Q. 4.84 - An Introduction to General, Organic, and Biological Chemistry

Question

Complete the following table for the three naturally occurring isotopes of silicon, the major component in computer chips: $\left(4.4,4.5\right)$

Step-by-Step Solution

Answer

The table in question is completed below.

		Isotope
	${}_{14}{}^{28}Si$	${}_{14}{}^{29}Si$	${}_{14}{}^{30}Si$
Atomic Number	14	14	14
Mass Number	28	29	30
Number of Protons	14	14	14
Number of Neutrons	14	15	16
Number of Electron	14	14	14

Step 1: Given information

We need to complete the table which we have given in the question.

Step 2: Simplify

Isotopes$\to \begin{array}{c}28\\ 14\end{array}Si\to \begin{array}{c}29\\ 14\end{array}Si\to \begin{array}{c}30\\ 14\end{array}Si$   

		Isotope
	${}_{14}{}^{28}Si$	${}_{14}{}^{29}Si$	${}_{14}{}^{30}Si$
Atomic Number	14	14	14
Mass Number	28	29	30
Number of Protons	14	14	14
Number of Neutrons	14	15	16
Number of Electrons	14	14	14

$\begin{array}{c}A\\ z\end{array} X$

z- atomic number

A- mass number

Number of electron= Number of proton = Atomic number

Number of neutron= mass number-number of proton
