Question

Please help (: What Argon atom has the following orbital-filling diagram (Figure 1) ?

Answer 1

Here is the diagram

Answer 2

its p block element it should have completely filled p orbits by electrons

Answer 3

That's what I thought, but its an actual question, which atom has that orbital filling diagram... Anyone?

Answer 4

It's not an argon atom

[Ar] is short notation for: \(1s^22s^22p^63s^23p^6\)

Answer 5

oh.... yikes. then what is it?

Answer 6

potassium?

Answer 7

look at the electron count. It has 1 electron in the \(4p_x\) orbital, so it must be in the p block (in period 4).

Answer 8

wow... yup. Looks like it was Gallium. Maybe I should have read the textbook first? Ha ha Thanks guys

Answer 9

It is gallium. That would be a good idea. lol
