Question

Q. Give two points of difference between an element and a compound?

Answer 1

$\underline\bold\green{Element}$

➪An element is a pure chemical substance made of same type of atom.

➪An element is represented using symbols.

➪Elements contain only one type of atom. Each atom has the same atomic number i.e., the same number of protons in their nucleus.

$\underline\bold\blue{compound}$

➪A compound contains atoms of different elements chemically combined together in a fixed ratio.

➪A compound is represented using its chemical formula that represents the symbols of its constituent elements and the number of atoms of each element in one molecule of the compound.

➪Compounds contain different elements in a fixed ratio arranged in a defined manner through chemical bonds. They contain only one type of molecule. Elements that compose the compound are chemically combined.

Answer 2

$\large\sf{Element:-}$

•An Element is made up of same kind of atoms

•An element cannot be split by physical or chemical methods.

$\large\sf{compound:-}$

• A compound is obtained from different kinds of atoms.

•A compound can be split into new substances by chemical methods
