An element is a species of atoms having the same number of protons in their atomic
nuclei.

Periodic Table
An arrangement of the elements in order of their atomic numbers such that elements with similar properties fall in the same
column, or group.

Groups
A vertical column of elements in the periodic table; elements in a group share
chemical properties.

Chemistry is a branch of physical science that studies the composition, structure,
properties and change of matter.

Non-Metals
An Element that conducts heat and electricity poorly.

Dmitri Mendeleev
Russian chemist, that formulated the periodic law, created a farsighted version of the periodic table of elements, and used it to correct the
properties of some already discovered elements and also to predict the properties of eight elements yet to be discovered.
