Please help with the following tables. I also need explanation so that I could do it on my own. Thank you!

TABLE 1: EXCEPTIONS TO AUFBAU

Partially filled sublevels are less stable than half-filled sublevels which are less stable than full sublevels.

Some atoms will promote an electron to either half-fill or fill a sublevel.

24Cr	Order electrons fill
	Exceptional configuration
29Cu	Order electrons fill
	Exceptional configuration
47Ag	Order electrons fill
	Exceptional configuration

TABLE 2: ELECTRON CONFIGURATIONS FOR IONS

Cations take away an electron for every unit of positive charge.

Anions add an electron for every unit of negative charge.

Use your periodic table marked with the s, p, d, and f, blocks.

Os (abbreviated)

Pb (full)

I^- (remember this is an ion!)

Sc (orbital diagram)

Rb⁺ (ion)

Mo (exception)
