Molecules BIG and SMALL
Electro shell
-Every period has an extra layer of electrons (shell)
aded around the nucleus.
-Keeps cuter electron shielded by the inner electrons.
Electronegativity
-Measure of atraction of nucleus to pair of electrons for a covalent band.
-Increases from moving left tu right on periodic table(noble gases).
-Per portun tu nucleus atraction increases in size
-Most electronegative flurine.
Intramolecular
Describe the forces of attraction. betewn atoms, molecules, and ions when they are placed close to each other. This is different from intramolecular forces which is another word for the covalent bonds inside molecules.
Ionic bonds
Ionic bond, also called electrovalent bond, type of linkage formed from the electrostatic attraction between oppositely charged ions in a chemical compound.
Intermolecular
Involve various competing interactions between electrons
and nuclei of different molecules. These interactions determine whether the generally smaller molecules of covalent molecular substances are solids, liquids, or gases at room temperature. this forces determinate properties like slipperiness, stickiness and viscosity.
Dispersion Forces
are interactions between charged
subatomic particles of any two neighbouring atoms.Dispersion forces can also be 'induced' by the
closeness o other local charged particles, for example ions.

Allotrope
When an element exists in more than one crystalline form, those forms are called allotropes; the two most common allotropes of carbon are diamond and graphite. Every carbon atom is covalently bonded at the four corners of the tetrahedron to four other carbon atoms.

Dipole-dipole forces
Dipole-dipole forces are attractive forces between the positive end of one polar molecule and the negative end of another polar molecule
