three isotopes of oxygen

Isotopes are atoms of the same element having different atomic mass but same atomic number. For e.g., there are three isotopes of hydrogen with atomic mass 1, 2, and 3. According to Mendeleev's periodic table these should be placed at three separate places. ..

Atoms of the same element having the same atomic number but different mass numbers are called isotopes. The nuclei of these atoms have same number of protons but different number of neutrons. All the properties of the isotopes depending upon mass are different. Differen..

Oxygen - Oxygen is very essential for the existence of human life on Earth. It is the most abundant element on the surface of the Earth. In a free state, it is present in the Earth's atmosphere to an extent of about 21% by volume, (23.15% by mass) In the combined form, it consti..

Isotopes are the different forms of the same element, which have the same atomic number but different mass numbers. The isotopes of hydrogen are protium, deuterium and tritium with mass number 1, 2 and 3 respectively. The relative abundance of three iso..

1. Oxygen is a colorless, odorless and tasteless gas. 2. It is neutral to litmus. 3. It rekindles a glowing splinter. 4. When mixed with colorless nitric oxide, it forms reddish brown fumes of nitrogen dioxide. 5. It is absorbed by alkaline pyrogallol solution that tur..

Iron does not combine with oxygen in ordinary temperature. When it is strongly heated in air, it forms a black compound called iron (II,III) oxide. Iron rusts in damp air forming a brown mixture of iron (III) oxide Fe 2 O 3 and iron (III) hydroxide Fe(OH)..

Oxygen Cycle - Oxygen is another essential element for living organisms. It is present in large quantities (20.95% v/v) in the atmosphere and is also seen in bound state in water and as oxides and carbonates in rocks. Dissolved oxygen in water is the source of oxy..
