleus in his report.
The Nucleus is the small, dense center of an atom where nearly all of the mass is contained. The nucleus is made up of positively charge protons (the number of which determines the element) and electrically neutral neutrons (with the exception of hydrogen-1, which has only a single proton).
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
Greek philosopher Democritus.
At the center of a black hole is a mass that has collapsed to an infinitely dense point.
the nucleus is the center of an atom that contains the positively charged protons and the neutrally charged neutrons. It contains most of the mass of the atom.
