Atomic structure Practice

List the following atoms and ions in increasing atomic size (small to large).
Provide justification for the specific order you come up with.

The following orbital diagrams are all for the same element, but only one is correct.
Determine if the electron configuration is in the ground state or not. Explain your reasoning.

a) [Kr]  [↑↓]   [↑↓][↑↓][↑↓][↑↓][↑↓]   [↑↓][↑↓][ ]
[math]\qquad\quad 5s \qquad\quad 4d \qquad\qquad\quad5p[/math]

b) [Kr]  [↑↓]   [↑↑][↑↑][↑↑][↑↑][↑↑]   [↑↓][↑↓][↑↓]
[math]\qquad\quad 5s \qquad\quad 4d \qquad\qquad\quad5p[/math]

c) [Kr]  [↑↓]   [↑↓][↑↓][↑↓][↑↓][↑↓]   [↑↓][↑↓][↑↓]
