What happens to the resistance of most common metals as the temperature of the metal increases? The fluid property due to which mercury does no wet the glass is? A certain element has its outermost electron in a 2s subshell. It has valence +1 because it has 1 more electrons than a certa...
At the other end of the spectrum, the electrical and mechanical carbon and graphite products cartel instituted a sophisticated pricing rule which, in principle, allowed for many different prices depending on the particular characteristics of the product and the buyer. One ...
Which of the following materials is the poorest electrical conductor? (A) Copper (B) Aluminum (C) Graphite (D) Brass Explain the difference between an insulator, a conductor, and a semiconductor. Give an example of each to illustrate your comparison. ...
An LFP battery gets its name from it’s key material component, lithium iron phosphate powder, which has the chemical formula LiFePO4. It is also known as lithium ferro phosphate which gets shortened to LFP, hence the name. Learn more... ...
The salt that we add to our food is the mineral halite. Antacid tablets are made from the mineral calcite. Rubies and sapphires are colored varieties of a mineral named corundum. It takes many minerals to make something as simple as a wooden pencil. The "lead" is made from graphite and ...
Permittivity (electric permittivity) is the ratio of electric displacement to the electric field intensity. It is a constant of proportionality between these two parameters. In the meter-kilogram-second and International System of Units (SI) frameworks, thepermittivity of free spacein a vacuum is sy...
Carbon is a non-metal and therefore has covalent bonds. However, in this experiment, it exhibited metallic properties. Carbon in the form of graphite is the only non-metallic element that conducts electricity. As we all know,graphiteis composed of sheets of hexagons of carbon atoms joined by...
Hexagonal boron nitride (hBN), often known as 'white graphite', is a high-performance ceramic material used across a wide range of industrial applications. Its structure resembles that of graphite, yet its behavior is strikingly different, especially when exposed to high temperatures or electrical ...
Electronegativity of An Element: Electronegativity of an atom is a measure of the tendency of an atom to attract the shared electron cloud towards itself in a covalent bond. It depends upon the nuclear charge and the atomic size. The higher the electronegativity, the higher is the tendency of...
The polymorphism of silicon dioxide results in different types of quartz. 8 Amorphism Lack of crystalline structure Glass is a classic example of amorphism. 15 Polymorphism Existence in different forms Carbon's polymorphism is evident in diamond and graphite. 4 Amorphism Random atomic arrangement A...
