Answer:
in an atom or molecule, no two electrons can have the same four electronic quantum numbers. As an orbital can contain a maximum of only two electrons, the two electrons must have opposing spins.
Answer:
Option C
Explanation:
The answer is option C or "The amount of time it takes to rotate around it's axis is the same amount of time it takes to revolve around Earth."Remember that the Earth and the Moons amount of time to make a full rotation is almost in sync and they're two sides of the moon, one side we do not see and that's because that side is currently faced away from the Earth which is called the dark side of the moon. Each side has two weeks oh night, and two weeks of day because of how long it takes the moon to revolve, so while we have a side towards the Earth which is illuminated by the sun we have another pointing away in the dark.
Hope this helps.
Answer:
I'm not all the way sure but I think it is C
Explanation:
The reason is because an ionic bond essentially donates an electron to the other atom participating in the bond. Also, the C-O I think is polar since it is evenly distributed.
The element that has been oxidized is Al ( Answer A)
Explanation
if the oxidation number of an element is greater in the product side than the reactant side then the element has lost the electrons . This mean that the element has been oxidized.
Al is oxidized because it move from oxidation state Zero(0) in reactant side to oxidation state 3⁺ in product side.
This implies that Al loses 3 electrons.
