Oxygen gas is free from odor, taste and color, combines with the majority of other elements, supports combustion, is very paramagnetic and has a pale blue color in both its solid and liquid forms. Oxygen is also a part o... More »

Oxygen is a non-flammable gas that is colorless and odorless. It has a melting point of 54.36 Kelvin and a boiling point of 90.19 Kelvin. Oxygen speeds the rate of combustion by acting as an oxidizing agent. More »

Titanium belongs to the group of elements known as transition metals, known for their variable valence and oxidation states. That is, the electrons in these elements can inhabit various orbits around the nucleus, and the... More »

Properties of matter, defined by Education Portal, are divided into two groups: physical properties that include color, density, mass, boiling point, volume, solubility, malleability and temperature; and chemical propert... More »

Periodic law, also known as Mendeleev's law, is the concept that the chemical and physical properties of elements are based on an element's atomic weight when arranged by increasing periodic atomic number. Periodic law w... More »

The periodic table classifies chemical elements by their similarities and properties. Each square in the periodic table shows an element's atomic number, its symbol, its name and its atomic weight, which is the number of... More »

The “Law of Octaves” stated that when the elements are ordered by increasing atomic weights, every eighth group of the elements has similar chemical properties. This pattern is similar to piano octaves, which are also gr... More »
