Valence Electrons
Valance electrons.
Electrons in metallic bonds are called "delocalized electrons", which means they exist in an atoms orbitals, but are extended over multiple atoms. It is often called a "sea of electrons" because the electrons are free to "roam" between atoms, and is what gives metal the ability to conduct electricity.See related links below for more information.
Valency electrons are free electrons that are not attracted to other atoms. Valency electrons most often occur in a vacuum where they are not attracted to atoms (the reason thermionic devices are vacuumed) so yes, electron clouds can occur, very rarely in our atmosphere in the form of corona discharge from high voltage devices and more commonly in the vacuum of space as a glob of ionic turbulence
The correct answer is: Atoms are often more stable when bonded to other atoms
The electrons specifically the outermost electrons determines the chemical properties. These are often called the valence electrons. The radioactivity of a particular isotope is determined by the nuclear composition in terms of protons and neutrons.
reactive. a radical, In chemistry, radicals (often referred to as free radicals) are atoms, molecules, or ions with unpaired electrons on an otherwise open shell configuration.
The kind of atom that likes to be oxidized.
elements having 3 electrons in its outermost orbit is known as trivalent atom
Atoms like to have a nice even number of Valence electrons or electrons on their outer shell ( i.e. two on the innermost ring and 8 on the second ring/shell) so when they do not they either lose or gain elements and bond with the other atom in the process.
At times the electrons involved in bonding are shared equally between the nuclei of two atoms and the bond is called a pure covalent bond. More often, however, the sharing is unequal and the electrons spend more time around the nucleus
The area in which electrons are arranged in energy levels is called "Main Energy Levels." The chart also includes configurations of the electrons. I have attached a link to explain.
Atoms often form ions by losing or gaining enough electrons to end up with a full outer shell. How many electrons are in a full outer shell for most atoms? Don't know? How about Googling full outer shell?
