[Ar]3d104s2
The noble gas configuration for zinc is [Ar] 3d10 4s2. This means that zinc has the same electron configuration as the noble gas argon, and then has two more electrons in the 4s orbital.
[Kr] 5s2 4d2
Zinc is a transition metal, it is in group 12.
[Ar] 4s2 3d10
Yes, the electron structure of a zinc ion (Zn2+) achieves a pseudo noble gas configuration by losing two electrons to have a full outer shell, similar to a noble gas configuration. This stable electron configuration is in line with the octet rule, making it an example of pseudo noble gas formation.
Yes, the electron structure of a Zinc ion (Zn2+) can be considered an example of pseudo-noble gas formation. When Zinc loses its two valence electrons to become Zn2+, it attains a stable electronic configuration similar to a noble gas (argon) with a completely filled d orbital (3d10) which enhances its stability.
Argon has a full valance shell, an octet, while zinc does not.
Zinc is not a noble gas because noble gases have a full outer electron shell, while zinc only has a full 3d orbital. Noble gases have a stable electron configuration with the maximum number of electrons in their outer shell, making them chemically inert, which is not the case for zinc.
Well, technically it is [Ar]4s^(1)3d^(10), but most people don't recognize the special case that an electron moves up to complete the d shell for zinc. Most people say it is [Ar]4s^(2)3d^(9), but this is incorrect.
Zinc sleeps around too much to be considered noble, so I'd go with Aluminum.
No, it is a noble gas
