c.it can be separated through chemical process.
d.it is composed of two or more types of atoms.
Answers
Answer:A
Explanation:
Answer:
Element is- the simplest substances
Explanation:
An element is a substance that cannot be broken down into any other substance. Every element is made up of its own type of atom. This is why the chemical elements are all very different from each other.
A material consisting of only one type of atom. Elements are pure substances that cannot be broken down further by physical means.
Elements are chemically the simplest substances and hence cannot be broken down using chemical reactions. Elements can only be changed into other elements using nuclear methods. Although an element's atoms must all have the same number of protons, they can have different numbers of neutrons and hence different masses. Note that an element: consists of only one kind of atom, cannot be broken down into a simpler type of matter by either physical or chemical means, and. can exist as either atoms (e.g. argon) or molecules (e.g., nitrogen).
The properties of elements are: Element is made up of one kind of atom. Elements combine to form compounds. They cannot be broken down into two or more simple substances by physical means or by chemical means.
