Answer is: B. they are poor conductors of heat.
Ionic compounds are good good electricity and heat conductors, because ionic compounds (for example sodium chloride NaCl) have mobile ions (cations and anions) that are able to transfer electrical charge. This compounds also conduct heat, because the ions are next to each other, so energy can be transferred efficiently from one place to another.
On the other hand, covalent compound (for example methane) are usually bad electricity and heat conductors, because molecules aren far from each other, so heat transfer is less efficient. They do not form ions and atoms are less positive and negative than in ionic compounds.
Answer: 6 valence electrons
Explanation: the valence electrons and group are always the same, but when the group numbers are 10 and above, they would be the first number. For example, every element in group 16 has 6 valence electrons.
a solid material that is typically hard, shiny, malleable, fusible, and ductile, with good electrical and thermal conductivity
Answer:
Green.
Explanation:
Only the particles that hit the nucleus of the atom bounced off.
I think it is c.) the protons from the atom on the right.
