1) Atomic radius: It increases from left to right in a period
2) Ionic radius: It increases from left to right in a period
3) First ionization energy: It increases from left to right in a period
4) Melting point: Generally decreases from left to right in a period
I’m pretty sure it will be the answer choice B
I think it is A correct me if i am wrong hope this helps
It oxidized cu since it gains electons.
