A parent atom is a term used to describe the original state of an atom or element before it undergoes a chemical change. For instance, it may be used when discussing radioactive decay. The original element would be the parent atom, and the element that results from the radioactive decay would be the daughter atom. It may also be used when discussing ions. The parent atom would be the element before it undergoes ionization, and the daughter atom would be the resulting cation or anion.
Constant and Unique
The smallest atom is hydrogen.
hydrogen
polyvalent atom
The atom with the greater attraction for shared electrons in the molecule is the more electronegative atom.
A negative ion has gained one or more electrons to become negatively charged, while its parent atom is neutral with an equal number of protons and electrons. This means the negative ion has more electrons than its parent atom.
A negative ion would be considered larger than its parent atom. This is because electrons have mass, which makes the ions gain mass to outgrow their parent atoms.
A positive ion is smaller than its parent atom because it has less electrons than its parent atom. The reduced number of electrons are then pulled more tightly to the positive nucleus because the number of protons remains the same, and these now exceed the electrons in number.
A negative ion is typically larger than its parent atom. When an atom gains an electron to become a negative ion, the added electron increases the electron-electron repulsions, causing the electron cloud to expand. This expansion results in a larger ionic radius compared to the neutral atom.
Only the anion is greater than the atom because gained an electron.
The cast of Olaf-An Atom - 1913 includes: Harry Carey as Olaf, an Atom Donald Crisp as The Beggar Frank Evans as The Blacksmith Charles Hill Mailes as A Parent Thomas Jefferson as The Doctor Claire McDowell as A Parent
The anion has a negative electrical charge and is more chemically reactive than the atom.
Constant and Unique
In general, a cation is smaller than its parent atom because it has lost one or more electrons, leading to a decrease in electron-electron repulsion and a smaller electron cloud.
The parent structure of PH3 is trigonal pyramidal. It consists of a central phosphorus atom with three hydrogen atoms bonded to it, giving it a pyramidal shape.
It's called Radioactive Decay. It transforms the atom (or "parent nuclide") into a "daughter nuclide"http://en.wikipedia.org/wiki/Radioactive_decay
according to google XD, this is the radioactive atom that decays to product a daughter isotope
