The following are important topics covered in NCERT Solutions Class 11:

Classification of Elements and Periodicity in Properties - Elements are classified into various categories to facilitate element study. Many attempts were made to classify elements, such as Dobereiner's Triads and Newland's Octave. 

o   Dobereiner's Triads - Johann Wolfgang Dobereiner, a German chemist, was the first to attempt to group elements with similar properties into groups of three elements. Dobereiner's triad was the name he gave to these groups. In his triads, Dobereiner explained that the atomic mass of the middle element would be roughly equal to the average of the atomic masses of the other two elements in the triad.

o   Newland's Octave - John Newlands, an English scientist, attempted to arrange 56 known elements in increasing order of atomic mass. Every eighth element, according to Newland, exhibited properties similar to the first.

o   Mendeleev's periodic table - In 1869, Dmitri Ivanovich Mendeleev presented his periodic table. He discovered that the physical and chemical properties of elements were related to their atomic mass on a regular basis. Need to Classify Elements - During the nineteenth century, many new elements were discovered, making it difficult to study each one individually. To address this issue, intellectuals proposed organizing the elements.

·        Need to Classify Elements - During the nineteenth century, many new elements were discovered, making it difficult to study each one individually. To address this issue, intellectuals proposed organizing the elements.

·        Modern Periodic Law and the Current Form of the Periodic Table - The elements in the modern periodic table are arranged in a periodic function of their atomic number based on their physical and chemical properties.

·        Elements with Atomic Numbers Greater Than 100 - The periodic table contains approximately 118 elements. In most cases, the person who discovered the element is given the honor of naming it. The name of an element is derived from its physical or chemical properties as well as its origin.

·        Elements' electronic configuration - An element's electron configuration describes how electrons are distributed in its atomic orbitals and their energy levels.

We discussed all types of NCERT exercise questions as well as intext questions in this NCERT Solutions Class 11.

In NCERT Solutions Class 11 we have to study various important topics such as:

·        Atom Structure - An atom is the smallest constituent particle of matter. A positive nucleus is surrounded by a cloud of negatively charged particles to form an atom. Positively charged particles make up the positive part of the atom. The proton and neutron are positively charged atom particles, while the electron is negatively charged.

·        Subatomic Particles Discovered - It was previously thought that an atom could not be further divided into smaller particles. However, in an experiment conducted by scientists in the nineteenth and early twentieth centuries, it was discovered that atoms are made up of smaller particles known as subatomic particles. An atom's three subatomic particles are:

o   Neutron – which has no charge

o   Electrons – which are negatively charged

o   Proton – which is positively charged

·        Atomic Models – after the discovery of the atom many scientists have proposed lots of atomic models throughout the history of modern physics. There are a total of 5 atomic models.

o   John Dalton's atomic model: Dalton´s Billiard Ball (Solid Sphere) Model.

o   J.J. Thomson's model: Plum Pudding model.

o   Ernest Rutherford's model: nuclear model.

o   Niels Bohr's model: Planetary model.

o   Erwin Schrödinger's model: Electron Cloud Model/Quantum Model.

·        Developments Leading to Bohr’s Model of Atom –

o   Niel Bohr describes the atom with the help of the concept of quantization.

o   Electrons revolve in an orbit and never lose their energy.

o   In an atom, the electron moves from a higher orbit to a lower orbit when it losses energy and if the electron moves from a lower orbit to a higher orbit it gains energy.

·        Bohr’s Model for Hydrogen Atom - Bohr’s prediction for smaller hydrogen atoms was correct, but it had its setback in describing the structure of larger atoms.

·        Quantum Mechanical Model of the Atom – the quantum mechanical model of an atom consists of ideas such as shells, sub-shells, and orbitals. It is also based on Schrodinger’s wave equation.

·        Motion in a straight line - A body is said to be in motion if its position changes with respect to time.

·        Types of Rectilinear or linear motion –

o   Uniform linear motion with constant velocity

o   Non-uniform linear motion with variable velocity.

·        Uniform Motion in a Straight Line - When an object in a straight line covers an equal distance in an equal interval of time, the object is said to be in uniform motion in a straight line.

·        Non-uniform Motion is a straight line - non-uniform motion occurs when a body travels an unequal interval distance in an unequal interval of time.

·        Path length refers to the total length traversed by an object.

·        Displacement is the shortest distance traveled by a body between its starting and ending points. It has an average speed.

·        The average speed of an object is the total distance traveled divided by the total time taken.

·        The velocity when the limit of the velocity is taken for an infinitesimal amount of time is referred to as instantaneous velocity.

·        Average acceleration is defined as the rate of change of velocity per unit of time.
