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.
I would expect element 117 (currently Ununseptium [Uus]) to continue the properties of the Halogens above it and have 7 electrons in it's outer shell. This would fit in with its systematic name also. Ununseptium.
Element 117 would be in the same group as the Halogens, like chlorine and iodine. So it wouldn't be a metal.
Ununseptium
which has still to be synthesised
Atomic number 117 is Ununseptium. It's group name is a Hollogen. It is a new element, not much is known about it to date.
Element 117 would most likely be a metalloid.
It is a non-metal.
