Answer from: simreg5230

texture

Explanation:

Elements have been classified into three categories namely; metals, non-metals and metalloids. This classification was done based on certain characteristics or properties possessed by each element. Some of the characteristics used are: lustre, malleability, conductivity, melting point, boiling point etc.

- Metals are very good conductors of heat and electricity whereas metalloids and nonmetals are not.

- Metals and metalloids shine when polished i.e. they are lustrous, whereas nonmetals don't

- Metals are malleable i.e. can be beaten into sheets.

Texture is not a property used to classify metals and metalloids.

answer: carbon 14 can only be used to determine the age of the organisms that were once living, and igneous rocks are non living.

explanation:

carbon 14 dating is used to determine the age of the sample by estimating the amount of carbon 14 present in the sample and then comparing it with a reference standard.carbon 14 is a isotope of carbon which is radioactive and unstable. carbon 14 is assimilated by all plants and animals throughout their life from carbon dioxide. however, one the organisms die they stop this assimilation and the carbon 14 content starts to decrease.by knowing how much of carbon 14 is left in an organism after his death, one can estimate the age of the organism. the materials whose age can be estimated by carbon 14 method are the organic compounds. however, some inorganic compounds such as aragonite shell can also be dated.however, if we consider the igneous rocks it is a non living component which never accumulated carbon 14 in it and thus, we cannot use carbon 14 dating method to estimate its age.
