Want this question answered?
In order for an atom to be chemically stable it must have 8 valence electrons.
Its position predicts several useful characteristics: 1. The no. of valence electrons/the type of valence orbitals 2. The nature of element 3. Other Elements having similar chemistry 4. rough idea of the ionization enthalpy, electronegativity, and other parameters and many more things
They are all composed of the same elementary particles, i.e. all of them have protons and electrons (and all but one have neutrons). Also: - all of them have mass - all of them exist in space and time - all of them interact with other elements by means of electromagnetic forces and gravitational forces - all of them exist in more than one isotopic variety.
9 protons and 10 neutrons in F-19 isotope.
The electrons form the bond. A chemical bond is formed when an electron is shared with another atom, so both atoms may have 8 electrons but only 15 exist in the pair. You should Google covalent, ionic, and metallic bonding for more details. Try image search on these terms for a better idea.
For main group elements the column number is a concrete indication of then number of valence electrons (and therefore oxidation number). And since it tells you the number of valence electrons you can get a substantially reliable idea of how reactive the element is
The outer or valence electrons are the ones involved in bonding.Valence electrons
No, valence electrons are the electrons in the outermost energy level of an atom. A molecule is the smallest physical unit of an element or compound, consisting of one or more like atoms in an element and two or more different atoms in a compound.
These particles are the electrons.

VESPR theory :)
Valence shell electron pair repulsion theory, otherwise known as VSEPR theory, is used to predict the geometry of molecules. This is based on the number of electron pairs surrounding their central atoms. This is based on the idea that valence electron pairs surrounding and Adam generally repel each other, so their arrangement is based on the minimizing of said repulsion.

Valency of carbon is 4.Valency of chlorine is 1
absofreakenlotely! :) good idea
