An element that has a low first ionization energy and good conductivity of heat and electricity is classified as a
(1) metal (3) nonmetal
(2) metalloid (4) noble gas

(1) Metal

All metals ionize easily, ex. Sodium forms Na+ easily as it has a very low first ionization energy, and all metals easily conduct electricity as they are very good at ionization and can thus move electrons from one atom to another. 

It’s the energy source of stars

Hey how did you manage to type such a big lab report
