Chemistry is a branch of science that deals with the properties and physical and chemical characteristics of matter or matter and its interaction with energy. There are many differences that can be seen when comparing basic chemistry and modern chemistry. Basic chemistry comes from ancient times, namely in the days of scientists named alchemists. Importance […]

Philipine has some influential like Julian Banzon, Fransisco Santos, Alfredo Santos, Lourdes Jansuy Cruz, Dr. Jose Juliano, Amando Kapauan, etc. In this article we would like to discuss some list of Filipino chemists and their contributions. List of Filipino Chemists and Their Contributions There are some influential chemists in Philiphine and their contribution, as follows […]
Green chemistry has evolved from a small idea into a new approach to scientifically based environmental protection. By using green chemical procedures, Can minimize waste materials, keep the atomic economy and prevent the use of hazardous chemicals. Researchers and pharmaceutical companies should be encouraged to consider the principles of green chemistry when designing processes and […]
Chemistry is defined as a science that specifically studies material changes, either chemical changes, or physical changes. And can be studied through aspects of the process, properties and energy involved in material change. Indian chemists are more focused on the treatment system than looking for ways to make gold. Unlike China, Indian chemists do not […]
Tennant discovered iridium in 1803 in residuals remaining when raw platinum was dissolved with aqua regia. The naming of iridium is very feasible because the salts are brightly colored. Iridium, including platinum group families. It is white (same as platinum) but with a bit of pseudo-yellow. Because iridium is very hard and brittle, it is […]
Uranium is a chemical element in the periodic table that has the U symbol and atomic number 92. It is a silvery-white metal included in the actinide series of the periodic table. Uranium has 92 protons and 92 electrons, and has valence electrons 6. The uranium nucleus binds 141 to 146 neutrons, so there are […]
Radon is a chemical element in the periodic table that has the symbol Rn and atomic number 86. Radon is also included in the group of noble and radioactive gas. Radon is formed from radium decomposition. Radon is also the heaviest gas and harmful to health. Rn-222 has a half-life of 3.8 days and is […]
Rubidium (Rb), a chemical element of Group 1 (Ia) in the periodic table, an alkali metal group. Rubidium is the second most reactive and very soft metal sequence, with a silvery-white luster. Rubidium was invented (1861) spectroscopically by German scientists Robert Bunsen and Gustav Kirchhoff and named after two prominent red lines of its spectrum. […]
Barium is a chemical element in the periodic table that has the symbol Ba and atomic number 56. Barium is the fifth element in Group 2 and is a soft and silver alkaline earth metal. Barium is never found in nature as a free element because of its high chemical reactivity. Barium has a melting […]
What are harmful chemicals? Harmful chemicals are chemicals which are harmful to be use. But those harmful chemicals were still used until today in manufacture industry. Before we discuss it, we should have known the term of manufacture industry itself. (Read Harmful Chemicals in The Environment) Manufacture industry is industry that processes raw material into […]
