Web23 mrt. 2024 · The elements lying in the same groups show similar chemical properties and they also have same number of valence electrons. For example; Example of group 1 All the elements of group 1 are highly reactive to water. They are soft and can be cut easily with a kitchen knife. Also all the elements of group 1 have one valence electron. In chemistry and atomic physics, the main group is the group of elements (sometimes called the representative elements) whose lightest members are represented by helium, lithium, beryllium, boron, carbon, nitrogen, oxygen, and fluorine as arranged in the periodic table of the elements. The main group includes the elements (except hydrogen, which is sometimes not included) in … WebIt is fair to say that main group elements are not the most glamorous members of the periodic table. The s-block metals such as calcium, and p-block elements like boron and germanium, are literally outshone by their flashier transition metal neighbours gold, palladium and rhodium. palais a vendre italie
