Which of the following is a difference between naming ionic and covalent compounds? A. In covalent compounds the ending of the second element changes to -ide, but not in ionic compounds.
B. In ionic compounds the ending of the second element changes to -ide, but not in covalent compounds.
C. In covalent compounds, the prefix of the first element is always ignored but the prefix in the second element depends on the
subscript of the element. In ionic compounds, the subscript on each element does not affect the name of the compound.
D. In covalent compounds, the prefix of the first element and second element depends on the subscript of each element. In ionic
compounds, the subscript on each element does not affect the name of the compound. No

a plasma is a warm ionized gasoline consisting of approximately equal numbers of definitely charged ions and negatively charged electrons. the characteristics of plasmas are notably unique from the ones of ordinary neutral gases in order that plasmas are considered a awesome "fourth kingdom of remember."

1.solid

2.carbon dioxide

3.helium

oxygen, selenium, tellurium, and polonium.

they're all from the same group as sulfur (group 16).

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.
