Br and Cl possess same properties. So he grouped them together.
They have similar properties.
Astatine is a member of the group 17 (halogens) of the periodic table of Mendeleev; the halogens are fluorine, chlorine, bromine, iodine and astatine.
Nitrogen: nitrogen is a pnictide, group 15 and period 2 in the periodic table of MendeleevBromine: bromine is a halogen, group 17 and period 4 in the periodic table of Mendeleev
These elements have similar properties.
Fluorine (and also chlorine, bromine, iodine) are all members of the halogens group; they are nonmetals, group 17, period 6 in the periodic table of Mendeleev.
Chlorine and iodine are members of the halogens family (group 17 of the periodic table of Mendeleev).
Chlorine, Bromine, and Iodine. They are all in the same periodic group.
Bromine is in Group 7: The Halogens, below Fluorine and Chlorine but above Iodine and Astatine.
Bromine and chlorine are in group VII A, which could also be designated Group 7a, of the narrow form periodic table that was commonly used before 1980. Most chemists now prefer a wide form periodic table, in which these elements are in column 17.
halogens (fluorine, chlorine, bromine, iodine and astatine)
Halogens: fluorine, chlorine, bromine, iodine, and astatine.
halogens are the non-metals in group 7A of the periodic table named as flourine, chlorine, bromine,iodine andastatine.
It's Chlorine because they are in the same group in the periodic table.
These elements are the halogens. Fluorine, chlorine, bromine and the rest in group 17 ( or group 7A ).
Elements in group 17 of the periodic table are called the halogens. The halogens are fluorine, chlorine, bromine, iodine, and astatine.
Group 17 of the periodic table contain: fluorine (F), chlorine (Cl), bromine (Br), iodine (I), astatine (At).
Group 17 elements are called halogens (fluorine, chlorine, bromine, iodine, and astatine)
We know that chlorine (Cl) and bromine (Br) are both halogens (Group 17 on the periodic table). As such, they do not form chemical bonds with each other but only mixtures.
You would get Sodium Chloride and Bromine. This is because Chlorine is a more reactive group 7, (halogen), element that bromine, we know this because it is above bromine in the periodic table group, it is therefore more electronegative. When the reaction occurs, the Chlorine displaces the Bromine and the solution turns brown.
The answer is chlorine, Cl. The order of group seventeen goes Fluorine F, Chlorine Cl, Bromine Br, Iodine I, Antimony At.
Halogens: fluorine, chlorine, bromine, iodine, astatine, Uus.
Together with bromine and fluorine they belong to the 'halogenes', group 7 in the periodic table.
F (fluorine) Cl (chlorine) Br (bromine) I (iodine) At (astatine)
They are called Halogens. the elements are: Fluorine, Chlorine, Bromine, Iodine and Astatine
