What Are The Trends In The Periodic Table

Electronegativity ionization energy electron affinity atomic radius melting point and metallic character.

Trend across period 1 compare the first ionisation energies of h and he. Periodic trends from the changes in the atomic structure of the chemical elements within their respective periods and groups in the periodic table. In a group the atomic size increases due to the addition of shells as we move from one period to another. Periodic trends arising from the arrangement of the periodic table provide chemists with an invaluable tool to quickly predict an element s properties.

When elements are arranged as in the periodic table some trends can be determined. The trends in first ionisation energies amongst elements in the periodic table can be explained on the basis of variations in one of the four above factors. Neither have inner shells so there is no shielding. The periodic table arranges elements in increasing atomic number the columns and rows are formed based on the electron configuration of the element.

As you move down a group in the. Major periodic trends include electronegativity ionization energy electron affinity atomic radii ionic radius metallic character and chemical reactivity. These laws enable the chemical elements to be. The distance between the centre of the nucleus and the outermost shell of an atom is known as the atomic radius.
