Answer: 3
Explanation:
All elements in group 3 have 3 levels of energy.
Na (sodium) has 3 valences the inner has 2 electrons, the middle has 8 electrons and the outer has 1 electron.
This will continue across the group 3 adding one more electron to the outer valence until Ar (argon).
Remember the Octet rule of 8..?

There is no prescribed length of time it takes to photographically document a crime scene. The amount of time spent depends on the size and complication in the crime scene, how much there is to document and environmental factors like weather or danger to the investigative team. It can consist of thousands of photographs and hours of work.
Crime scene photography should not just focus on the obvious. The purpose of crime scene photography is to document what is there and where it is in relationship to the scene, whether it is obviously connected to the crime or not. For example, a photographer in Florida shot the inside of every cabinet and the refrigerator at a homicide scene in a home, just as a matter of procedure. It was later discovered that the victim had a receipt for a six-pack of beer, matching the beer shown in the photograph of the refrigerator. Relatives noted that the victim did not drink beer. Further investigation led the team to the convenience store where the beer was purchased and the surveillance tape showed the victim with an unknown person purchasing the beer. It turns out that the victim had picked up a hitchhiker, purchased beer for that person and come back to the house. The photograph of the refrigerator contents had created the link enabling the investigators to find the suspect.
