Hey there! Do you ever think about why mercury is still in liquid state at room temperature while other metals are solid at room temperature? It’s a bit of a puzzle, but let's put it into words in a simple way. To start with, a lot of metals such as iron, copper and gold melt at high temperatures, but mercury? It is cold around -38 degrees. 9°C (-38. 0°F). So, what’s the deal? Basically, it is the outer electrons' behavior that is the main factor in determining the shape of an atom. This illustrates that the electrons do not easily stick together thus weakening the bond between mercury atoms. So, even a small amount of energy can cause them to split, breaking mercury into a liquid. Now, picture this: Atoms bonding, some of their energy is stored in the bond and becomes unavailable. However, mercury has such a low energy in these bonds that even a small amount of movement can break them. And since heat is just an atomic level energy that is random, mercury doesn't need a lot...

It is time to switch over our organic solvents to green solvent. Recently EPA banned Dichloromethane solvent, after a long time  study on paint industries workers. EPA reported  88 deaths in their study. Conventional solvents are often involved in significant health and environmental risk,contributing to pollution, global warming, and resource depletion. To save our environment and life, the researchers have been actively trying to find green alternatives to traditional solvents. The green solvent has promising chemical characteristics with minimum hazardous impact during the use. What are Green Solvents? Green solvents are well known environmentally friendly or sustainable, having a low environmental impact. It is derived from renewable or easily available sources. They are made to reduce the use of dangerous materials and  minimize waste generation. During the use of this solvent, it promotes energy efficiency. Types of Green Solvents: Bio-based solvents: It is extract...

     How does the cornstarch jump when placed in a hot pan? Why? Because of the heat! Electron excitation is a process in which electrons gain energy and move from the ground state to a higher energy level. The excited atoms and nuclei return to the ground state, releasing this energy as visible light or gamma radiation that cannot be retained for long. Excitation is how a substance absorbs electromagnetic energy and is heated or ionised. Thanks to pixabay.com for image      Why is it important to understand electron excitation? Stimulated states of atoms, energy absorption, emission properties, optoelectronic applications, and chemical synthesis can be understood from it. Also in modern chemistry, the process of correlated electron-hole pairs and the kinetic Coulomb attraction. Which determines the energy apart from the energy of the orbit.  Secondary orbital relaxation and repulsion also play a role in electronic excitation processes. The methods of ...

Doesn't nature help us? Bacteria, viruses, or fungi spread in the air faster than humans and infect. But thank God! He has made such plants, which give protection against microbes. One of them is Neem tree!   The scientific name of neem is Azadirachta indica, commonly known as neem, margosa, nim tree or Indian lilac. It is native to parts of the Indian subcontinent and Southeast Asia, but is naturalized and grown in tropical and subtropical areas worldwide. Neem tree is known for its drought resistance. In India, the tree is known by various nicknames such as "sacred tree," "panacea," "nature's medicine shop," "village medicine" and "aksir cure for all diseases." In the southern states of Andhra Pradesh and Tamil Nadu in the Hindu tradition, the Amman festivals fall during the summer season. There is a good reason to celebrate festivals in the summer months (during the summer season) because certain heat-related diseases such...
