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 :)
is the table of this period is the thing that has no value for every thing
Oxygen and sulfur are non-metals. Selenium, tellurium and polonium are semi-metals. Livermorium might be more metallic, but has such a short half life that its chemistry is of no importance.
Oxygen.
Yes.
the most reactive (non-metals) group in the periodic table is GROUP 17+they are all reactive
Group 'III'
Upper right hand corner. As far as possible from the border between metals and non-metals.
The right side of the periodic table consists of non metals. It contains non metals such as carbon, and gases such as the noble gases.
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)"
the most reactive (non-metals) group in the periodic table is GROUP 17+they are all reactive
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
Group 'III'
Non metals are located on right side in Periodic Table. They are present in group-15,16,17.
Upper right hand corner. As far as possible from the border between metals and non-metals.
Group-17 are most reactive non-metals. They form halogens.
The right side of the periodic table consists of non metals. It contains non metals such as carbon, and gases such as the noble gases.
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.
Hydrogen is a non-metal; it's in group VII
