Chapter U1.19, Problem 11E

Interpretation Introduction

Interpretation:

The symbol of an ion with 22 protons, 24 neutrons and 18 electrons needs to be determined.

Concept introduction:

Cations have lesser electrons as compared to protons. Number of protons will give the atomic number from which the symbol of the element can be obtained.

Answer to Problem 11E

Symbol of the ion is Ti^{4 +} .

Explanation of Solution

There are 22 protons, so atomic number is 22 which represents titanium element. There are 4 electrons less as compared to protons. The removal of electrons results in the formation of positive charge. So it will be a tetrapositive ion. So it will be Ti^{4 +} .

Conclusion

The symbol of the ion is Ti^{4 +} .
