Complete Explanation of CBSE Notes
Reproduction is a very important biological process for all organisms in the continuity of the generations. There are different types of living species existing on this planet earth. Few are a single-celled organism, some are multicellular organism while few species lack a true nucleus and other cell organelles. Reproduction varies with the species. please refer How do Organisms Reproduce Class 10 Notes for more revision notes.
Both plants, animals and other living organisms respond to changes in the environment in a different manner. These detectable changes are called the stimuli, which include light, cold, heat, smell, sound, touch, etc. Please refer Control and Coordination Class 10 Notes for more revision notes.
What is Life Process?
The basic essential activities performed by an organism to sustain life on earth is called as Life Process. There are seven important life processes which are common to all plants, birds, and animals, which includes: Growth, Movement, Respiration, Transportation, Excretion, Reproduction, and Nutrition.

What is Periodic Classification of Elements?
The tabular arrangement of the chemical elements, ordered according to their atomic number, electron configuration, recurring chemical properties is termed as the Periodic Classification of Elements Class 10 Notes.
Dmitri Ivanovich Mendeléev, a Russian chemist, was a success in arranging the elements. Hence it is referred to as the Mendeléev’s Periodic Table.
Carbon is one of the most important and useful elements in the world. Air is a mixture of gasses which includes 0.0391 percent of carbon. It is the raw material for photosynthesis and is used in form of charcoal, graphite, etc. Carbon is found all around us. Food, fossil fuels, drugs, air, are all either a compound of carbon or its substituents. The Atomic number of carbon is 6, its Weight is 12 and is represented by its symbol C. Please refer Carbon and its Compounds Class 10 Notes for more revision notes.
Elements are broadly classified into metals and non-metals. In the modern periodic table of elements, Metals and Non-metals Class 10 Notes are grouped separately. All metals are arranged on the left side and the nonmetals on the right side. Altogether there are 70 metals and 22 non-metals in a periodic table of elements.
What are Metals?
Metals are lustrous, opaque, ductile and malleable, and good conductors of heat and electricity. Most of the metals are solids at room temperature, except few. There are many metals that occur in nature either as free elements or in the form of their compounds. Aluminum, Copper, Iron, Zinc, are examples of metals.
What are Nonmetals?
The elements, which do not possess the properties of metals are termed as non-metals. hydrogen, carbon, nitrogen, phosphorus are examples of non-metals. They are brittle and can be easily broken into sub-particles. They are bad conductors of heat and electricity and exists in both solids and gases except few.
Acids, bases, and salts are three main groups of chemical compounds. They have certain definite properties which can distinguish from each other.
An Acid can be defined as a compound which produces hydrogen ion (H+), when it is dissolved in water. The word acid is derived from the Latin word meaning sour. Acids are found in many substances including the fruits. For example, citric acid is present in citrus fruits.
Bases can be defined as a compound which produces hydroxide ion (OH-), when dissolved in water. They are found in all soaps, toothpaste, egg whites, dishwashing liquids, and ammonia.
Salts can be defined as a compound formed by the combination of acids and bases through the neutralization reaction. The common examples of salt are sodium chloride or table salt, Magnesium sulphate used as bath salts, Ammonium nitrate used as fertilizers, and baking soda used in cooking.

What is Chemical Equation?
A chemical equation is the symbolic representation of a chemical reaction which is represented in the form of symbols and formulae. The main features of a chemical equation is as follows:

Class 10 is a crucial point for students in their education journey. Besides, the marks scored in the board exam, class 10 will also help students to choose the desired stream for their higher studies and also frames the better career. So it is important for every student to study effectively and score good marks in their CBSE class 10 board exam.
In order to help students to develop a proper study methodology and succeed in their exams, we are providing chapter wise notes for the complete syllabus provided in their CBSE Class 10 Science Notes . These notes are available in the pdf format and students can either download or practice through online.
The CBSE class 10 Science notes have been prepared by experienced subject experts, which includes in detailed explanations along with illustrative examples, solved questions, as well the sample questions papers to help students to prepare well for their board exam.
The Probability Class 10 Notes: Chapter 15 is provided here, which highlights all the important concepts, formulas, and laws that are included in this chapter. The class 10 probability concepts that are covered in these notes are:
