What are isomers and isotopes?
Isotopes are different atoms of the same element. Isomers are different compounds with the same molecular formula. • Isotopes differ from each other due to the number of neutrons, whereas isomers differ from each other due to the arrangement of atoms.
How do we define isomers?
isomerism, the existence of molecules that have the same numbers of the same kinds of atoms (and hence the same formula) but differ in chemical and physical properties.
Which are isomers?
Chemical compounds that have identical chemical formulae but differ in properties and the arrangement of atoms in the molecule are called isomers. Therefore, the compounds that exhibit isomerism are known as isomers. The word “isomer” is derived from the Greek words “isos” and “meros”, which mean “equal parts”.
What are allotropes and isotopes?
An allotrope is one way that atoms can be arranged in a solid. An isotope is one way that protons and neutrons can form the same atomic element. Allotropes are crystals that have a different atomic structure than a different allotrope.
What are isotopes class 10th?
Isotopes can be defined as the variants of chemical elements that possess the same number of protons and electrons, but a different number of neutrons. In other words, isotopes are variants of elements that differ in their nucleon numbers due to a difference in the total number of neutrons in their respective nuclei.
What is isomerism and example?
1. Isomers are molecules that have the same molecular formula, but have a different arrangement of the atoms in space. e.g. 1-pentene and 2-pentene are isomers.
What is difference between isomer and allotrope?
Allotropes can be defined as different types of compounds made out of the same single element but in different chemical formulas and different arrangements. Isomers can be defined as the chemical compounds that have a similar molecular formula but with different structural formulae.
What is diamond and graphite?
Graphite and diamond are two of the most interesting minerals. They are identical chemically – both are composed of carbon (C), but physically, they are very different. Graphite is very soft and has a hardness of 1 to 2 on this scale. Diamonds are the hardest known natural substance and have a hardness of 10.
What is called isotope?
An isotope is one of two or more species of atoms of a chemical element with the same atomic number and position in the periodic table and nearly identical chemical behavior but with different atomic masses and physical properties.
