Question 8

What does ZEFF stand for?

Answer 8

Z = atomic number. EFF = effective nuclear charge. It is used for finding the balanced electrons. The higher the ZEFF the smaller the atomic or ionic radii.

Question 9

What is the equation to find a ZEFF?

Answer 9

ZEFF = Z (element) - S (inner electrons)
