Q. 6.95 - An Introduction to General, Organic, and Biological Chemistry

Question

Identify each of the following atoms or ions: $(6.1)$

Step-by-Step Solution

Answer

a. It is Phosphorus $\left({\mathrm{P}}^{3-}\right)$ ion.

b. It is Oxygen $\left(\mathrm{O}\right)$ atom. 

c. It is Zinc $({\mathrm{Zn}}^{2+)}$ ion. 

d. It is Iron $\left({\mathrm{Fe}}^{3+}\right)$ ion. 

Part(a) Step 1: Given information

We need to find out which atom or an ion the given species is.

Part(a) Step 2: Explanation

Ions are electrically charged particles that originate when atoms lose or receive electrons in order to form a stable electron configuration.

In an atom, number of protons is same as number of electrons. 

Given species have $15$ protons which means it's atomic number is $15$. But since it have $3$ extra electrons, it is a Phosphorus data-custom-editor="chemistry" $\left({\mathrm{P}}^{3-}\right)$ ion.

Part(b) Step 1: Given information

We need to find out which atom or an ion the given species is.

Part(b) Step 2: Explanation

Ions are electrically charged particles that originate when atoms lose or receive electrons in order to form a stable electron configuration.

In an atom, number of protons is same as number of electrons. 

Given species have $8$ protons which means it's atomic number is $8$. So, it is a Oxygen atom.

Part(c) Step 1: Given information

We need to find out which atom or an ion the given species is.

Part(c) Step 2: Explanation

Ions are electrically charged particles that originate when atoms lose or receive electrons in order to form a stable electron configuration.

In an atom, number of protons is same as number of electrons. 

Given species have $30$ protons which means it's atomic number is $30$. But since it have $2$ less electrons, it is a Zinc data-custom-editor="chemistry" $\left({\mathrm{Zn}}^{2+}\right)$ ion. 

Part(d) Step 1: Given information

We need to find out which atom or an ion the given species is.

Part(d) Step 2: Explanation

Ions are electrically charged particles that originate when atoms lose or receive electrons in order to form a stable electron configuration.

In an atom, number of protons is same as number of electrons. 

Given species have $26$ protons which means it's atomic number is $26$. But since it have $3$ less electrons, it is a Iron data-custom-editor="chemistry" $\left({\mathrm{Fe}}^{3+}\right)$ ion.
