Answer: Option (A) is the correct answer.
Explanation:
Nitrogen is a non-metal and it is known that non-metals do not conduct electricity. Thus, it will be least conductive out of the given options.
Whereas antimony (Sb) is a metalloid. Metalloid are the substance that show properties of both metals and non-metals. Thus, antimony will conduct electricity.
On the other hand, bismuth (Bi) is a metal hence, it will conduct electricity.
Thus, we can conclude that the order from least conductive to most conductive will be nitrogen (N), antimony (Sb), bismuth (Bi).
Answer:
B
Explanation:
Because when a cold object is cold it start to get warm because Of the air.
and it start to warm and it gets warm.
Answer:
Ionic compounds contain ions and are held together by the attractive forces among the oppositely charged ions
Explanation:
Common salt (sodium chloride) is one of the best-known ionic compounds. Molecular compounds contain discrete molecules, which are held together by sharing electrons (covalent bonding).
Answer: are electrically attracted to each other
Explanation:Water molecules are attracted to each other by partial negative and positive charges on the oxygen and hydrogen atoms, respectively
Answer:
D. Element.
Explanation:
Atoms form elements. Elements form molecules. Molecules form compounds.
