Oxygen comes from trees
you need oxygen to breath
the symbol for Oxygen is O, the Oxygen ion is 2-. therefore the symbol for the oxygen ion is O2-
Magnesium = Mg+2 Oxygen = O-2 (Mg+2)+(O-2) = MgO = Magnesium Oxide so the formula for oxygen + magnesium - oxygen + magnesium oxide
There are 2 oxygen atoms in dioxide
In 4 hydrogen atoms and 2 oxygen atoms, there are a total of 10 atoms (4 hydrogen + 2 oxygen).
Oxygen has 2 electrons in its first energy level.
it is what we breathe.
you can breathe
Ozone is a triatomic gas. It is an allotrope of oxygen.
They take in Cabon Dioxcde and give us Oxygen
. The brain makes up of 2% of total body weightThe brain doesn't feel pain. The brain has huge oxygen needs about 20% of supplied oxygen. 80% of the brain is water, always need to be hydratedproperly
the symbol for Oxygen is O, the Oxygen ion is 2-. therefore the symbol for the oxygen ion is O2-
The oxidation number of oxygen is -2 in most of its compounds
2 oxygen
Oxygen is a colorless odorless gaseous element. It is colorless as a gas, yet pale blue in color when a liquid. It is found in water, in most rocks and minerals, and in numerous organic compounds. Oxygen is capable of combining with all elements except the inert gases. Both solid and liquid oxygen contain unpaired electrons. Oxygen is in 21% of the atmosphere. Oxygen in the air is the ordinary form which contains 2 atoms per molecule, but oxygen in the atmosphere has 3 atoms per molecule.
Oxygen is a nonmetal. Oxygen 2 is a molecule composed of two oxygen atoms, and like all oxygen atoms, it is classified as a nonmetal on the periodic table.
1. Oxygen's Atomic Symbol is O2. Oxygen is colorless, tasteless & odorless3. Most of your body is made up of oxygen.4. You need Oxygen to live.5. Most animals & plants need oxygen for respiration6. Oxygen is a nonmetal7. Oxygen (O) is used in many medicines8. YOU CAN'T LIVE WITHOUT IT!!!! =)
It burns slowly in oxygen causing a glow that will not harm you. It also can be used as a fertillizer.
