Question

Isotopes of an element have :

• A. identical chemical properties
• B. slightly different physical properties
• C. very different half-life
• D. all of the above

Answer 1

Answer: (D)

all of the above

Isotopes of an element have :

• identical chemical properties
  
• slightly different physical properties
  
• very different half-live
  

Since the isotopes have the same number of valence electrons, they have identical chemical properties. Since they have different masses, they have slightly different physical properties. Since their nuclear structures are different, they have very different half life.
