Final answer:
The electron configuration for the outermost electrons of elements found in Group IVB is [Ar] 3d2 4s2 for titanium, [Kr] 4d2 5s2 for zirconium, and [Xe] 4f14 5d2 6s2 for hafnium.
Step-by-step explanation:
The electron configuration for the outermost electrons of elements found in Group IVB can be determined by looking at the periodic table. Group IVB consists of elements from the 4th column of the periodic table, which includes titanium (Ti), zirconium (Zr), and hafnium (Hf).
- Titanium has the electron configuration [Ar] 3d2 4s2.
- Zirconium has the electron configuration [Kr] 4d2 5s2.
- Hafnium has the electron configuration [Xe] 4f14 5d2 6s2.
These configurations show the arrangement of the outermost electrons in each element.
