The groups I to V you are referring to are likely the first five groups of the periodic table. These groups contain a variety of cations with different properties and reactivities. Group I cations include silver (Ag+), which is often used in jewelry and silverware, and mercury (Hg2+), which is a toxic heavy metal. Both…
Group 15 of the periodic table is known as the Nitrogen Group or Pnictogens. It includes the elements nitrogen (N), phosphorus (P), arsenic (As), antimony (Sb), bismuth (Bi), and moscovium (Mc). Oxygen (O) is not a part of this group, it belongs to Group 16 or the Chalcogens. The elements in Group 16 are oxygen…
Group 14 elements include carbon, silicon, germanium, tin, and lead. Among these, carbon has the most well-known and diverse allotropes. Allotropes of carbon refer to different forms of carbon that have different physical and chemical properties. Here are some of the most important allotropes of carbon: Uses of carbon: Carbon has a wide range of…
Borax, also known as sodium borate, is a versatile substance with a wide range of uses. Here are some of the uses of borax: History of Group 13 Uses of borax Borax has been used for various purposes for thousands of years, and its history can be traced back to ancient civilizations. Here are some…
Group 13 of the periodic table contains three elements, all of which are metals: boron (B), aluminum (Al), and gallium (Ga). These elements are not halogens. The halogens are found in Group 17 of the periodic table and include fluorine (F), chlorine (Cl), bromine (Br), iodine (I), and astatine (At). These elements are non-metals and…
The law of partial pressures, also known as Dalton’s law, states that the total pressure of a mixture of gases is equal to the sum of the partial pressures of the individual gases in the mixture. In other words, if you have a gas mixture made up of two or more gases, the total pressure…
Conditional probability is the probability of an event occurring given that another event has already occurred. It is denoted by P(A|B) and read as “the probability of A given B”. The formula for conditional probability is: P(A|B) = P(A and B) / P(B) Where P(A and B) is the probability of A and B occurring…
Thermal Physics is an important topic in the JEE (Main+Advanced) exam, and it requires a strong understanding of fundamental concepts and their applications. Here is a brief overview of the key topics you should focus on: In addition to these topics, it is also important to practice solving numerical problems and to become familiar with…
The JEE (Main+Advance) repeater course is designed for students who have already attempted the JEE examination but did not score well enough to secure a seat in their preferred engineering colleges. The repeater course is focused on providing these students with an opportunity to improve their performance and achieve a better rank in the JEE…
JEE (Joint Entrance Examination) is a national-level engineering entrance exam in India that is conducted for admission to undergraduate engineering courses in Indian Institutes of Technology (IITs), National Institutes of Technology (NITs), and other centrally-funded technical institutions. A repeater course in JEE (Main+Advanced) is designed for students who have already attempted the exam at least…
