The atom is the most crucial part of a chemical element, breaking which we find protons, electrons, and neutrons. They all play a key member in the formation of chemical bonds.Many scientists have incredibly contributed to different specialties of chemistry. One of them was American chemist, Gilbert N. Lewis who introduced the concept of electron dot structure in 1916.The article the atom and the molecule tell about the position of valence shell electrons in a chemical bond....

It occurs as a diatomic gas and is also the third most abundant element in the universe. It is a colorless and odorless gas with oxidizing properties. Oxygen is required for several processes such as combustion, cellular respiration, etc.It also forms a part of many important organic molecules such as proteins, carbohydrates, nucleic acids, etc. Plants breathe out oxygen in the environment thus, replenishing it.Hey guys!!! Our topic for today is the Bohr model of oxygen....

To us, air appears as a colorless mixture. So, let us learn more about air and mixtures.So is air a homogeneous mixture? Yes, the air is a homogeneous mixture. Air is composed of several gases, but it appears uniform everywhere and its components cannot be distinguished from each other easily. Also, different components of air cannot be separated using simple, mechanical methods. This is why air is classified as a homogeneous mixture....

Let us dive in to know some interesting facts about Graphene and Diamond.So, the answer to whether Graphene is stronger than a diamond is yes; Graphene is stronger than diamond. Graphene is a single plate of carbon atoms. It is about forty times stronger than a diamond....

Many students doubt if saltwater is a compound. In this blog, let me clear all your doubts and explain to you what exactly is saltwater.So, is saltwater a compound? No, salt water is not a compound, rather it is a homogeneous mixture of Sodium Chloride ions and water. To be more precise, we can call it to be a solution. When salt is added to water and mixed, no new compound is formed....

Naturally, this leads many people to ponder the pH of watermelon, whether it is acidic or alkaline.Watermelons are one of the lowest-acidic foods that have a pH range of 5 to 6 and 9 when they are fully ripe. Because they contain about 90% water in their bodies, they have an alkaline-forming effect on their solution as they ripen. Watermelons are considered to calm our hearts and hydrate our bodies, among many other health benefits....

Beryllium was discovered by Nicolas-Louis Vauquelin. It is steel grayish in appearance and is brittle at room temperature. It is the lightest member of alkaline earth metals and is used as a hardening agent in metallurgy. It is distributed in the earth’s crust and is found in igneous rocks.Hello friends! We are here again with another interesting element to help you with its Bohr model.In this article, we will talk about Beryllium....

This gas has an unstable molecular structure which is prone to violent rupturing if exposed to heat for a longer period. The unstable behavior of carbonyl fluoride is not only dedicated to heat but to water as well. In the presence of water, carbonyl fluoride hydrolyses hydrogen fluoride and carbon dioxide.Moreover, the carbonyl fluoride is prepared as a byproduct of the decomposition of fluorinated hydrocarbons, like tetrafluoromethane or trifluoromethanol during the thermal decomposition....

When we talk about the properties of rubber, one of the most common questions is whether rubber conducts electricity or not. Most people have an idea that metals conduct electricity while insulators such as plastic and wood do not. The reality is more than meets the eye.So, does rubber conduct electricity? No, rubber does not conduct electricity. Its lengthy chain-like polymer structure prevents the electrons from moving freely. This is due to the strong bonding of electrons in its valence shell that limits the transfer of electric current....

So, Is Br2 Polar or Nonpolar? Br2 (Bromine) is nonpolar because, in this molecule, both bromine atoms have the same electronegativity due to which both atoms have equal charge distribution and results in a net-zero dipole moment. It is linear in structure.At room temperature, Bromine exists in a liquid state with reddish-brown texture. It is volatile in nature, readily evaporates in the form of a gas.It is classified as a halogen compound....

So, Is CBr4 Polar or Nonpolar? CBr4 (Carbon tetrabromide) is nonpolar in nature because of the symmetrical arrangement of four bromine atoms around carbon. As a result, the dipoles of the C-Br bond get canceled by each other resulting in CBr4 a nonpolar molecule.If we talk about the chemical composition of carbon tetrabromide, there are four bromine atoms and single carbon atoms attached via covalent bonds with each other.The bond energy of the C-Br bond is around 235 kJ....

So, is mercury magnetic? Yes, under the influence of an external magnetic field, mercury magnetizes and strongly repels the magnet. It is due to the presence of paired electrons that undergoes a cage diffusion phenomenon to generate a magnetic moment.Mercury is a liquid metal that is often sought to be non-magnetic in nature.It is because, at room temperature, mercury never attracts a magnet. Magnetism is a force that is modulated by magnetic fields of elementary particles What is cage diffusion?...

These brown coffee beans are available in the market and are brewed into our cup of coffee. Brewing is supposed to extract the soluble flavored compounds from the coffee beans into water.There are many species of coffee, but the most useful ones are Coffea arabica L. and Coffea canephora Pierre. The flavor of coffee, which is prepared using Coffea arabica beans, is mild, and this coffee has a better aroma and quality....

In this article, I will attempt to answer all these questions and more!So, why is the ozone layer important? The ozone layer protects living beings from harmful ultraviolet radiations that cause severe harmful effects including skin problems, risk of DNA, and other cellular damage. The Ozone (O3) layer is a part of the Stratosphere. It is present in traces in the atmosphere but is good in trapping UV radiations (specifically UVB radiation) and absorbs around 95% of UV-B rays and prevents it from reaching the Earth’s surface....

In this article, we will understand the concepts of prediction of Lewis structure, geometry, hybridization, and polarity of a given compound. Lewis Structure Lewis Structure is a 2-D representation that depicts the arrangement of atoms and valence shell electrons on those atoms in a compound.Many attempts were made to explain the formation of the chemical bond. Lewis was among the first ones to explain. He postulated that only valence electrons take part in bonding, and hence in his representation, only valence electrons are considered....

Some people call these clouds fog. But not all dense white air is fog. It can also be mist. Like many people, you may also not know the difference between fog vs. mist. Although both fog and mist are formed by water condensation because of a sudden drop in temperature, there are some differences between these two. They do not have the same density, and the locations they form in also vary....

So, Is HBr Polar or Nonpolar? HBr (Hydrogen Bromide) is a polar molecule because of the unequal electronegativities of Hydrogen and Bromine atoms. Bromine has a higher electronegativity than hydrogen due to which electron bonded pair gets attracted slightly more towards bromine atom making HBr a polar molecule and results in a net dipole moment.HBr is readily soluble in water. It is an acid mixed with water. At room temperature, Hydrogen bromide present in water gets saturated at 68....

So, is lead magnetic? Lead is diamagnetic in nature. The sole reason behind this is the alignment of atomic spins in the reverse direction to that of applied magnetic fields. Basically lead is a paramagnetic atom with 2 unpaired electrons (electronic configuration is [Xe] 4f14 sd10 6s2 6p2 ), but “lead metal” is diamagnetic because the unpaired electrons pair up in bonding MOs. Another reason is that the magnetic susceptibility of this diamagnetic metal is -1....
