Not sure of the question, does the writer mean non-metals in the Periodic Table. The elements are grouped into three catrgories of metals, metalloids and non-metals.
The metals are situated in the left and middle portion of the table. The non-metals are located at the top right corner, and the metalloids lie between the metals and non-metals.
If not sure here here are the metalloids - from the top, we have Boron (B), Silicon (Si), Germanium (Ge) and Arsenic (As), Antimony (Sb) and Tellurium (Te), and finally Astatine (At).
Hope this helps
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

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.

There is a group of elements in the periodic table as the elements with same properties are clubbed together.
