Concept explainers
Interpretation:
The symbols of three isotopes of silicon, silicon-28, silicon-29 and silicon-30 should be written.
Concept introduction: Semiconductors materials such as silicon, germanium, have electrical properties between conductors and insulators.
Answer to Problem 103A
There are three isotopes of silicon (Si) exist in the nature:
Explanation of Solution
a
There are 4 valence electrons in the outermost shell of the silicon. It shares its electrons with other atoms to from covalent bond.
Where,
