Periodic table is a method of classifying elements
elements are arranged in order of increasing atomic number
Metals are to the left, while non metals are to the right.
Reactivity of metals increases down the periodic table
Reactivity of non-metals decrease down the period
Ionization energies increases from left to right and from bottom to top of the periodic table.
This is because of their ease to lose electrons and become a cation
It is the ease by which an atom can accept an electron. The higher the electron affinity, the more the attraction.
The elements in the upper right side have a high electronegativity, and the elements on the lower left side have low electronegativity
non-metals are found upper right side.
it states that when the elements are arranged according to their atomic number, elements with similar properties appear at regualr intervals
