I'm pretty sure the moon would be a crescent within the 10 day period because it takes about 28 days for the moon to go through the different stages.
Answer:
Na⁺
Explanation:
In the given atom:
Number of protons = 11
Number of neutrons = 12
So, the number of electrons = 10
The number of protons within an atom is used to determine the kind of atom we have been given.
Since the number of protons is the same as the atomic number, here the atomic number is 11 and this is Sodium .
In this sodium atom, the number of protons is more than the number of electrons;
Charge = number of protons - number of electrons = 11 - 10 = +1
So, we have a Na⁺
