An element, simply put, is afundamental unit of matter that cannot be easily broken down. It consists of a specific number of protons and variable neutrons and electrons. All of matter is made of these 118 elements, combined in various ratios and kept in different states, like solids. Depen...
, silver, gold, mercury, tin, lead, and other elements have been known since ancient times and were used to make jewelry, coins, and tools. Phosphorus became the first element to be discovered by Hennig Brand in 1649. It is known as the first scientific discovery of a chemical element....
Each element page in this book contains terms that might not be completely familiar. Refer to the definitions in the back of the book to get a clear understanding of each meaning. There is also a fun unicorn themed Periodic Table at the back of the book. ...
What is atomic number? The atomic number of an element is equal to the total number of protons in the nucleus of the atoms of that element. The atomic number can provide insight into the electronic configuration of the element. For example, carbon has an electron configuration of [He] 2s22...
