Question

Both elements and compounds are ____ substances.

Answer 1

Hint: An atom is made up of proton, neutron and an electron. The proton and neutron are present on the nucleus while the electron revolves around the nucleus. The charge on proton is positive, on neutron is zero and on electron is negative.

Complete step by step answer:
1.Element-The simplest chemical substances are known as elements. It properties are-
-It is made up of a single type of atom.
-The atom represents an atomic number which is actually the number of protons present in the nucleus of the atom of that element.
-In an element, each atom has the same number of protons through which the number of neutrons can differ.
-The atoms of an element have similar properties.
-It is a pure substance that cannot be divided into smaller units.
2.Compounds-Two or more elements combine to form a compound. Its properties are-
-It is made up of different types of atoms.
-It is a pure substance that can be divided into smaller units called elements.
-In compounds, the elements are linked by chemical bonds like covalent bond or ionic bond.
-It has different properties than the individual elements from which it is made.
-It contains a fixed ratio of the chemically bonded atoms.

Both elements and compounds are pure substances.

Note:
The elements are divided into three parts-
Metal- has malleability, ductility, luster, magnetic properties and is conductor of electricity and heat.
Nonmetal- is just opposite of the metals. The elements that do not contain the properties of metal come under nonmetals.
Metalloids- have properties of both metal and non-metal.
