The atomic radius of chlorine is approximately 79 picometers. One picometer is equal to a trillionth of a meter, commonly written as 10-12 meters. For example, 79 picometers is equal to 79*10-12 meters.
The atomic radius of an atom is the averaged distance from the center of an atom to the outer boundary of the orbitals that electrons occupy. Atoms are not perfect circles, which is why the actual radius may be larger or smaller at any single point. While most of the mass is concentrated in the nucleus of the atom, most of the volume is occupied by the electron clouds. Because of this, the atomic radius is many times larger than the radius of the nucleus.Learn More
Halogens include the elements chlorine, bromine and iodine, which form Group 7 in the periodic table of elements. Halogens vary in size, weight and other physical characteristics, but share several commonalities. All halogens are diatomic, which means they appear as molecules and have pairs of atoms.Full Answer >
There are three primary components inside an atom: neutrons, electrons and protons. The neutrons have no charge, while the protons have a positive charge and electrons have a negative charge. The neutrons and protons exist in a dense center area called the nuclei, while the electrons exist in another space, called orbitals, around the nuclei.Full Answer >
Covalent bonding describes the process where two atoms form a bond by sharing one or more electrons in order to fill up their outer orbital and become more stable. Covalent bonding typically occurs between two non-metals, which are mostly located on the right side of the periodic table.Full Answer >
Chemical properties of radium are its high reactivity and that it continuously breaks down and changes into other elements. Most radium isotopes, or atoms that have a different number of neutrons than the normal radium atom, are unstable and radioactive.Full Answer >
