What is the difference between the stability of atom and the stability of nucleus?
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 else can I help you with?
Why does electron surround nucleus?
Electrons surround the nucleus of an atom due to the attraction between the positive charge of the protons in the nucleus and the negative charge of the electrons. This electrostatic force of attraction keeps the electrons in orbit around the nucleus, maintaining the stability of the 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.
How many protons nucleus have?
It depends on what atom it is, the number of protons in the nucleus of an atom or ion defines what type of atom it is.
How is the structure of the nucleus of a polonium 218 atom different from the structure of the nucleus of a radon 222 atom?
The nucleus of a polonium-218 atom contains 84 protons and 134 neutrons, while the nucleus of a radon-222 atom contains 86 protons and 136 neutrons. This difference in the number of protons and neutrons results in different nuclear properties and stability for each atom.
Related to the potential energy stored in bonds between particles in the nucleus of an atom?
The potential energy stored in the bonds between particles in the nucleus of an atom is primarily due to the strong nuclear force, which binds protons and neutrons together. This energy is released during nuclear reactions, such as fission and fusion, where the nucleus is either split or combined, respectively. The stability of the nucleus is influenced by the balance between the attractive strong force and the repulsive electromagnetic force between protons. This nuclear binding energy is a crucial factor in understanding atomic stability and energy production in stars and nuclear reactors.
How does the electron cloud's distance from the nucleus affect the atom's overall stability?
The distance of the electron cloud from the nucleus affects the atom's stability. When the electron cloud is closer to the nucleus, the atom is more stable. This is because the positively charged nucleus and negatively charged electrons are closer together, creating a stronger attraction. Conversely, if the electron cloud is further from the nucleus, the atom is less stable as the attraction between the nucleus and electrons is weaker.
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 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 a particle in the nucleus of an atom that does not have a charge?
A neutron is a particle in the nucleus of an atom that does not have a charge. It helps to stabilize the nucleus by balancing the repulsive forces between positively charged protons. Neutrons play a crucial role in determining the stability and characteristics of an atom.
Why does electron surround nucleus?
Electrons surround the nucleus of an atom due to the attraction between the positive charge of the protons in the nucleus and the negative charge of the electrons. This electrostatic force of attraction keeps the electrons in orbit around the nucleus, maintaining the stability of the atom.
How do hydrogen neutrons contribute to the stability and properties of an atom?
Hydrogen neutrons contribute to the stability and properties of an atom by helping to balance the positive charge of the protons in the nucleus. Neutrons also play a role in determining the mass of the atom and can affect its stability by influencing the nuclear forces within the 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 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 is the mass defect formula used to calculate the difference in mass between the nucleus of an atom and the sum of its individual nucleons?
The mass defect formula is used to calculate the difference in mass between the nucleus of an atom and the sum of its individual nucleons. It is calculated by subtracting the actual mass of the nucleus from the sum of the masses of its individual protons and neutrons.
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 changes would occur if the number of neutrons in an atom's nucleus were altered?
If the number of neutrons in an atom's nucleus were altered, it could lead to changes in the stability of the atom, potentially causing it to become radioactive or undergo nuclear reactions. This could affect the atom's properties, such as its mass, stability, and reactivity.
