sulphur joins oxygen two atoms to form sulphur dioxide
The atoms of oxygen join to form the diatomic molecule O2 with a covalent bond.
There's a picture in the linked page showing a single water molecule, consisting of one oxygen atom (in red) and two hydrogen atoms (in white), hence, the formula for a single molecule of water, H2O.
Two hydrogen atoms need to be combined with one oxygen atom to form a molecule of water (H2O). Or you could have two hydrogen to two oxygen atoms, forming hydrogen peroxide (H2O2) but this is unstable and decomposes back to water and oxygen gas.
An oxygen atom joins with another oxygen atom in a covalent bond. This means that they share two of each other's outer electrons, which in turn means that they are both stable as they now have full outer shells - they join together and become O2.
when two non metalic atoms join together eg o2 is two oxygen atoms
Two atoms of hydrogen and one atom of oxygen.
Hydrogen atoms released from water are added to carbon dioxide molecules so that carbon oxygen bonds are broken and carbon atoms can join together. Carbon dioxide consists of a carbon atom attached to two oxygen atoms. That way, a carbon atom joins two other carbon atoms. One of the hydrogen atoms joins the carbon atom and one of the hydrogen atoms joins with the oxygen atom. You end up with the carbon atom attached to four different atoms.
Two hydrogen atoms. As H2, they join one oxygen atom to form H2O

Oxygen always has atomic number 8, but that has nothing directly to do with the rest of the question. The number of hydrogen atoms needed is 2, because that is what must be shared to fill the "outer shell" of both the oxygen atom and each hydrogen atom.
What elemets are in CO2? The two main elements of CO2 are: 1. Oxygen 2. Carbon
Two hydrogen atoms need to be combined with one oxygen atom to form a molecule of water (H2O). Or you could have two hydrogen to two oxygen atoms, forming hydrogen peroxide (H2O2) but this is unstable and decomposes back to water and oxygen gas.
Carbon atoms join with oxygen to make a gas called carbon trioxide.
it forms a triple bond
No. When making water by burning Hydrogen in Oxygen (a very explosive reaction) is that 2 atoms of Hydrogen and 1 atom of Oxygen join together to form 1 water molecular - H2O.
An oxygen atom joins with another oxygen atom in a covalent bond. This means that they share two of each other's outer electrons, which in turn means that they are both stable as they now have full outer shells - they join together and become O2.
