Another surprising example of chemistry is a soap that is being used by people for quite a long time now. Crude soap is made by humans by mixing animal fats, ashes, oil-based grease, and cleaner. It's quite amazing how something that messy dirty makes us clean. The answer lies in the...
An atom consists of a fixed number of protons, electrons and neutrons, which makes each element unique. Protons and neutrons together make up thenucleus of an atomwhile the electrons orbit around it. In the periodic table, a chemical element is represented by a fixed format : Atomic number= ...

What is the Periodic Table of The Elements?"It is a huge, efficient resource!"The periodic table is the most important chemistry reference there is. It arranges all the known elements in an informative array. Elements are arranged left to right and top to bottom in order of increasing atomic...

Someone who is intrigued by the way atoms combine into molecules or who is fascinated by the diversity of elements on the periodic table may want to pursue a degree in chemistry. What Is Chemistry? This field of science offers insight into the ingredients necessary to form various substances ra...
Some chemistry examples in everyday life include the burning of gasoline (a chemical reaction), sunscreen (chemical that reflect harmful ultraviolet light), and even breathing (the extraction of oxygen gas from the air). What is chemistry in simple words? Chemistry is the study of the substances...
Chemistry is a physical science, which means it doesn't involve "living" things. One way a lot of people practice chemistry regularly, perhaps without realizing it, is in cooking and baking.(Image credit: Shutterstock) The five main branches of chemistry ...
Oxygengenerally*has a mass number of16(seePeriodic Tablesonline or in chemistry textbooks), but another isotope of oxygen isoxygen-18, which includes an extra 2 neutrons. Phosphorusgenerally*has a mass number of31(seePeriodic Tablesonline or in chemistry textbooks), but another isotope of phosphor...
The periodic table is a tabular arrangement of the chemical elements by increasingatomic number, which displays the elements so that one may see trends in their properties. The Russian scientistDmitri Mendeleevis most often credited with inventing the periodic table in 1869. The modern table is der...
