Problem: How many inner/core and how many outer/valence electrons are in Te?a) 46 inner/core and 6 outer/valenceb) 36 inner/core and 12 outer/valencec) 36 inner/core and 6 outer/valenced) 46 inner/core and 12 outer/valence

Tellurium, Te

• Group 6A
• atomic number = 52

Write the ground-state electron configuration.

• Atomic number = Number of electrons = 52 e^-

Distribute electrons in the atomic orbitals:

Recall:

s orbital → can hold a maximum of 2 electrons
p orbitals → can hold a maximum of 6 electrons
d orbitals → can hold a maximum of 10 electrons
 f orbitals → can hold a maximum of 14 electrons
