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...

NA(a) What is a group in the periodic table in which part of a group would you separately expect elements to have (i) the greatest metallic character (ii) the largest atomic size? (b) In what respects do the properties of group 1 elements differ from
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...
A chemistry degree may lead to a job in a variety of industries, including health care, forensics and pharmaceuticals. 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 chemi...
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...
Platinum is a naturally occurring chemical element that is actually about 30 times rarer than gold, according to Jenny Luker, president of Platinum Guild International USA (PGI), a marketing organization for the platinum jewelry industry.
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...
Chemistry is a science that tries to understand the properties of substances and the changes that substances undergo. It is concerned with the substances that occur in nature-the minerals of the earth,the gases of the air,the water and salts of the seas,the chemicals of the living creatures,...
