Plants generate oxygen in the chemical reaction known as photosynthesis. Oxygen is in the second row and sixteenth column on the periodic table.Answer and Explanation: The average atomic mass of oxygen is 15.999 AMU. This value rounds to 16, which indicates that oxygen-16 is the most abundant ...
mass- the property of a body that causes it to have weight in a gravitational field combining weight,eq,equivalent weight,equivalent- the atomic weight of an element that has the same combining capacity as a given weight of another element; the standard is 8 for oxygen ...

The modern masses for calcium, magnesium, and oxygen are still nearly in the 5:3:2 ratios of the original masses. Notice especially that the atomic mass of hydrogen is not precisely equal to 1, because the atomic mass scale is now based on the most common variety of carbon being exactly...
Oxygen is the third most abundant element in the universe by mass, after hydrogen and helium, and the most abundant element by mass in the Earth’s crust. Dioxygen as a gas makes up 20.9% of the volume of Earth’s atmosphere and is also present in the form of water vapor and CO2. ...
The inadequacy of oxygen as an arbitary standard led to the selection of the carbon-12 isotope of carbon as the arbitary standard. The relative atomic mass of an element is defined as the weight in grams of the number of atoms of the element contained in 12.00 g of carbon-12. ...

Oxygen is also the name of the molecular compound O 2 , also known as dioxygen , formed from two covalently linked oxygen atoms with a spin triplet electron configuration. Overview Oxygen is the third most abundant element in the universe by mass, after hydrogen and helium, and the most ...
