Because it meets the criteria of the group and row as told and predicted by Mendeleev. The simplest reason it is in group 7 is because it has 7 electrons in it's outer shell!
Fluorine is an element, in group 7 of the periodic table.
Group 7 in periodic table, or 7 electrons in their outer shell.
Bromine is in Group 7: The Halogens, below Fluorine and Chlorine but above Iodine and Astatine.
Together with bromine and fluorine they belong to the 'halogenes', group 7 in the periodic table.
They are all in the same column (Group 7) of the periodic table and are also known as the halogens.
Fluorine is an element, in group 7 of the periodic table.
Group 7 in periodic table, or 7 electrons in their outer shell.
F stands for fluorine. It is placed in group-15.
Bromine is in Group 7: The Halogens, below Fluorine and Chlorine but above Iodine and Astatine.
Together with bromine and fluorine they belong to the 'halogenes', group 7 in the periodic table.
group 7.it consits of most electronegative elements such as fluorine,oxygen etc
They are all in the same column (Group 7) of the periodic table and are also known as the halogens.
Fermium (Fm) is in Group 7 in the Periodic Table.
All the elements in the same group as Flourine have similar properties. This group of elements is referred to as the halogens, and is located in group 7.
Group 7 of the periodic table.
Helium has completely filled orbitals and is place in group 18. It is chemically inert. Fluorine has 7 valence electrons and is the most reactive non metal on the periodic table.
Group 7 on the periodic table is called Halogens.
