noble halogens
Element 118 is a noble gas, which means it would be largely unreactive. Only a few atoms of this gas have been synthesized.
Because they both have a different number of valence electrons in their outer shells, and that is what determines the properties of the element.
Knowing the nuclear charge of an element is important as it will tell you what kind of reactions you can expect. The element with the nuclear charge of 25 is manganese.
The newest officially discovered elements are Ununquadiumand Ununhexium so, we'll focus on those.Ununquadium will be part of the Carbon series, so we would expect it to have properties similar to those elements (e.g. 4 electrons in the outer shell). The closest relation to it in that group would be Lead.Ununhexium will be part of the Oxygen series, so, again, we would expect it to have properties similar to those elements (e.g. 6 electrons in the outer shell). The closest relation to it in that group would be Polonium, which is also the first radioactive element.
One is magnesium. Other is Strontium. One below and one above Calcium in periodic table column.
This element is carbon.
The "metalloid elements", including at least As and Sb; many chemists would also include Ga, Ge, Te, and possibly Po.

it's in between gallium and arsenic so if gallium's atomic mass is 70 and arsenic's atomic mass is 75, 72 is right between them
Element 115 is in the same period as nitrogen and phosphorus as you go down the table these elements become more like metals. Immediately above 115 is bismuth which is a metal so 115 would be a metal also. Only a few atoms of element 115 have been made and they only last a few millionths of a second before decaying.
