Question 1
Which of the following statements best explains why transition metals lose electrons from s orbitals before d orbitals?
◦ Electrons in s orbitals are paired.
◦ Electrons from d orbitals are less shielded from the nucleus than electrons in s orbitals.
◦ Electrons from s orbitals are lower in energy than d orbitals.
◦ The d orbitals experience a greater drop in energy when electrons are removed.
Question 2

◦ nonmetals.
◦ semimetals.
◦ metals.
◦ gases.
