In the table below you will find three descriptions of scientists engaging in activities that are part of the scientific method. What are the missing words? description Wolfgang develops a about the arrangement of elements in the Periodic Table, based on some ideas about how electrons are arranged in the different atoms of different elements. Using equations he develops, he is able to predict the exact arrangement of electrons in many atoms, and from there predict why they are where they are in the Periodic Table. After studying the chemical reactions of many compounds made of carbon, August discovers a that says carbon always forms 4 chemical bonds to other atoms when it forms a compound. Antoine burns some charcoal, and a very small diamond (!), and makes the that the only product of both reactions is a heavy gas (carbon dioxide). missing word? 1 0 Ś
Electron Affinity
When an element undergoes a chemical reaction, it either gains energy or loses energy. This gain or loss of energy is due to the phenomena that occur at atomic level. During reaction, atoms either gain electrons from other atoms or lose electrons to other atoms, and in that process, energy is produced.
P-Block Elements
Elements which are present on the right side of the periodic table are called p-block elements. In addition to the noble gases, they include the families of boron, mercury, nitrogen, oxygen and fluorine. These elements have diverse real-life implementations that we regularly experience around us.
Metals and Non-metals
The periodic table is composed of metals, semi-metals and nonmetal elements. The physical and chemical properties of metals and nonmetals differ from each other. The study of metals and nonmetals will help one to understand the appropriate application of the particular element.
