Answer:
because the product of CuO contains 2 molecules so it is unbalanced
Explanation:
to balance it 2Cu+2O=4CuO now it is balanced
Answer:
A
Explanation:
Nitrogen is an atom made up of 7 electrons.
To draw the orbital energy level diagram, let us write the orbital notation of the atom;
7 electrons of Nitrogen:
1s² 2s² 2p³
So,
The orbital notation diagram is :
1s² 2s² 2p³

Because mass is not always the same for objects made from the same material. Just because an object has the same mass as another doesn’t mean they are the same material.
So potassium<span> is </span>more<span> reactive </span>than<span> lithium because the outer electron of a </span>potassium<span> atom is </span>further<span> from its nucleus </span>than<span> the outer electron of a lithium atom.</span>
