The isotopes are designated to describe different atoms of the same element. To represent a nuclide various notations are used. All notation uses mass number and atomic number or mass number alone. Three types of notations are used. For example, nitrogen atom that contains mass number as 15 is designated as

Concept Introduction:
If the reaction occurs in the nucleus of an atom then it is known as nuclear reaction. These reactions are not considered as ordinary chemical reactions because the electrons do not take part in reaction while the particles inside the nucleus does. Isotope and nuclide are almost similar terms. Isotopes refer to the same element that have different mass number while nuclide refer to atom of same or different elements with specific atomic number and same mass number.

Examine the above data and answer the following questions. a) Explain why some of the elements like TI and Pb on the lower left of the p block are metallic. b) Explain why some of the elements like C, Si in the center of the p block form covalent bonds. Explain why these bonds formed by the network of these elements (as studied in Chapter 25) tend to be unreactive. c) Explain why the noble Group 8A elements are highly unreactive gases. d) Explain why some elements like F, CI, Br etc, on the upper right of the p block are highly reactive nonmetals.arrow_forwardDetermine the mass in grams of 6.42 × 10²¹ atoms of carbon.

- What if there are a different number of Neutrons? Sometimes elements have a different number of neutrons than usual, so therefore have a different atomic mass. This is what we call an Isotope (a variant form of an element which has the same number of protons but a differing number of neutrons). Sometimes we’ll see Isotopes labeled with their new mass like this: 14C = this is Carbon 14. Notice it has a different mass than what is on your periodic table The average mass of all the isotopes is defined as an element’s Atomic Weight. Can you answer questions about these Isotopes?
