Question

Which elements likely conduct electricity well ?

Answer 1

Answer:

Chromium, calcium, and osmium

Explanation:

These elements are metals, considering this, these elements electron shells(orbitals) are further away from the nucleus, with this, their attractions are not as strong as non-metals, so some of their electrons are able to move freely.

When you accumulate many atoms, these metals can form a "sea of electrons"  because they all have loose electrons interacting with each other. This allows easy conduction of heat and electricity.

Answer 2

Answer:

Chromium

Calcium

Osmium

Explanation:

The elements likely conduct electricity well are chromium, calcium and osmium. As these are metals and are observed to be good conductors of heat and electricity. They have extra electrons to donate and hence flow of electrons cause them to be a good conductor of electricity. Rest iodine is a non-metals which is not good conductors of electricity. Carbon is not itself a good conductor but one of its allotrope which is graphite is a good conductor of electricity.
