When an atom is stable what is happening with the attractive and repulsive forces in the nucleus?
Inside an atom's nucleus there is a neutron, which has no charge, therefore no attractive or repulsive forces. The proton carries a positive charge, though, and repels the negative charge of the electron particle which exists somewhere outside of the nucleus.I'm yet of the old technology which thinks that protons and electron attract. Of course, that doesn't explain why the electron don't crash into the proton, but that's another story.
How does binding energy per nucleon effect the stability of a nucleus?
The greater the nuclear binding energy, the more stable the nucleus. Even numbers of nucleons also make the nucleus more stable.
Some atoms such as carbon-14 whose nuclei are not stable lose parts of their nucleus through decay -In the process they become another element -Atoms such as this are said to be?
Radioactive.
What are protons and where are they found?
Protons are a type of subatomic particle, which are found in the nucleus of every atom. Protons have an electrical charge of +1. A proton is about 2000 times heavier than an electron.
When is an object in stable equilibrium?
Atoms are generally stable if they meet a few conditions:Their valence electron shell is filled. This can occur by ionizing (gaining or losing electrons so that the highest-energy shell is full), or by electron sharing (via an electron 'sea' in metals, or by sharing of pairs of electrons in non-metals). Atoms with partially-full valence shells are chemically unstable, meaning that they react very readily with other elements. A nucleus with Too few neutrons will tend to capture its electrons or emit positrons (anti-electrons), neutralizing a proton and turning into a different element.A nucleus with Too many neutrons will tend to emit an electron by beta decay, turning one of its neutrons into a proton and turning into a different element.Additionally, once atoms reach a certain mass, there is no stable ratio of neutrons to protons, and the nucleus will either eject alpha particles from the nucleus until stable (alpha decay), or it will fission, breaking apart into two or more smaller nuclei.They have a certain ratio of protons and neutrons:Atoms with unstable proton to neutron ratios are radioactive, meaning they will undergo some type of decay until they reach a form that is stable.
Why does the separation of an electron from the neutral atom require more enery than the separation of an electron from the anion?
An explanation is via the electron cloud. In a neutral atom, equal number of electrons and protons means a stable separation of electrons from the nucleus and each electron is repulsed by the adjacent electrons at a stable distance. When one electron is removed forming an anion, the electron cloud will move closer to the nucleus because of lower electron repulsion (fewer competitors), and each electron is held more strongly by the protons. Since the force of attraction of proton-electron is stronger than before, removing the second electron will require even more energy than removing the first electron. ==========================
How is a stable nucleus different to an unstable nucleus?
A stable nucleus is one which will not decay, whereas an unstable nucleus will decay at some point, which cannot be predicted as decay is a random process, by alpha or beta decay.
What is the process that allows the nucleus of Radium to become stable?
Nuclear decay.
Why is a hydrogen nucleus charge?
A hydrogen nucleus has got just one electron, thereby meaning that it can either accept one more electron or give away its sole electron to attain the stable electronic configuration. However, it usually shows the non metallic behaviour of accepting an electron.
What is the process that allows the nucleus of radium-226 to become more stable?
Nuclear decay.
Why is electron gain enthalpy of inert gases positive?
Inert gases are the most stable ones, so if we try to add another electron, the stable electronic configuration is disturbed. So, we have supply energy for this process. Hence, electron gain enthalpy is positive.
Does the amount of energy stored in an electron increase or decrease as it moves toward the nucleus?
i am 99% sure that it decreases. that's because as closer they are, the more stable their orbitals are, so stable means less energy
What make a nucleus a stable?
A nucleus is stable if the electrostatic and strong nuclear forces balance out.
How does hydrogen show a reaction?
If you take Hydrogen in terms of energy levels it has 1 electron orbiting its nucleus. It only needs 1 more electron in its outer shell to become "stable" Therfore it is reactive and will react with other atoms to gain 1 electron.
Would rubidium be reactive and lose one electron to form an ionic bond?
yes because rubidium has only 1 electron on the outer shell so is not stable and because is far away from the nucleus the attraction is weaker therefore is more likely to react faster with another atom and get stable
What group of elements have stable electron confoguration?
The group of elements that have a stable electron configuration are the noble gases.
Is the electron cloud outside the nucleus?
Yes, though interestingly the probability density for finding an s orbital electron is actually higher in the nucleus than anywhere else (this assumes the nucleus and electron are point masses; in reality, they aren't, so it doesn't quite work out that way in the real world).
