Sunsets, focus on being consistent more than the time. If you can practice consistently, you will automatically create a habit which will be beneficial to you. Stay youthful with yoga🧘‍♀️

Parents are not rejecting online tuition completely, but they have concerns about discipline, monitoring, and effectiveness. Many students get distracted at home, and parents feel there is less accountability compared to offline classes. There is also limited interaction, higher screen time, and a perception that offline tuition gives better results and seriousness.

Maximum amount of energy required to remove the most loosely bounded electron ( valence shell electron) from an isolated gaseous atom from its ground state, resulting in a cation is called ionisation energy.Ionisation energy is always endothermic ( energy is required ).Electron affinity is the amount of energy released when one mole of electrons will be added into valence shells of one mole isolated gaseous atoms to convert them into one mole mono-negative gaseous ions ( anions ).

Electron affinity (EA) = Energy released to add one electron

🔹 Ionisation Potential (Ionisation Energy)

Definition: The energy required to remove an electron from an isolated gaseous atom.

Process:

Atom → Cation + electron

Nature: Always positive (energy is absorbed).

Example:

Na → Na⁺ + e⁻ (energy is needed)

👉 It tells how strongly an atom holds its electrons.

🔹 Electron Affinity

Definition: The energy change when an electron is added to an isolated gaseous atom.

Process:

Atom + electron → Anion

Nature: Usually negative (energy is released), but can be positive for some elements.

Example:

Cl + e⁻ → Cl⁻ (energy is released)

👉 It tells how much an atom wants to gain an electron.

🔁 Key Differences

Feature

Ionisation Potential

Electron Affinity

Meaning

Removal of electron

Addition of electron

Energy change

Energy absorbed

Energy released (mostly)

Sign

Positive

Negative (generally)

Forms

Cation

Anion

Indicates

Tendency to lose electron

Tendency to gain electron

🎯 Easy Way to Remember

Ionisation Potential = “Pulling electron out” (needs energy)

Electron Affinity = “Pulling electron in” (releases energy)
