NOMENCLATURE OF ELEMENTS

15.5.20
DAY 5

Good Morning  Boys,
Today we will learn the rules for naming elements with atomic number greater than 100.

Learning Outcome:
student will be able to

  • Learn the rule
  • Apply Rule to element with Atomic number greater than 100
1.A systematic Nomenclature is derived directly from the atomic number of the elements using the numerical roots for 0 to 9.
2.The Root word are put together inorder of digits which make up the atomic number.
3. ium is added as a suffix.
The Table Below will enchance your learning on nomenclature of elements of a given atomic number.




THATS ALL FOR THE DAY
MARK YOUR ATTENDANCE ON THE FORM

Chemistry Practical 11 D

Day 4 18.4.20 Good Morning students:  Today is our first chemistry practical period through blogs. please read the general instruction carefully. General Instructions :  1. students must get the concern slip signed by the parents for working in the laboratory. The concern slip contains the guidelines for working in the laboratary. Written guidelines for working in chemistry lab would be given once the school reopen. kindly note signature of  parent on concern slip is mandatory for working in chemistry lab. 2. Labcoat is mandatory for working in the lab. 3. carry your practical file and stationary during the practical period. 4. Follow the Instruction given by teacher at all times. 5. Casual attitude while working in lab will not be entertained. 6. Class would be divided into 2 batches: Batch 1 Physics Batch 2 chemistry (depending on the strength of class ) At present both the batches would be writing the practical in your chemistry file. The p...

Definations and molecular mass calculation

Day 1         4th period 21. 4.20 FOR MARKING YOUR ATTENDANCE TYPE YOUR NAME AS PER THE DIRECTIVES GIVEN BELOW ⇓ AND CLICK SUBMIT. Loading… GOOD MORNING BOYS, Today we will be going through the various definations and calculate the molecular masses of compound. Learning objective : students will be able to Define atomic mass, Molecular Mass & formula mass calculate molecular masses of compounds. Atomic mass unit   It is defined as a mass exactly equal to one twelfth the mass of one carbon – 12 atom. Gram atomic mass of a substance  –   The atomic mass of a substance when expressed in grams is known as its gram atomic mass. The atomic mass of Sulphur is 32u. Gram atomic mass of Sulphur is 32g .   Molecular mass It is the sum of atomic masses of the elements present in a molecule.  It is obtained by multiplying the atomic mass of each element by the number of its atoms and  adding them ...
DAY 3 30.4.20 GOOD MORNING BOYS, Today you will attend the MCQ FIRST then you will  learn about Hydrogen spectrum and Bohrs theory. Loading… LEARNING OUTCOMES: Students will be able to know different series in hydrogen spectrum learn Rydbergs formula understand Bohrs model for hydrogen atom. Emission spectrum of Hydrogen atom Spectral Lines for atomic hydrogen is given by Rydberg equation R = Rydberg’s constant = 109677 cm -1 B ohr’s model for hydrogen atom: Postulates  1. Electron in hydrogen atom moves around the nucleus in circular path of fixed radius and energy. These paths are called orbits or energy levels. 2. As long as an electron remains in a particular orbit, it does not lose or gain energy and its energy remains constant. 3. However, when electron will move from a lower stationary state to a higher stationary state a certain amount of energy is absorbed by the electron or some energy is emitted when electron moves fr...
