Elements that occupy the same column on the periodic table (called a "group") have identical valence electron configurations and consequently behave in a similar fashion chemically. For instance ...

Going down group 1, the melting point decreases. Lithium, Li Fizzes steadily; slowly becomes smaller until it disappears Sodium, Na Fizzes rapidly; melts to form a ball; quickly becomes smaller ...

The questions in this quiz are suitable for GCSE chemistry students studying the physical and chemical properties of group 0 elements (noble gases), group 1 elements (alkali metals) and group 7 ...

The periodic table of chemical elements, often called the periodic table, organizes all discovered chemical elements in rows (called periods) and columns (called groups) according to increasing atomic ...

There are repeating patterns in the properties of the elements, which give the periodic table its name. Elements with similar properties are arranged to form columns (groups). The periodic table ...

Even though chemists had identified relationships between small groups of elements ... Meyer and William Odling independently published their own versions of a periodic table. Meyer’s table was ...

The rows of the table are called periods, and the columns are called groups. Elements from the same column group of the periodic table show similar chemical characteristics. Trends run through the ...
