Periodicity.

One might ask what is hebdomadaryity? The word periodicity has many an(prenominal) a(prenominal) meanings. Periodicity is defined as the occurrence of similar properties in elements having similar positions in the periodic dining table. Periodicity is found through with(p) certain periodic impetuss. There atomic number 18 four periodic trends found in the periodic table: atomic radius, ionization might, electron affinity, and electronegativity. The first periodic trend is atomic radius. nuclear radius is found in some(prenominal) ways. The radii of some atoms argon determined by measuring the outdo between give cargon atoms that are joined together. There are other measurements that are taken from bond lengths of compound atoms. As you playact nap a host, a new electron shell is added to the atoms. This makes the atomic radius of an atom increase. Thus, when you terminate passel a pigeonholing the atomic radius increases. As you relocation from left(a) to righ t, the radii reducings. You are adding more protons and electrons, but the electrons are in the alike(p) efficacy level so the protons are attracting the electron wave. This takes up less(prenominal) room, and it makes the atom radius smaller. ionisation Energy is the amount of energy required to remove an electron from an atom in its ground state. Ionization energy strikes as you move down a group of elements, but it increases across a period.

The farther you move down in a group, the farther away from the magnetic core the start energy level is. More electrons lie between the outer(prenominal) electrons and the nucleus. These outer electrons are shie! lded, and they dont have as a great deal hold to the atom so they can be long-winded removed. This requires less ionization energy, thus, making the ionization energy decrease as you move down the periodic table. As you move left to right, the atoms have more pull on their electrons. It...
