C. Delocalized Electrons in Metal

Explanation:

Conductivity is the relative ability to conduct heat and electricity. Delocalized electrons in metal interact with an electric field and carry electric currents.

Most covalent and ionic solids are nonconductors because electrons are localized to specific atoms or bonds. Ionic substances can become conductors in a liquid state because the ions can move, which carry the electric current.

from 1609, galileo galilei used the recently invented telescope to observe the sun, moon and planets. he saw the mountains and craters of the moon, and for the first time revealed the planets to be worlds in their own right. galileo also provided strong observational evidence that planets orbited the sun.

his discoveries about the moon, jupiter's moons, venus, and sunspots supported the idea that the sun - not the earth - was the center of the universe, as was commonly believed at the time.galileo turned his gaze toward venus, the brightest celestial object in the sky - other than the sun and the moon.
