<span>Oxygen obey the octet rule when reacting to form compounds by adding 2 electrons. Its means the charge on Oxygen is -2.
</span>It has oxidation state −1 is found in a few compounds such as <span>peroxides.</span>
The relative atomic mass of an element is defined as the weight in grams of the number of atoms of the element contained in 12.00 g of carbon-12. To calculate the relative atomic mass of chlorine, the average mass of one atom of chlorine is found by considering 100 atoms of chlorine.
You can find the relative atomic mass by adding the number of protons to the number of neutrons for specific consideration. For example, a carbon-12 atom has 6 protons and 6 neutrons, and so has a relative atomic mass of 12.
I hope this helps
Answer:
A.
Explanation:
The sun unevenly hits the Earth, causing wind to form and move around the poles; never constant.
