1. A silver atom would have 47 protons and more neutrons than a cobalt atom and a cobalt atom would only have 27 protons and less neutrons than a silver atom.
2. D. Inert Inert means non-reactive.
3. Neon gas is a Nobel gas on the right side of the periodic table so it is an inert gas and does not react with iron.
4. Mass is neither created or destroyed so as Mr. Carney ran carbon in his body left as carbon dioxide. So the 10 lbs he lost left his body as CO2 through the lungs.

Answer: d: They are poor conductors of heat and electricity
.
Explanation:
Although is common knowledge that metals are characterized by high electrical conductivity and heat conductivity, these properties can be justified by looking at the metallic bonding.
<u>In a metal, the bonding electrons are delocalized over the entire crystal</u>. In fact, metal atoms in a crystal can be imagined as an array of positive ions immersed in a sea of delocalized valence electrons.<u>The mobility of the delocalized electrons makes metals good conductors of heat and electricity.
