Chapter 2, Problem 46E
Interpretation Introduction
Interpretation:The symbol for an ion with
Concept introduction:In a neutral atom, the number of electrons present are equal to protons. These two are also equivalent to the atomic number in case of neutral atoms.The number of neutrons is calculated by taking the difference in mass number and atomic number. This is because mass number is calculated by taking sum of number of protons and number of neutrons.
