If you're asking what element is number 17 on the Periodic Table the answer is Chlorine. Assuming this is for a chemistry class you should have a periodic table available to you and that would be rather easy to look up.
Fluorine (symbol F) is an element found in group 17 and period 2 on the periodic table
Element 17 in periodic table is Chlorine. Chlorine is a halide with 7 valent electrons.
The element in the Periodic Table that has 85 protons is Astatine. This element is in the Halogen Family (Group 17 in the Table). This group includes the elements Fluorine, Chlorine, Bromine, and Iodine.
The 11th element of the periodic table is Sodium (Na), which has an atomic number of 11. Sodium is a soft, silvery-white, highly reactive metal that is commonly found in table salt and various minerals.
Halogens F (fluorine), Cl (chlorine), Br (bromine), I (iodine), At (astatine)
Fluorine lies in Group 17, also known as the halogens, on the periodic table.
Bromine is an element on the periodic table. It has an atomic number of 35. It can be found near the right side of the table. Bromine is located in the Halogens group, which is group 7A or 17, and is also in period 4.
Astatine is a halogen; position in the periodic table of Mendeleev: group 17, period 6.
Group 17, period 2
Table salt, or sodium chloride, is a compound composed of two elements: sodium (Na) and chlorine (Cl). Sodium is a metallic element found in Group 1, Period 3 of the periodic table, while chlorine is a nonmetallic element found in Group 17, Period 3 of the periodic table.
Bromine is found in Group 17 of the periodic table, also known as the halogens. It is a nonmetallic element that is typically found as a diatomic molecule (Br2) in its natural state.
Carbon is not a family name; it is a chemical element that is found in group 14 of the periodic table. It is not part of the rare earth elements series, which are a group of 17 elements in the lanthanide series and actinide series of the periodic table.
