I'm pretty sure its Tellurium (Te)! I didn't get it at first as well, but i searched it up and thats what i got :)
The halogens (Group 17) are the most reactive non-metals in the periodic table. They have seven valence electrons and readily gain an electron to achieve a full outer shell, resulting in high reactivity. This group includes elements such as fluorine, chlorine, bromine, and iodine.
The metalloids split the table these are a diagonal group of elements, B, Si, Ge, As, Sb and Te. To their right are the non metals to the left the metals. There are many more metals than any other type of element. See Wikipedia article "Periodic table (metals and non metals)"
All the element in group 1 are metals except for hydrogen which if you notice, is not exactly in group 1. It is situated away from the periodic table because it can react as a metal as well as a non metal. Hope this helped...
No, all elements on the periodic table cannot be classified as metals or non-metals. The periodic table includes metals, non-metals, and metalloids, which have properties of both metals and non-metals. Elements are classified based on their physical and chemical properties, such as conductivity, reactivity, and appearance.
Most elements on the periodic table are classified as metals, with only a few elements classified as non-metals.
Group 18 of the Periodic Table has only non metals. Additionally, the stable elements of group 17 are also non metals.
Divides metals and non metals
Non metals are located on right side in Periodic Table. They are present in group-15,16,17.
Group-17 are most reactive non-metals. They form halogens.
Hydrogen is a non-metal; it's in group VII
its the boron group which contains one metalloid and 5 metals

salts
Non-metals and metalloids are found to the right on the periodic table.
The periodic table comprises of metals (on the left) ,non-metals(on the right ) and transition elements (between metals and non-metals) in the periodic table.
Group 17 - the Halogens
Group 1 (metals) and Group 17 (non-metals).
