Question

What are elements?

- a chemical substance composed of atoms of two or more different types of atoms

-substances that are made up of only one type of atom

-subatomic particles with a positive charge

- only found on earth

Answer 1

The second option es more than correct

What it basically says is that it's pure, and has never "mixed up" with other elements (which means it's not a compund).


Hope it helped,

Happy homework/ study/ exam!

Answer 2

The accurate answers is:-Substances that are made up of only one type of atom

*A chemical substance composed of atoms of two or more different types of atoms is wrong because this has to do with an compound.

*Subatomic particles with a positive charge is wrong because this has to do with protons, neutrons, and electrons.

*Only found on earth this may be true BUT this doesn't explain what elements are.
