Fill in the orbital diagram for Boron (Z=5), and determine its highest filled energy level, period, valence electrons, inner electrons, valency, and group number.

Here are the completed details for each element:

For $^{5}\text{B}$ (Boron, Z=5):

• Orbital Diagram:
  • 2p: $\boxed{\uparrow \quad} \boxed{\quad} \boxed{\quad}$
  • 2s: $\boxed{\uparrow \downarrow}$
  • 1s: $\boxed{\uparrow \downarrow}$
• (1) highest filled energy level = 2
• (2) period = 2
• (3) valence electrons = 3
• (4) inner electrons = 2
• (5) valency = 3
• (6) group number = 13
