How many elements of oxygen are there?
six chemical elements
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).
Is oxygen a rare element?
Oxygen is the third most abundant element in the universe, according to the Thomas Jefferson National Accelerator Facility. However, its reactivity made it relatively rare in early Earth’s atmosphere.
How abundant is the element oxygen?
After hydrogen and helium, oxygen is the third most abundant chemical element in the known universe. It is the second most abundant element in the Earth’s geosphere after iron and the most abundant element by mass in the Earth’s crust — at about 47% to 49%.
How much is the element oxygen worth?
Oxygen therefore contributes a majority of a human body’s mass, followed by Carbon. (Because of its low atomic weight, even though 63% of the atoms in a body are Hydrogren, this equates to just 10% of the mass of a body)….Value.

Is oxygen the most common element?
Oxygen is the third most abundant element in the universe after hydrogen and helium (by mass) and it’s the most abundant element (by mass) in the Earth’s crust, making up almost half of the crust’s mass.
What element is most like oxygen?
Elements that will have similar properties to oxygen will be the one present in its own group. These include sulphur, selenium and tellurium.
What is the element oxygen related to?
A very reactive element, oxygen (O) belongs to the non-metals family in the periodic table which consists of elements such as carbon (C). Oxygen is the most common element found in the Earth’s crust just ahead of silicon (Si) but also the main constituent of the oceans and of sand.
What is the element oxygen used for?
Living creatures use this chemical element for different purposes inside their bodies. Humans use oxygen to help them produce various things, heal diseases, ease daily activities and many other things. Furthermore, oxygen is also used for industrial purposes.
How is oxygen a dangerous element?
Beware the Dangers of Oxygen There’s a caustic substance common to our environment whose very presence turns iron into brittle rust , dramatically increases the risk of fire and explosion, and sometimes destroys the cells of the very organisms that depend on it for survival.
