To determine the number of protons, electrons, and neutrons for Calcium (Ca) and Neon (Ne), we can follow these steps:1. Identify the Atomic Number: - The atomic number (Z) of an element is equal to the number of protons in
For chlorine Z=17,A =35.Give the number of protons ,electrons and neutrons in (i)chlorine atom ,(ii) chloride ion. View Solution Free Ncert Solutions English Medium NCERT Solutions NCERT Solutions for Class 12 English Medium NCERT Solutions for Class 11 English Medium ...
Atomic number Z represents the number of protons per atom. Mass number Z + N is equal to the number of protons Z plus the number of neutrons N present in the nuclei. Mass numbers of the most abundant isotopes are given in order of decreasing abundance. For example, Cadmium Cd-48 mass ...
While the number of protons will always be the same, with 50 protons in each nucleus, isotopes include different numbers of neutrons in the nucleus.Answer and Explanation: The mass number of tin is 120. As no specific isotope of tin is identified, the common practice is to refer to the ...
