There must be at least two atoms of chlorine in a chlorine molecule. This produces what is called a diatomic molecule. The gas hydrogen also appears as a diatomic molecule. More »

For a chlorine atom to become a chloride ion, it must gain an electron. The chloride ion has a negative charge and is written as Cl-. Chlorine gains an electron because it has seven valence electrons, and to be a full oc... More »

The difference between chlorine-35 and chlorine-37 is that chlorine-35 has 18 neurons, while chlorine-37 has 19 neurons. Chlorine is a chemical element with atomic number 17 and an atomic weight of 35.4527 grams per mole... More »

A molecule of oxygen contains two atoms. Oxygen never exists freely in nature but rather exists as a diatomic molecule, meaning two oxygen atoms bond together and share electrons. Other diatomic molecules include chlorin... More »

A molecule consists of at least two atoms of the same element, while a compound includes at least two elements. An example of a molecule would be molecular hydrogen, which has two atoms of hydrogen and is represented as ... More »

The Lewis structure for SeO2, known as selenium dioxide, is one atom of selenium doubly bonded to a molecule of oxygen on each side, resulting in a total of two atoms of oxygen. Selenium's electrons are a completed pair,... More »

A polyatomic element is a chemical element that naturally exists as a compound molecule containing more than two atoms of the same element joined together by covalent bonds. There are only three polyatomic elements found... More »
