1AlBr3+ 3K ---> 3KBr + 1Al
Answer:
Here's what I get
Explanation:
The ionization energy (I) is the energy required to remove an electron from an atom in the gaseous phase.
You can remove electrons in succession and measure the energies required as I₁, I₂, I₃, etc.
Thus, the removal of two electrons from Cu gives you Cu²⁺.
I found the ionization energies of Cu and used them to create those of Cu²⁺ (see table and graph below).
The electron configuration of Cu²⁺ is
Cu²⁺: 1s² 2s²2p⁶ 3s²3p⁶ 3d⁹
You can remove the nine 3d electrons and then there is a sudden jump from I₉ to I₁₀ as you break into the filled [Ar] configuration.
Similarly, there is big jump from I₁₇ to I₁₈ as you break into the filled [Ne] configuration.

First, we have to find the chemical formula for zinc ion and phosphate ion.
Zinc ion is a cation, and its formula is Zn^2+,
This is because zinc atom requires 2 outer shell electrons to be removed in order to become stable.
On the other hand, phosphate ion is a anion, and its formula is PO4^3-.
In order to find the chemical formula of this ionic bond, we need to make sure their charges are balanced.
To do this, take 2+ and 3-, their least common multiple is 6, so in order to turn both charges into 6+ and 6-, we need to determine how many of that ion is needed.
So to make 2+ to 6+, we need 3 zinc ions ( +2 x 3 = 6).
And to make 3- to 6-, we need 2 phosphate ions (-3 x 2 = - 6).
Now we can just combine the chemical formulas with the number of that ion needed (you can ignore the charge)
Therefore, your answer should be Zn3(PO4)2.
Because the modern periodic table is according to icnreasing atomic numbers.Ar has the atomic number 18 and potassium 19 so Argron is placed before K in the Modern periodic table.
