The periods are the rows, and the groups are the columns, so Fluorine, F, is in Period 2 (and Group 7).
The chemical symbol for fluorine is F.
Iodine, element number 53 is the halogen (Group 17) element in period 5.
The symbol for fluorine as an ion is F-.
The atomic symbol for fluorine is F.
Fluorine is abbreviated as a capital F, so "F"
F stands for fluorine. It belongs to halogen family
Fluorine is in the period 2, group 17 of the periodic table of Mendeleev.
From looking at the chart of the nuclides, you can determine that Fluorine has a total of 13 isotopes (F-15 through F-27). Only one of Fluorine's isotopes is stable (F-19) and makes up 100% of the naturally occurring fluorine. The other 12 Fluorine isotopes are all radioactive and have half lives ranging from 5 x 10E-22 seconds (F-15) to 1.83 hours (F-18).
The halogen in the 2nd period is fluorine (F).
