Ionization energy is the energy needed to remove the most loosely attached electron from an atom. The atom is not connected to any other atoms. The chemical elements to the left of the periodic table have much lower ionization energy. Electron gain enthalpy is the energy required to add an electron in a neutral atom. Because, in most of the cases atom releases energy, the electron gain enthalpies are negative. Fajan’s Law used to predict whether a chemical bond will be covalent or ionic, and depend on the charge on the cation and the relative sizes of the cation and anion. Bond parameters refer to the characterization of covalent bond on the basis of various parameters like bond length, bond angle, and bond enthalpy. Resonance structures: Is defined as difference between actual bond energy and energy of most stable resonating structures. Resonance averages the bond characteristics of a molecule as a whole. Resonance stabilizes the molecule because energy of the resonance hybrid is less than the energy of any canonical forms.In this video we will cover:-

I have exam on 2nd Nov and I am watching mam's vdo instead of quick revision 😂 mam you are phenomenal ❤️

[rishitharr]

Mam your explanation is excellent. For the first time I am understanding chemistry well. Thank you mam.

[mviews]

The way u teach... can't express..in words just osm... keep it up mam..🙃

[aryaneetuhooda]

Bond parameters and fajan rule hua crystal clear because of such diamond like
You are really a very good person...You sacrificed your bright future for our education..
From all the students I am saluting you ...Really love u mam 😍😍😍😘😘😘😘🤩🤩🤩🤩

[sunilkumardubey]

Mam you are like our mother. You are doing lots of hard work for us thanku mam . I think your channel will rise with success stars .once again thanku mam.😇😇😇.gd
