What is the difference between the stability of atom and the stability of nucleus?
Wiki User
∙ 14y ago
an atom is the smallest part of a component composed of a nucleus and electrons gravitating around the nucleus. Under certain conditions, involving pressure, heat or any externally applied energy, electrons are eager (eagerness depending on the kind of component) to leave their orbiting path, which makes the atom unstable, meaning into an ion state also eager to combine with another atom to replace the missing one (common electron). As for the nucleus of the same atom (concentrating most of the mass of the component), it's far different: cohesion between neutrons and protons (and many others particles recently discovered) is very high and the necessary energy able to disrupt such cohesion is hugely high and unavailable in normal existing conditions. That's where we reach nuclear reactions science and also the big bang theory at the origin of a galaxy.

What is the principal effect of the presence of neutrons in the nucleus of an atom?
It is suposed that neutrons are necessary for the stability of the atomic nucleus.
What ratio can be used to predict the stability of an atom?
This is the protons/neutrons ratio in the atomic nucleus.
What is difference between potassium atom and molecule?
an atom is a nucleus,[ nutrons and protons] and a number of electrons whirring around it. a molecule is a combination of two or more atoms to make something new
How can you compare atom and cation?
An atom is a neutral structure consisting of a single nucleus with its orbiting electrons. A cation is a positively charged structure consisting of a single nucleus with its orbiting electrons. The major difference between an atom and a cation is that the cation has lost one or more electrons and therefore has a positive charge overall.
What is between the electrons and the nucleus of an Atom?
Nucleus is positively charged and contains positively charged protons and neutral neutrons. The nucleus is present at the centre of an atom. The electrons are negatively charged and revolve around the nucleus.
What does neutrons do in the atom?
neutrons are neutral species that are found inside the nucleus of an atom (along with the protons). they minimize the repulsion between the positively charged protons, thereby giving stability to the nucleus.
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 is the principal effect of the presence of neutrons in the nucleus of an atom?
It is suposed that neutrons are necessary for the stability of the atomic nucleus.
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 happens to an atom with a nucleus that falls outside the band of stability?
It would be radioactive and the nucleus would undergo nuclear decomposition.
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 cause the atom's nucleus to become unstable?
Inside the nucleus of an atom, there is a competition between two principle forces: strong nuclear forces which keep the nucleus together, and electrostatic forces between the protons which want to blow it apart. Different proton-neutron structures causes changes between these two forces which affects the stability of the atom. The exact instant an atom decays is a quantum perturbation. Every time the atom vibrates, it has a chance of overcoming the activation energy barrier for decay.
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 makes an element unstable or radioactive?
The stability of an atom depends on a balance between the numbers of protons and neutrons in its nucleus and also on the total size of its nucleus; atoms with sufficiently large nuclei are inherently unstable. Please see the link.
What ratio can be used to predict the stability of an atom?
This is the protons/neutrons ratio in the atomic nucleus.
