Isotopes are members of a family of an element that all have the same number of protons but different numbers of neutrons. The number of protons in a nucleus determines the element’s atomic number on the Periodic Table. For example, carbon has six protons and is atomic number 6.
What isotope has 25 protons and 17 neutrons?
Chemical Elements.com – Manganese (Mn)
What isotope has 46 protons and 48 neutrons?
If you have a chart where you have to label the isotope, you just work backwards… It has 46 electrons which means it has 46 protons.

How do you solve isotope notation?
What are isotopes in class 10th?
An isotope is a variation of an element that possesses the same atomic number but a different mass number. A group of isotopes of any element will always have the same number of protons and electrons.
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 do you write isotope names?
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 isotope has 17 protons and 18 neutrons?
Chlorine-35 has 17 protons and 18 neutrons and occurs in nature about 75% of the time.
What isotope has 17 protons and 20 neutrons?
Chlorine-37, the nucleus of which consists of 17 protons and 20 neutrons, is a different nuclide from sodium-23 (nucleus of 11 protons and 12 neutrons) or chlorine-35 (nucleus of 17 protons and 18 neutrons).
What isotope has 48 neutrons?
Krypton has the chemical formula Kr. The most stable isotope of Krypton has 48 neutrons in its nucleus giving it an atomic mass of 84. Krypton is a Noble Gas.
Which element contains 47 protons?
Silver is a chemical element with symbol Ag and atomic number 47.
What isotope has 32 protons and 30 neutrons?
What isotope has 32 protons and 30 neutrons?
|# of protons||32||32|
|# of neutrons||30||32|
|# of electrons||32||32|
How do a and Z change when isotopes form?
Isotopes are atoms of the same element that have the same number of protons (i.e., atomic number, “Z”) but a different number of neutrons, meaning that their mass number, “A”, varies.
How do you write carbon 12 as an isotope?
Notation for Isotopes of Carbon (C)
How do you draw an isotope?
How to draw an isotope
What is isotopes BYJU’s?
Two nuclides are isotones if they have the same neutron number N, but different proton number Z. For example, boron-12 and carbon-13 nuclei both contain 7 neutrons, and so are isotones . Similarly, 36S, 37Cl, 38Ar, 39K, and 40Ca nuclei are all isotones of 20 because they all contain 20 neutrons. Chemistry.
What are isotopes class11?
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 is an isotope PDF?
Definition of isotope.
Atoms with the same number of protons in the nucleus can have different. numbers of neutrons. Atoms with the same number of protons but different. number of neutrons are isotopes of the same element.
What are isotopes One example?
Example – Carbon 12 and Carbon 14 are both isotopes of carbon, one with 6 neutrons and one with 8 neutrons.
Who discovered isotopes?
Soddy in his lab at the University of Glasgow. In a letter to the editor published in the Dec. 4, 1913, issue of Nature, English radiochemist Frederick Soddy proposed the isotope concept—that elements could have more than one atomic weight. The idea led to his 1921 Nobel Prize in Chemistry.
How many isotopes are there?
There are about 94 elements found naturally on Earth (up to plutonium inclusive), though some are detected only in very tiny amounts, such as plutonium-244. Scientists estimate that the elements that occur naturally on Earth (some only as radioisotopes) occur as 339 isotopes (nuclides) in total.
Which of the following are isotopes?
Isotopes are elements with same atomic number but different mass number. Hydrogen and Deuterium are isotopes with same atomic number but different mass number. Hydrogen have atomic number 1 and mass number 1 where as deuterium have atomic number 1 but mass number 2.
