Unfortunately, it is radioactive, and increased exposure to it has been correlated with an increased lung cancer risk.īecause radon comes from the ground, we cannot avoid it entirely. Because it is a noble gas, radon is not chemically reactive. The atomic number of each element increases by one, reading from left to right.

EXCLUSIVE TABLES COMING WITH A UNIQUE SERIAL NUMBER. With a standard atomic weight of circa 1.008, hydrogen is the lightest element on the periodic table. Visualize trends, 3D orbitals, isotopes, and mix compounds. Members of a group typically have similar properties and electron configurations in their outer shell. 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. Interactive periodic table showing names, electrons, and oxidation states. Radon is an invisible, odorless noble gas that is slowly released from the ground, particularly from rocks and soils whose uranium content is high. Group A vertical column in the periodic table.
