From 20 minutes to 45 minutes one can practice yoga which includes Asanas and pranayama and meditation

you should listen to your body to do yoga, how you are feeling while doing yoga , are you getting tired? or not. i would prefer you to do yoga in morning only but you can do pranayam twice a day for good montel health.

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.

🔹 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)

Energy required to remove an electron from a neutral atom (in gaseous state) is called ionisation potential. 

Meaning: Higher IP → atom holds electrons tightly.

Energy change when an atom gains an electron (forms an anion) is called electron affinity 

Meaning:Higher (more negative) EA → atom strongly attracts electrons.
