On this page you can discover the chemical properties of oxygen and information about oxygen and other elements on the periodic table such as sulfur, nitrogen, fluorine or helium. You will also learn what oxygen is for and you will know what its uses are through its properties associated with oxygen such as its atomic number or the usual state in which oxygen can be found.
You will see qualities of oxygen such as its melting and boiling point, its magnetic properties or what its chemical symbol is. In addition, here you will find information about its atomic properties such as the distribution of electrons in oxygen atoms and other properties.
For some elements, some of this information is unknown. In these cases we show the properties attributed to them.
One of the properties of non-metal elements such as oxygen is for example that non-metal elements are poor conductors of heat and electricity. Oxygen, like the other non-metal elements, has no luster. Due to their brittleness, nonmetals such as oxygen cannot be flattened to form sheets or stretched to become threads.
The state of oxygen in its natural form is gaseous (paramagnetic). Oxygen is a colorless looking chemical element and belongs to the group of nonmetals. The atomic number of oxygen is 8. The chemical symbol for oxygen is O. The melting point of oxygen is 50.35 degrees Kelvin or -221.8 degrees Celsius or degrees Celsius. The boiling point of oxygen is 90.18 degrees Kelvin or -181.97 degrees Celsius or degrees Celsius.
Oxygen is an important chemical element that it is. Colorless, odorless and tasteless. If you’ve ever wondered what oxygen is for , here is a list of its possible uses:
The atomic mass of an element is determined by the total mass of neutrons and protons that can be found in a single atom belonging to this element. As for the position where to find oxygen within the periodic table of the elements, oxygen is in group 16 and period 2. Oxygen has an atomic mass of 15,9994 u.
The electronic configuration for oxygen is 1s22s22p4. The electronic configuration of the elements, determines the form in which the electrons are structured in the atoms of an element. The atomic radius or Bohr radius of oxygen is 60 (48) pm (Bohr radius) pm, its covalent radius is 73 pm, and its Van der Waals radius is 152 pm.
