The Patterns Seen in Physical Properties and Reactivity in Groups - Assignment Example

Fluorine, for instance, is so electro-negative and hence can displace oxygen from water to form oxygen gas and Hydrogen fluoride. Generally, halogens react with water to form hydrohalic or hypohalous acid. All the elements in this group have one electron in their outer electron shell. These elements have a very high tendency to lose the electron in the outermost shell. When they lose this electron they become positively charged ions with the stable electronic configuration of their neighboring Noble gases.

The elements in this group are; It is composed of elements that have a full outer shell and therefore have no tendency whatsoever to gain, lose or share electrons. They are majorly inert elements. By having a low tendency to gain, lose or share electrons since they have a full outer shell, they are unreactive. Owing to their monatomic nature, therefore, they are inert. All the elements in this group have one electron in their outer electron shell. These elements have a very high tendency to lose the electron in the outermost shell.

When they lose this electron they become positively charged ions with the stable electronic configuration of its neighboring Noble gases. . The reactivity of these elements increases down the group i.e. cesium is the most reactive of the group. By having a high tendency to gain or share an electron, group seven elements are very reactive. They react violently with group one’s elements to form salts. Reactivity generally decreases down the group from fluorine being the most reactive and bromine being the least reactive of the group.
