Senyawa
Senyawa, in Indonesian, translates to "compound" in English. In the context of science, particularly chemistry, it refers to a substance composed of two or more different elements chemically bonded together. These elements are combined in a fixed ratio by mass. The chemical bonds between the elements can be covalent bonds (sharing of electrons) or ionic bonds (transfer of electrons). A compound has distinct chemical properties different from those of its constituent elements. Examples of senyawa include air (a compound of oxygen and nitrogen), water (H₂O), and table salt (sodium chloride - NaCl). The properties of a senyawa are determined by the types of elements present and the way these elements are bonded together.
