Question

Both cu and zn have completely filled 3d atomic orbital cu is considered as transtion element but zn is not explain

Answer 1

Answer:

hlo mate here is ur answer...

Explanation:

Copper and zinc belongs to 3d.

the difference is cu is half filled in terms of S orbital.. so it can change its oxidation state but in zn all are filled so only fixed oxidation state...

so cu is transition and d block but ZN is only d block

hope it helps u dear... ❤

Answer 2

Answer:

Zinc is a transition element as its d shell is still being filled. Cu = 3d10, 4s1 Zn = 3d10, 4s2

So electrons are being added to the inner shell rather than the next block of elements called the p block. It gets a little confusing as the shells do not get filled in a sequential order, when the d and s shells are full the p shell is next the next one and the first of the p block elements is gallium. which is not a transition element.
