Respond to: sigma-bond is more robust. It is because sigma-bond is fashioned by head-on overlapping of atomic orbitals and Π bond is fashioned by aspect wise overlapping.
Response: The outer shell electrons are shown as dots bordering the image of the atom. These symbols are often called Lewis symbols or Lewis buildings.
These obtainable examine elements are very adequate to excel in your ISC Board tests. In order to download them immediately and rely on them to arrange to your board examinations simply. One-way links are given earlier mentioned.
(b)The greatest increase in ionization enthalpy is experienced on removal of electrons from Main noble gasoline configuration.
College students who want to have an comprehension of the syllabus, in addition to ICSE methods, can accessibility your complete curriculum on Extramarks. Students will see the syllabus for each and each subject matter in class twelve on the website.
The list of topics for which the CISCE has up-to-date the curriculum was just built general public. This program materials is for that ISC 2024 exam.

Atomic size. As the scale of the atom improves, the space concerning its nucleus along with the incoming electron also improves. Consequently, the power of attraction involving the nucleus as well as the incoming electron decreases and that's why the electron get enthalpy gets much less unfavorable.
(b) The sort of enamel shown in the supplied figure has only one root. Hence This is a canine or incisor that is certainly used to Chunk or pierce.
Response: The elements in a group have very same valence shell Digital configuration and for this reason have identical Actual physical and chemical Homes.

This chapter specials with the value of chemistry in everyday life, mainly drug motion, drug classification and makes use of, as well as the concentrate on interaction, as well as chemicals in food items and cleaning brokers.
Issue 38. Describe the hybridisation in case of PCl5. Why are definitely the axial bonds lengthier ICSE Class 11 Physics in comparison with equatorial bonds?
Reply: When two atoms with various electronegativity are joined to each other by covalent bond, the shared electron pair is not going to inside the centre because of the distinction in electronegativity. For instance, in hydrogen flouride molecule, flouride has higher electronegativity than hydrogen.
