Why are fluorine chlorine bromine and iodine placed in the same group?
Wiki User

Fluorine, chlorine bromine and iodine have seven electrons in their valence shells, and they all need one electron to have stabilized electron configuration. Therefore they are grouped in Group 17 (halogen group) of Periodic Table.

What are the non metals in halogens?
All halogens are nonmetals, with the possible exception of astatine, which has no stable isotopes (its MOST stable isotope has a half-life of about 8 hours) and has never been observed in bulk. Astatine may be a semiconductor or even metallic in character; we just don't really know.
What properties do halogens have?
Halogens have many properties but the most important is the high reactivity and high electonegativity.let example of flourine it is so much high reactive that even if it react in dark still it will creat an explosion.
Does iodine float on water?
NO iodine can not dissolve in water but it can dissolve in benzene
Does a physical or chemical change occur when aluminum foil is placed into liquid bromine and a white solid forms?
Chemical
Is bromine a gas or liquid at room temperature?
Bromine is both a liquid and a gas at room temperature. It also depends on the volume it is placed in, there will be more visible gas when less compacted and visa versa.
What elements are more similar to chlorine?
Fluorine , Bromine , Iodine are similar to chlorine. They are non-metals placed in group-17.
Name three nonmetals on the periodic table?
Anything to the right of the step-like line.
What is an element in the periodic table that would have the same electron dot diagram as chlorine?
Fluorine, Chlorine, Iodine, and Astatine. You can find this out just from looking at a periodic table. (Electrons are what create the properties of atoms). Because of electrons and how they are placed around an atom all of the elements in the same group on the periodic table (vertical column) share the same properties. If you want to learn more as to why this is the case look up more about electrons.
What are the non metals in halogens?
All halogens are nonmetals, with the possible exception of astatine, which has no stable isotopes (its MOST stable isotope has a half-life of about 8 hours) and has never been observed in bulk. Astatine may be a semiconductor or even metallic in character; we just don't really know.
What element occurs naturally as a diatomic solid?
Hydrogen (H2) Nitrogen (N2) Oxygen (O2) Fluorine (F2) Chlorine (Cl2) Bromine (Br2) Iodine (I2) (Astatine [At] is placed in the halogen group but is a very short lived element. It is not known if it is diatomic so it's usually not considered)
What properties do halogens have?

Do fluorine and chlorine have the same chemical properties?
No. No two elements have the same chemical properties. However, the chemical properties of fluorine and chlorine are similar. Since they are similar, they are placed in the same group, group 17, on the periodic table.
What two element are out of order in periodic table?
It might be Iodine and Tellurium because Tellurium has a larger atomic weight than Iodine but Iodine has more similar properties with Fluorine and Chlorine so Mendeleev placed them that way to make more sense but at that point the elements were aranged in order of atomic mass. Now the periodic table is in order of it's atomic number rather than it's atomic mass so it all fits nicely.
How are chlorine and magnesium similar on the periodic table?
Chlorine and Magnesium are placed in same period. They are placed in period-3.
What does stand l for on the periodic table?
I stands for iodine. It is placed in group-17.
Is bromine an atomic element?
Yes. Bromine is an element. Its symbol is Br. It is placed in Group-17 of periodic table.
Is the Iodine in period 2 of the periodic table?
No , Iodine is placed in period-5 of the periodic table.
