d and f BLOCK ELEMENTS

Which of the following best describes the oxidation state behavior of transition vs. non-transition elements?

• Both differ by 1
• Transition: differ by 1; Non-transition: differ by 2
• Both differ by 2
• Both show no specific pattern

What is the oxidation state of Nickel in [Ni(NH₃)₆]²⁺?

• 0
• +1
• +2
• +3

Why is the difference in oxidation states for non-transition elements typically by units of two?

• They are less reactive
• They have fewer electrons
• They gain/lose electrons to complete/half-fill shells
• They only form ionic bonds

What is the oxidation state of Manganese in MnO₂?

• +2
• +3
• +4
• +6

Which of the following is NOT a reason for the decrease in high oxidation state stability beyond Manganese?

• Too many d electrons
• Fewer available orbitals for bonding
• Decrease in atomic size
• Increase in nuclear charge
