which combination of factors is most suitable for increasing the electrical conductivity of metals?\nmore valence electrons and larger atomic radius\nfewer valence electrons and larger atomic radius\nmore valence electrons and smaller atomic radius\nfewer valence electrons and smaller atomic radius
Answer
Answer:
C. more valence electrons and smaller atomic radius
Explanation:
Step1: Understand conductivity principle
Conductivity in metals is due to free - moving electrons.
Step2: Analyze valence electrons
More valence electrons mean more free - moving electrons available for conduction, increasing conductivity.
Step3: Analyze atomic radius
Smaller atomic radius leads to stronger metallic bonds and more delocalized electrons, enhancing conductivity.
