Semiconductors Silicon is important to the semiconductor manufacturing industry. The three naturally
occuring isotopes of silicon are silicon-28, silicon-29,
and silicon-30. Write the symbol for each.

$-$ Silicon-28: $\frac{28}{14} S$
$-$ Silicon-29: $\frac{29}{14} S$
$-$ Silicon-30: $\frac{30}{14} S$

been describing these isotopes. You put the number of neutrons over the number of products and then put the elements name. So s so this week. 28 hour, 14.9. Reporting through working. But you would have them in a fraction. Form like this. It's 28. Bar 14 s, 29 bar 14. 30 40.
