What do you call elemente with th

Explanation:

Atoms are made of 3 parts.

- The protons and Neutrons form together creating a sun, or nucleus at the center

- The electrons orbit this sun like planets.

The element with Th is Thorium. It is a metallic chemical element that when exposed to air, hardens.

metals are good conductor of electricity. it has free electrons on their surface. according to electron pool theory, each atom present in a metal crystal losses all of its valence electron and as a result a pool of free is form. these pool of electrons are free to move and   conduct electricity easily   while making metal as good conductor.

the correct answer is a. the ability of electrons to flow throughout the metal.
