Aluminum number 13 has 13 dots around it.


the electron configuration of Aluminum is # 1s^2 2S^2 2p^6 3s^2 3p^1#

to draw the electron configuration Put Al in the middle of a circle
Place two dots next to the circle and draw a second circle leaving
only the two dots in the interval between the first and the second circles.
Place eight dots in groups of two on the outside of the second circle and draw a third circle leaving the eight dots in the interval between the second and the third circles.
Place three dots evenly spaced ( #120^o#) next to the third circle.
These three dots represent the valance or bonding electrons of Al
