alka_han is a chemical educational game for matching elements through their groups. This application is expected to make someone who plays this game will be better able to match elements into compounds by knowing the element groups that are owned. When someone knows the class of an element, he will more easily know the properties of elements such as ionization energy, boiling point, melting point and so on. With knowledge of the nature of the elements of someone who plays this game is also expected to be able to make compounds with predetermined criteria for example in the manufacture of ion compounds, one must match the elements that release electrons with elements that capture electrons. Unlike the case when making covalent compounds where one has to match compounds that release electrons with those who release electrons as well. Vice versa with the capture of electrons must match the capture of electrons as well. This game is expected to help learning about the chapter of the periodic system of elements and the nature of the elements.
