It should belongs to group 17.
This artificial element exist - ununseptium (temporary named) with the symbol Uus. It is in "Group 17".
An isotope is where an atom has a different number of neutrons than what it should be.e.g.Gold has 79 protons and 118 neutrons = 197 nucleons.But some gold atoms are strange they only have 117 neutrons.They are isotopes.
Assuming this is an atom, 78 electrons means there are 78 protons, so this is platinum. The mass number will be 78 + 117 = 195 so the complete symbol will be 195/78 Pt where I've used the / to represent that 195 is a superscript and 78 is a subscript.

Because it has a very hight number an its is famously colorful

Ununseptium has 117 protons.
Platinum atom has 78 protons and electrons; the number of neutrons is variable and depends on the atomic mass of the isotope (atomic mass of the isotope - atomic number = number of neutrons). The stable isotopes have 114, 116, 117, 118, or 120 neutrons.
There are 78 protons and 78 electrons present in a platinum atom. There are also at least 114 neutrons in the five stable isotopes. 192 Pt = 114 194 Pt = 116 195 Pt = 117 196 Pt = 118 198 Pt = 120
One with 117 protons.
Gold
All isotopes/ions of Platinum have the same number of protons: 78. If it had a different number of protons, then it would be a completely different element. The only subatomic particles that change in an atom are the electrons and neutrons. The most common isotope of Platinum is 195Pt with 117 neutrons.
Iodine has 53 protons.
