Without hybridization, oxygen has a valence electron configuration of 2s22p4. Which means it has 2 unpaired electrons; therefore it can form 2 bonds.
Oxygen can form up to three bonds with other elements.

Chemical bonds. For example, with ionic bonds it is the attraction of opposite charges. With covalent bonds it is the sharing of electrons.
Chemical reactions break down the bonds holding the rocks together, causing them to fall apart, forming smaller and smaller pieces. Chemical weathering is much more common in locations where there is a lot of water. This is because water is important to many of the chemical reactions that can take place. Warmer temperatures are also more friendly to chemical weathering. The most common types of chemical weathering are oxidation, hydrolysis and carbonation.
Plants can make us live as they give out oxygen.
He came up with the conservation of mass, discovered oxygen and its role in combustion, and came up with the basis of the modern chemical nomenclature. He did many other things, which can be googled.
If you mean changing one element into another, like uranium 238 into plutonium 239, which happens in nuclear reactors, the word is 'transmutation'. Otherwise many chemical reactions form new substances, without the elements involved changing, and these would be called 'chemical reactions'.
Carbon makes four bonds with oxygen in carbon dioxide.
Calcium can make two bonds because it is in the same group as oxygen.
Two bonds in total. The oxygen atom forms two covalent bonds, one to each of two hydrogen atoms. This can be represented as H - O - H.
it has two bonds because the oxygen can make a bond with each hydrogen
2 covalent bonds: H-O-H. In other words, it makes water.

A chemical bond is composed of many atoms.

Chemical bonds are: ionic, covalent, intermetallic.
Si will have two bonds to the two Hydrogens, and a double bond to the Oxygen. The Oxygen will have two pairs of unpaired valence electrons.
3 bonds are commonly formed by nitrogen and 2 are commonly formed by oxygen.
