Text Solution

AI Generated Solution

To explain why the first ionization energy (IE₁) of nitrogen (N) is higher than that of oxygen (O), we can follow these steps: ### Step 1: Define Ionization Energy Ionization energy is the amount of energy required to remove the most loosely held electron from a gaseous atom to form a gaseous ion. The first ionization energy (IE₁) specifically refers to the energy needed to remove the first electron. ### Step 2: Understand Electronic Configurations - **Nitrogen (N)** has the electronic configuration: - 1s² 2s² 2p³ ...

Explain why : The second ionisation energy of Li is very high.

Choose the correct pair regarding ionisation energy (IE_(1))

The second ionisation energies are higher than the first ionisation energies. This is mainly due to the fact that after the removal of the first electrons, the atom changes inot mono valent position ion. In the ion, the number of electrons decreases but the nuclear charge remains the same. As a result of this, the remaining electrons are held more tightly by the nucleus and it becomes difficult to remove the second electron . Therefore, the value of second ionisation energy . (IE_(2)) , is greater than that of the first ionisation energy (IE_(1)) . Similarly third ionisation energy (IE_(3)) is greater than that of second IE_(2) . Successive ionisation energy of an atom is greater than previous one, because

Why is the ionisation energy of lead slightly higher than that of tin?

The second ionisation energies are higher than the first ionisation energies.
