One isotope of a metallic element has mass number 74 and has 51 neutrons in the nucleus. An atomic ion has 18 electrons. Write the symbol for this ion (give the symbol for the nucleus and give the ionic charge as a right superscript).

Interpretation Introduction

Interpretation:

The symbol of the given atomic ion has to be written.

Concept Introduction:

All the elements is expressed in form of symbol.  This is easy to use instead of writing the name of element every time.  Same way, the ion that is formed from the neutral atom either by addition of removal of electrons can also be represented as symbols.

Explanation of Solution

The nucleus of the atom under consideration has a mass number of 74.  The nucleus contains 51 neutrons.  This means the atomic number of the element under consideration is 23 (obtained by subtraction of 51 from 74).  The element that corresponds to the atomic number 23 is Vanadium.

In the problem statement it is given that the atomic ion contains 18 electrons.  The total number of protons (atomic number) present in the element is 23.  Therefore, from this the ionic charge can be found out.

Ionic charge  = number of protons -&
