Response: The reason for periodicity in Homes is definitely the repetition of similar outer electronic configuration after specified common intervals.
Reply: The molecular orbital shaped by the subtractive effect with the electron waves with the combining atomic orbitals, is termed antibonding molecular orbital.
Conceptual Clarity: Concentrate on clearing your principles just before shifting on to far more sophisticated subjects. This tends to make sure you have an understanding of the foundational topics totally, which happens to be essential for tackling bigger-level queries.
Query 32. Forecast the formulation on the steady binary compounds that could be shaped by The mixture of the next pairs of factors:
Attract a neat diagram with the "Microscopic Composition of the intestinal villus" and label the sections offered beneath :
electron attain enthalpy is unfavorable or constructive it depends upon the nature on the ingredient. One example is. For halogens it is extremely damaging, because they can obtain the noble gasoline configuration by accepting an additional electron.
Answer: Electronegativity: Electronegativity may be the tendency of the atom to appeal to shared set of electrons. It is the house of bonded atom.
Answer: The elements of Group I've only one electron of their CBSE Class 12 Mathematics respective valence shells and so have a powerful tendency to lose this electron. The inclination to shed electrons consequently, relies upon on the ionization enthalpy. Considering that the ionization enthalpy decreases down the group thus, the reactivity of team one aspects will increase in a similar buy Li < Na < K < Rb < Cs.
जसप्रीत बुमराह बने क्रिकेट ऑस्ट्रेलिया के कप्तान, पैट कमिंस और हेड टीम में शामिल नहीं, यशस्वी को मौका
Nuclear charge. Since the nuclear cost increases the attraction for your electron also improves that’s why ionization enthalpy will increase.
To really make it simpler for college students, Extramarks provides the syllabus in the semester-smart fashion so that there's no confusion from the minds of The scholars. By subsequent The brand new ISC 12 syllabus, college students should be able to prepare for their exams correctly and rating higher marks too.
For people aiming to excel inside their reports, it’s vital to remain educated and use trusted examine resources. The myCBSEguide Web site provides the newest syllabus for all CBSE subjects, serving to college students keep aligned Together with the curriculum.
Made in a reasonably very simple language, We've created absolutely sure which the solutions include all the basic ideas. The solutions are hundred percent mistake free, and simply comprehensible.
obtaining no attraction for electron since by accepting electron their configuration will become a lot less steady. In that case Electricity must be supplied to simply accept electron. Hence electron acquire enthalpy are going to be beneficial.
