What are the trends of Group 7 elements?
The halogens are five non-metallic elements found in group 7 of the periodic table. The term "halogen" means "salt-former" and compounds containing halogens are called "salts". All halogens have 7 electrons in their outer shells, giving them an oxidation number of -1. The halogens exist, at room temperature, in all three states of matter:

The elements are arranged in rows in order of increasing atomic number (nuclear charge). Each vertical column, called a "group" or "family" of elements, contains elements that have rather similar physical properties and chemical behavior. Within a group, however, there is often a steady variation in the properties from top to bottom of the group.

In the case of silicon and all other group IV elements except carbon, hydrolysis of the tetrachloride is accomplished by attack of the water molecule to the electron-deficient metal atom. The group IV metal atom can use a vacant low lying 3d orbital to accommodate the lone pair from the oxygen atom, forming a .
