Variation in Properties of Group II Compounds
... The oxides of group II elements react readily with water to form alkaline solutions. The reactivity of oxides towards water increases down the group. For example, BeO has a high degree of covalent characters, is inert and almost insoluble in water and acid; MgO is almost inert towards water but diss ...

... • Based on similarities in their chemical properties, elements on the periodic table are arranged in columns, which are called groups. • An atom’s chemical properties are largely determined by the number of the outermost electrons in an atom’s electron cloud. These electrons are called valence elect ...

SOME BASIC CHEMICAL TERMS
... Most of the materials we encounter in our daily lives, such as air, milk, and steel, are mixtures. Mixtures contain two or more substances that can be physically separated from each other. Some mixtures, such as sand mixed with gravel, are heterogeneous, in other words, we would have no trouble dist ...
