the groups of alkali metals, alkaline earth metals, transition metals, and other metal are all metals and some of the metalloids have metallic properties and the alkali, alkaline are on the left, transition metals are in the middle, other metals are located directly next to the transition metals and the metalloids are next to the other metals, and then you have halogens and Nobel gases, Lanthanides and Actinides which are all gases and rare earth.
Non-metallic properties
metallic elements are found in the center of the periodic table, and nonmetallic elements are anywhere but the middle...
Apart from hydrogen, they are very reactive metallic (alkali) elements.
The elements with similar properties are placed in groups. Periodic table contain 18 groups.
They have simliar properties and same elements although later on more elements were added to the modern periodic table.=Both periodic tables have elements grouped by similar properties. Mendeleev's periodic table had elements arranged in order of increasing atomic mass in columns with similar properties. While many of the elements are in order of atomic mass on the modern periodic table, some are not, as the modern table has elements arranged in order of increasing atomic number.=
across a periodic table, the properties of elements become less metallic and more nonmetallic
Non-metallic properties

Elements in group A are metals. They possess metallic behaviour.
Elements in group A are metals. They possess metallic behaviour.
Elements in group A are metals. They possess metallic behaviour.
The Periodic Table of the Elements, sometimes called just the Periodic Table, is the document in which elements are organized by their properties. It was created in 1869.
The number of electrons to be gained or lost is what differientiates metallic and non-metallic elements on the periodic table at a subatomic level.
Apart from hydrogen, they are very reactive metallic (alkali) elements.
iron
There is a group of elements in the periodic table as the elements with same properties are clubbed together.
