An atom is the smallest particle of an element that can exist and still retain the properties of that element. Atoms are made up of protons, neutrons, and electrons, and they are the building blocks of all matter. Atoms are held together by chemical bonds, which allow them to form molecules and other compounds. Atom …
Symbols of elements are used to denote the chemical element and are usually one or two letters from the Latin alphabet. They are used to easily identify and distinguish elements from one another and can be used to indicate the number of protons and electrons in an element’s atomic structure. By knowing the symbol of …
Polonium was named after the country of Poland. The element curium was named after Marie and Pierre Curie, two scientists who discovered radium and polonium. Chromium is the element with atomic number 24 and symbol Cr. It was discovered in 1797 and was the first element to be named after a color, in this case …

In chemistry, elements are the simplest forms of matter, consisting of one type of atom. There are 118 elements found in nature, divided into metals, nonmetals, and metalloids. Examples of elements include hydrogen, oxygen, carbon, and iron. The pure substance which cannot be further decomposed through chemical process is called elements. Compounds in chemistry are …

Sir Humphry Davy’s experiment to divide water involved the use of electricity. He used a battery to pass an electric current through a container of water. This caused the water to break down into its constituent elements of hydrogen and oxygen. The two gases rose to the top of the container and were collected separately.Henry …
Fill the quarter boiling tube with sugar and close it with cotton .Then heat the boiling tube strongly. What can be observed ? When the boiling tube is heated strongly, the sugar will begin to melt and caramelize. As it caramelizes, it will become darker in color and produce a sweet, smoky smell. The end …

Materials are the substances used to make things. There are numerous peculiarities that can be associated with materials. One of the most common peculiarities is the material’s physical properties, such as strength, flexibility, durability, thermal conductivity, and electrical conductivity. These properties can affect the performance of a material in a particular situation. Additionally, materials can …

Chromatography is a method of separating mixtures of substances into their individual components. It is used in a wide range of applications, such as analyzing the components of a drug or to separate and identify different proteins in a sample. Chromatography works by passing a mixture of components through a stationary phase, such as a …
Centrifugation is a process used to separate components of a liquid mixture by spinning it in a centrifuge. The centrifugal force generated by the spinning causes the heavier components of the mixture to settle to the bottom of the container, while the lighter components remain suspended in the liquid. Centrifugationis often used in laboratories to …
Sublimation is the process of a substance transitioning directly from a solid to a gas without passing through the liquid phase. Separation is the process of separating two or more substances from a mixture. Separation can be used to separate the components of a mixture as part of the sublimation process. For example, a solid …
