A pure element unbound or in a diatomic state, such as cl2, always has an oxidation number of 0 (zero).
<h3>Why does pure element or a diatomic molecule has zero oxidation state?</h3>
In a neutral substance with atoms of only one element, the oxidation number of an atom is zero. As a result, the oxidation number of the atoms in O2, O3, P4, S8, and aluminum metal is 0. The oxidation numbers for an element in its normal state will be zero. O2 and Cl2 are diatomic gas molecules that occur naturally, thus when they are in that state, they have an oxidation state of zero. Metals like zinc will also have an oxidation number of zero if they are in their natural solid state.
O2 and Cl2 are neutral diatomic, hence they will always have a zero oxidation state. It is impossible for one oxygen atom to have a negative 2 charge while the other has a positive 2. The oxidation states should be 0 if the elements are solids, liquids, or any type of diatomic molecule.

The answer is solute, solvent
<span>In a solution, a solute the component which is present in lesser amount while a solvent is present in greater amount. </span>Since nitrogen is present in a greater amount than oxygen (78% > 21%), then the oxygen must be the solute and the nitrogen must be the solvent in the air.
16.00 grams of oxygen
since in one mole the mass would be the molecular mass, which is found on the periodic table
Answer:
The sun is heavier than all of the planets, thus having more gravity
Explanation:
Because the sun is heavier, it exerts more gravitational pull towards itself, thus keeping all of the planets in orbit.
