Oxygen is in Group 6 in the periodic table .
2-
The formula without the coefficient has 2 oxygens, but multiply that by the coefficient of 6 gets you 12 oxygens. In chemistry, a coefficient in front of a compound applies to everything in that compound even though there aren't any parentheses.
Oxygen itself has a charge of -2 as it is in group 6 of the table. It is not always -2 just to be careful, if there are more oxygens in the oxide, the result will be additive
a gas
non-metal
Oxygen is in p block. it is a useful gas. oxygens atomic number is 8.
number of oxygens
oxygen has 8 protons
A phosphate group is a larger molecule, where the phosphorus is single bonded to each of the four oxygens, and the other bond of each one of the oxygens is attached to the rest of the molecule, quite probably in a [nucleic acid] chain.
7. Copper, Hydrogen, Sulfur, and 4 oxygens.
8 protons and 8 electrons
THe oxidation number for 'O3' is zero(0). O3 is ozone, and each oxygen atoms forms two single bonds with each of the other oxygens, forming a triangular arrangement.
A xylylene is another name for quinomethane, a compound derived from a quinone by replacing either or both of the quinone oxygens with a methylidene group.
The atomic number of oxygen is 8. So, it has 8 protons always.
- 2 for each O, +3 for each Ni
