What is the primary reason for the high electrical and thermal conductivities of alkaline earth metals?

Options

  1. AHigh ionization energies
  2. BHigh melting points
  3. CPresence of free electrons in the metal lattice
  4. DSmall atomic sizes

Correct answer

C. Presence of free electrons in the metal lattice

Step-by-step solution

The high electrical and thermal conductivities of metals are primarily due to the presence of free electrons in the metal lattice that can move freely and carry electrical and thermal energy.
