Match the element with its description. match      term          definition                 potassium          a) great conductor of heat and electricity                 barium                b) has properties of both metals and nonmetals                   boron                  c) malleable and highly reactive                   neon                    d) nonreactive gas

Potassium = Great conductor of heat and electricity

Neon = Non reactive

Boron = has properties of both metals and non metals

Barium = Malleable and highly reactive

Explanation:

Potassium = Great conductor of heat and electricity

Potassium is soft metal and has low melting point. It is white silvery luster with great heat conducting properties.

Neon = Non reactive

Neon is present in group eighteen. It is noble gas. Its outer electronic shell is completely filled that's why it is non reactive.

Boron = has properties of both metals and non metals

Boron is metalloid and behave like both metals and non metals.

Barium = Malleable and highly reactive

Barium is belong to group 2A. It is alkaline earth metal. It is highly reactive towards other elements such as oxygen, fluorine, chlorine , etc.

answer: 2

explanation:

yes

4.) metal

"-the movement of carbon from the nonliving environment into living things and back to the environment

-carbon is the essential component of proteins, fats, and carbohydrates (which make up all organisms)

-carbon exists in air, water, and living organisms

-producers convert carbon dioxide in the atmosphere into carbohydrates during photosynthesis

-bacteria in the atmosphere cycles through the system in filtration units

-in cellular respiration, carbon is released back into the atmosphere as carbon dioxide

-some carbon is stored in limestone (forming one of the largest "carbon sinks" on earth)

-largest carbon reservoir on earth= limestone

-carbon stored in the bodies of organisms as fat, oils, or other molecules may be released into the soil or air when the organism dies

-this may form deposits of coal, oil, or natural gas (fossil fuels, which increased the atmospheric carbon dioxide)

-fossil fuels store carbon left over from bodies of organisms that died millions of years ago

-they are located in the surface of earth, deep within the earth and beneath the ocean floor."
