Terminology used in Chemistry.

Ionization energy: decreases when going down the group because when going down the group the number of shells around the atomic radius increases and the outer electrons become weakly attracted by the nucleus. As you go to the rite the no. Of neutrons in the nucleus (+) charged particles increases. This pulls the electrons towards the nucleus. Therefore making it more difficult to remove the electrons. Electro-positively: increases down the group e.g. Potassium is more …

…a regular arrangement of particles in a crystalline solid. Metallic bonding: is the electrostatic force attraction between neighboring metallic ions, it is formed as of the formation of a sea of decolized electrons. Ionic (electrovalent): is the electrostatic force of attration between metallic ions and non-metallic ions. Ductility and metabolite: metals are double and methable because they have a loosely packed layers which can slide over each other without breaking more bonds that are made.
