Periodic Properties-7-Best IIT-JEE ,NEET Coaching In Varanasi.

Uncategorized

“Periodic Properties-7” could refer to the seventh part of a series on periodic properties, likely focusing on trends in the periodic table, such as atomic radius, ionization energy, electronegativity, etc. Here’s a brief overview of the periodic properties that might be covered: Best IIT-JEE ,NEET Coaching In Varanasi.

1. Atomic Radius

  • Trend Across a Period: Atomic radius decreases from left to right across a period due to the increasing nuclear charge, which pulls electrons closer to the nucleus. Best IIT-JEE ,NEET Coaching In Varanasi.
  • Trend Down a Group: Atomic radius increases down a group as additional electron shells are added, increasing the distance between the nucleus and the outermost electrons. Best IIT-JEE ,NEET Coaching In Varanasi.

2. Ionization Energy

  • Definition: The energy required to remove an electron from an atom in its gaseous state.
  • Trend Across a Period: Ionization energy increases across a period as the effective nuclear charge increases. Best IIT-JEE ,NEET Coaching In Varanasi.
  • Trend Down a Group: Ionization energy decreases down a group due to the increasing distance of the outer electrons from the nucleus and increased shielding effect. Best IIT-JEE ,NEET Coaching In Varanasi.

3. Electronegativity

  • Definition: The tendency of an atom to attract electrons in a chemical bond. Best IIT-JEE ,NEET Coaching In Varanasi.
  • Trend Across a Period: Electronegativity increases across a period as atoms have a greater desire to fill their valence shells. Best IIT-JEE ,NEET Coaching In Varanasi.
  • Trend Down a Group: Electronegativity decreases down a group because of the increased distance of the valence electrons from the nucleus. Best IIT-JEE ,NEET Coaching In Varanasi.

4. Electron Affinity

  • Definition: The energy change when an electron is added to a neutral atom in the gaseous state.
  • Trend Across a Period: Generally, electron affinity becomes more negative (indicating a stronger attraction for added electrons) across a period. Best IIT-JEE ,NEET Coaching In Varanasi.
  • Trend Down a Group: Electron affinity becomes less negative down a group due to the increasing distance of the added electron from the nucleus. Best IIT-JEE ,NEET Coaching In Varanasi.

5. Metallic Character

  • Trend Across a Period: Metallic character decreases across a period as elements become more non-metallic in nature. Best IIT-JEE ,NEET Coaching In Varanasi.
  • Trend Down a Group: Metallic character increases down a group as elements become more metallic in nature. Best IIT-JEE ,NEET Coaching In Varanasi.

6. Non-Metallic Character

  • Trend Across a Period: Non-metallic character increases across a period. Best IIT-JEE ,NEET Coaching In Varanasi.
  • Trend Down a Group: Non-metallic character decreases down a group. Best IIT-JEE ,NEET Coaching In Varanasi.

7. Reactivity of Metals and Non-Metals

  • Metals: Reactivity decreases across a period and increases down a group.
  • Non-Metals: Reactivity increases across a period and decreases down a group. Best IIT-JEE ,NEET Coaching In Varanasi.
