How are isotopes different from allotropes?

Answer 1

An allotrope is one of two or more distinct forms of an element . Two allotropic forms of the element carbon are-

1.Diamond

2.Graphite

Answer 2

Isotopes are atoms for the same element, with differing numbers of neutrons.

Allotropes are molecules with the same atoms, arranged differently within the molecule.

More Information:

An Isotope is a variant form of an atom of the same element which carries a different Atomic Mass. This is because isotopes carry extra neutrons in their nuclei. For example, there are 3 isotopes of carbon: Carbon-12, Carbon-13, and Carbon-14. The numbers refer to the approximate atomic mass of each isotope.

An allotrope is a variant form, in the same state, of an elementary material. For example, diamonds, buckyballs, and graphite are each a form of carbon, but the pattern of the arrangement of the carbon atoms is different in each form. These different forms are allotropes of carbon.

Answer 3

ALLOTROPES :

We know that an element consists of same type of atoms. However, there are certain types of elements like carbon, sulfur and phosphorus in which different arrangement of atoms give them different physical forms. These different arrangement of atoms impart different physical properties to the element. However, chemical properties remain the same. These different physical forms of the same element having different physical properties but same chemical properties are called Allotropes and this property is called Allotropy.

ISOTOPES :

Isotopes are variants of atoms of a particular chemical element, which have differing numbers of neutrons. Atoms of a particular element by definition must contain the same number of protons but may have a distinct number of neutrons which differs from atom to atom, without changing the designation of the atom as a particular element. The number of protons and neutrons in the nucleus, known as the mass number, is not the same for two isotopes of any element. For example, C-12, C-13 and C-14 are three isotopes of the element carbon with mass numbers 12, 13 and 14 respectively. The atomic number of carbon is 6 (every carbon atom has 6 protons); therefore the neutron numbers in these isotopes are 6, 7 and 8 respectively. The atoms of the same element having same atomic number but different mass number are called Isotopes.

From the above mentioned, one can easily understand the difference between allotropes and isotopes.

Answer 4

Isotopes are atoms having the same number of protons but a different number of neutrons.
Allotropes are different structural configurations (bonding of atoms) of chemical elements.
