What elements are in the oxygen group?
oxygen group element, also called chalcogen, any of the six chemical elements making up Group 16 (VIa) of the periodic classification—namely, oxygen (O), sulfur (S), selenium (Se), tellurium (Te), polonium (Po), and livermorium (Lv).
What is oxygen made out of?
Oxygen is a non-metal element and is found naturally as a molecule. Each molecule is made up of two oxygen atoms that are strongly joined together. Oxygen has low melting and boiling points, so it is in a gas state at room temperature.
What is the origin name of oxygen?
oxy genes

What are 2 physical properties of oxygen?
Oxygen is a colorless, odorless, tasteless gas. It changes from a gas to a liquid at a temperature of -182.96°C (-297.33°F). The liquid formed has a slightly bluish color to it. Liquid oxygen can then be solidified or frozen at a temperature of -218.4°C (-361.2°F).
What is the dot structure of oxygen?
Each O is surrounded by four dots and two sticks or lines, representing another 4 electrons in the O2 double bond. So each O is surrounded by 8 total valence electrons, giving it an octet and making it stable. The two letter O’s in the O2 Lewis structure represent the nuclei (centers) of the oxygen atoms.
Which elements are in the same group as oxygen?
Oxygen is in group 16/VIA, which is called the chalcogens, and members of the same group have similar properties. Sulfur and selenium are the next two elements in the group, and they react with hydrogen gas #(“H”_2”)# in a manner similar to oxygen.
What other elements is oxygen related to?
Oxygen group element, also called chalcogen, any of the six chemical elements making up Group 16 (VIa) of the periodic classification-namely, oxygen (O), sulfur (S), selenium (Se), tellurium (Te), polonium (Po), and livermorium (Lv). A relationship between the first three members of the group was recognized as early as 1829; tellurium was assigned its place by 1865, and polonium was discovered in 1898.
What is element best combines with oxygen?
When they breathe in air, the oxygen in the air combines with the elements carbon and hydrogen in the body. This releases energy that the animals use to survive. The animals then breathe out a compound of carbon and oxygen called carbon dioxide. Plants take in that carbon dioxide as part of a process called photosynthesis.
What are 5 uses for oxygen?
Common uses of oxygen include production of steel, plastics and textiles, brazing, welding and cutting of steels and other metals, rocket propellant, oxygen therapy, and life support systems in aircraft, submarines, spaceflight and diving.
