Write the nuclear symbolChapter 19, Problem 94AP, . Zirconium consists of five primary isotopes, of mass numbers and abundances shown below: Zr-90 % for each of these isotopes of

zirconium.

Interpretation Introduction

Interpretation:

Interpret the symbol for isotope of Zr-90, Zr-91, Zr-92, Zr- 94, Zr-96.

Concept Introduction:

The modern periodic table is arranged according to the atomic number of the element and the symbol of the elements is given in the periodic table. Periodic table consist of 18 group and 7 period. Atomic number is equal to the number of protons. Mass number is equal to the sum of number of proton and number of neutrons.

Like: Sodium: Symbol-Na, Atomic number-11.

Explanation

Isotopes are atoms of same element with same atomic number but different mass number. Here, atomic number is equal to number of protons and electrons in the ground state of an atom and mass number is equal to sum of number of protons and neutrons present in the nucleus of the atom.

The general atomic symbol of an atom is as follows”:

ZAX

Here, X is atomic symbol of the element. A is mass number and ZX is atomic number.

Zr is the symbol for zirconium and having atomic number or number of protons 40
