Groups . Most periodic tables are color-coded so that you can see at a glance which elements share common properties with each other. Sometimes these clusters of elements (e.g., alkali metals, transition metals, non-metals) are called element groups, yet you'll also hear chemists refer to the columns (moving top to bottom) of the periodic table called element groups.

The periodic table we use today is based on the one devised and published by Dmitri Mendeleev in 1869. Mendeleev found he could arrange the 65 elements then known in a grid or table so that each element had: 1. A higher atomic weight than the one on its left. For example, magnesium (atomic weight 24.3) is placed to the right of sodium (atomic ...

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.
