The periodic table arranges all of the known elements in order of increasing atomic number. Element groups are either nonmetals or various subsets of metals, but there is no distinct line between the two types of elements. Alkaline earth metals: The alkaline earth metals make up. Elements in the same group of the periodic table show trends in physical properties, such as boiling point. They have the same number of electrons in their outer. There are multiple ways of grouping the elements, but they are The basic metals are similar to transition metals but tend to be softer and to.
Remember that Mendeleev arranged the periodic table so that elements with the most similar properties were placed in the same group. It's mainly due to the number of electrons in their valence shell. The alkali metals each only have one valence electron, thus they are the most reactive elements. Two different elements have similar chemical properties when they have the same number.
The elements of a group have similar chemical properties but in a period they have different chemical properties. This is because the chemicals. The alkali metals make up group 1 of the Table, and comprise Li through Fr. They have very similar behavior and characteristics. Hydrogen is group 1 but. All Group 11 elements are relatively inert, corrosion-resistant metals. Copper and gold are colored. These elements have low.
