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.

What is an isotope and example?

Isotopes are different species of atoms of an element that have different atomic masses. For example, there are three isotopes of carbon: Carbon-12, Carbon-13, and Carbon-14. They have atomic masses of 12, 13, and 14, respectively.

What are isotopes Class 9?

Isotopes: Isotopes are atoms with the same number of protons but that have a different number of neutrons. Since the atomic number is equal to the number of protons and the atomic mass is the sum of protons and neutrons, isotopes are elements with the same atomic number but different mass numbers.

What are 2 examples of isotopes?

The number of nucleons (both protons and neutrons) in the nucleus is the atom’s mass number, and each isotope of a given element has a different mass number. For example, carbon-12, carbon-13, and carbon-14 are three isotopes of the element carbon with mass numbers 12, 13, and 14, respectively.

What is 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 are isotopes Class 11?

Isotopes are the atoms of an element which have the same number of protons but different numbers of neutrons. In other words, you can say that the isotopes have the same atomic number, as the number of protons remain the same, but they have different atomic masses due to the different number of neutrons.

What are isotopes Class 12?

Isotopes are the atoms in which the number of neutrons differs and the number of protons is the same. From the above definition of atomic mass and the atomic number, we can conclude that isotopes are those elements having the same atomic number and different mass numbers.

What are isotopes by Brainly?

Answer. Answer: an isotope is an element with similar chemical properties and the same atomic number, but different atomic weights to another or others. An example of an isotope is Carbon 12 to Carbon 13.

How are isotopes defined Brainly?

Answer: Isotopes are atoms with the same number of protons but that have a different number of neutrons. Since the atomic number is equal to the number of protons and the atomic mass is the sum of protons and neutrons, we can also say that isotopes are elements with the same atomic number but different mass numbers.

What are isotopes Toppr?

The atoms belonging to the same element, having same atomic number Z, but different mass number A, are called isotopes. For example, carbon-12, carbon-13 and carbon-14 are three isotopes of the element carbon with mass numbers 12, 13 and 14 respectively.

What is isotopes and isobars Class 11?

Isotopes are atoms with the same number of protons but differing numbers of neutrons. Isobars are atoms of different chemical elements having equal values for atomic mass. Isotopes have the same atomic number. Isobars have different atomic numbers. Isotopes have a different atomic mass.

What is meant by isotope and isobar?

Isotopes are atoms of the same element. Isobars are atoms of different elements. They have the same atomic number but different mass number. They have different atomic numbers but same mass numbers. Number of protons and electrons in isotopes are the same .

What are 3 isotopes?

(The word isotope refers to a nucleus with the same Z but different A). There are three isotopes of the element hydrogen: hydrogen, deuterium, and tritium. How do we distinguish between them? They each have one single proton (Z = 1), but differ in the number of their neutrons.

How do you write isotopes?

To write the symbol for an isotope, place the atomic number as a subscript and the mass number (protons plus neutrons) as a superscript to the left of the atomic symbol. The symbols for the two naturally occurring isotopes of chlorine are written as follows: 3517Cl and 3717Cl.

What are isotopes Class 9 Byjus?

An isotope is any form of a chemical element that has the same number of protons in the nucleus, or the same atomic number, but has a different number of neutrons in the nucleus.
