The periodic table is an arrangment of the chemical elements ordered by atomic number so that chemical periodic properties of the elements (chemical periodicity) are made clear. There is no one single or best structure for the periodic table but by whatever consensus there is, the standard form used here is very useful and the most common.

Modern periodic table. The atomic number of each element increases than the element preceds it in the same period by whole one , Each period begins by filling a new energy level with one electron , then filling the atomic energy sublevels lying in the same period successively , until we reach the last element in the period which is a noble gas that has completely filled energy levels .
Using the periodic table, you can classify the elements in many ways. One useful way is by metals, nonmetals, and metalloids. The periodic table is organized in families and periods. Metals In the periodic table, you can see a stair-stepped line starting at Boron (B), atomic number 5, and going all the way down to […]

Hydrogen is a chemical element with atomic number 1 which means there are 1 protons and 1 electrons in the atomic structure.The chemical symbol for Hydrogen is H. With a standard atomic weight of circa 1.008, hydrogen is the lightest element on the periodic table. Its monatomic form (H) is the most abundant chemical substance in the Universe, constituting roughly 75% of all baryonic mass.

There are 118 elements in the periodic table, out of which 92 are natural elements and the remaining are synthetic elements. Technetium (atomic number 43) was the first synthetic element discovered, that filled the mysterious gap between the elements, Molybdenum (atomic weight 42) and Ruthenium (atomic weight 44) in the periodic table.
