Question

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

Short 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.

Step-by-step solution

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 Irondata-custom-editor="chemistry" $\left({\mathrm{Fe}}^{3+}\right)$ ion.
