someone please tell the important questions of chapter Atomic Structure ( class 11 )

${\red{\underline{\underline{\bold{AnsweR:-}}}}}$

Short Answer Type Questions:-

Q .1 Arrange s, p and d sub-shells of a shell in the increasing order of effective nuclear charge (Zeff) experienced by the electron present in them.

Q.2 Show the distribution of electrons in oxygen atom (atomic number 8) using orbital diagram.

Q.3 Nickel atom can lose two electrons to form Ni2+ ion. The atomic number of nickel is 28. From which orbital will nickel lose two electrons.

Q.4 Which of the following orbitals are degenerate? 3dxy, 4dxy, 3dz2, 3dyz, 4dyz, 4dz2

Q.5 Calculate the total number of angular nodes and radial nodes present in 3p orbital.

Long Answer Type Questions:-

Q. 1. What is photoelectric effect? State the result of photoelectric effect experiment that could not be explained on the basis of laws of classical physics. Explain this effect on the basis of quantum theory of electromagnetic radiations.

Q.2 Calculate the energy and frequency of the radiation emitted when an electron jumps from n = 3 to n = 2 in a hydrogen atom.

Q.3 Why was a change in the Bohr Model of atom required? Due to which important development (s), concept of movement of an electron in an orbit was replaced by, the concept of probability of finding electron in an orbital? What is the name given to the changed model of atom?

hope it helps you..

Answer 2

Explanation:

put briefly and simply the atomic structureof a compound is a key of components to understaning the reactivity and behavior of chemicals.......

just by looking at the structure of the molecule ,a chemist can be predict many things about to chemical such as,;boiling and metallic points..
