An atom is the complete building block of all elements, each element has its own unique atomic formation. An atom consists of a nucleus with a cloud of electrons surrounding it, and is electrically neutral unless ionised. The nucleus at the center of the atom consists of protons which are positively charged, and neutrons which are uncharged, and these are all bound together by the 'strong nuclear force', which has a very short range so it only is effective within the nucleus. Each chemical element (see the Periodic Table) is defined by a unique number of protons called the Atomic Number, and can have a variable number of neutrons so that there are different isotopes of the same element. The number of electrons in the atom is equal to the number of protons in the nucleus, unless the atom has been ionised.

What statement best describes the density of an atom's nucleus?
The density of the nucleus is 1000's times the density of the entire atom.
How many particles are in the nucleus of an atom of xenon?
There can be between 124 and 136 particles (neutrons and protons) in the nucleus of a xenon atom.
What is the difference between nuclear force and binding energy?
The nuclear force is what binds the nucleons, which are protons and neutrons, together in the nucleus of an atom. The binding energy is the amount of energy needed to break the atom apart. The one is a force, and the other is a measurement.
What is the center of the atom?
The center of an atom is a nucleus. In the center of the nucleus, there is protons and neutrons. Around the atom, is the shell. Using the shell, as an orbit is the electron.
What are two differences between the nucleus of an atom and the electrons of an atom?
The nucleus of an atom has a positive electrical charge, the electrons have a negative electrical charge, and the nucleus is thousands of times heavier than the electrons (the exact ratio of weight varies, because although there are always as many protons as electrons, in a neutral atom, the number of neutrons varies).
What is the difference between a proton an electron and a neutron and where can they be found?
a proton is a positively charged particle that is found in the nucleus of an atom, a neutron is a particle that has no charge and is also found in the nucleus of an atom, an electron is a negatively charged atom that is constantly circling the nucleus of an atom.
What are the major difference between the plum pudding and planetary models of the atom?
The plum pudding model of an atom has not a nucleus; in 1904 the nucleus, protons, neutrons were not discovered. See the link below.
What is the difference between photon and neutron?
Neutron is a neutral particle present within the nucleus of an atom. Proton is a positively charged particle present within the nucleus of an atom. Photons are particles of light.
What statement best describes the density of an atom's nucleus?
The density of the nucleus is 1000's times the density of the entire atom.
What is the difference between an animal nucleus and an atom's nucleus?
Atomic nucleus is a notion of atomic physics and contain protons and neutrons.The nucleus of a biological cell has an extremely different structure, role and composition.
What is the mass defect?
If you add the exact mass of the protons, neutrons, and electrons in an atom you do not get the exact atomic mass of the isotope. The diference is called the mass defect. The difference between the mass of the atomic nucleus and the sum of the masses of the particles within the nucleus is known as the mass defect.
What is the difference between nucleus and nucleus?
There is no difference. Both represent the same.
What is the difference between the nucleus and nucleus?
There is no difference. Both represent the same.
What is the difference between neutron and a electorns?
The difference between neutron are neutral, and electrons have a negative change too them. Neutron is a neutral particle that exists in the nucleus of an atom. The year when the neutron was founded was 1932.
How many particles are in the nucleus of an atom of xenon?
There can be between 124 and 136 particles (neutrons and protons) in the nucleus of a xenon atom.
What is the difference between a neutron a proton and a electron?
A nuetron has no charge and resides in the nucleus of an atom along with protons that have a positive charge. Electrons have a negative charge and are in the electron shells around the nucleus.
What is the difference between an atom a molecule and an element?
An atom is a nucleus of protons and neutrons with electrons orbiting around. An element is an atom with a specific amount of protons, neutrons, and electrons. A molecule is a bunch of atoms stuck together.
