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 else can I help you with?
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.
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?
A chemical change occurs. When aluminum foil is placed in liquid bromine, the aluminum reacts with bromine to form aluminum bromide, which appears as a white solid. This reaction is a chemical change because the composition of the substances involved is altered.
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.
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.
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 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.
Name three nonmetals on the periodic table?
Anything to the right of the step-like line.
Where are the halogens arranged?
The halogens are located in Group 17 of the periodic table, also known as the "halogen group." These elements include fluorine, chlorine, bromine, iodine, and astatine. They are highly reactive nonmetals with seven electrons in their outermost energy level.
Why was bromine placed in its placement in the periodic table?
Bromine is placed in its position in the periodic table because it has similar chemical properties to other halogens in its group, such as chlorine and iodine. In the periodic table, elements in the same group tend to have similar properties due to their electron configurations. Bromine's position in Group 17 (or Group 7A) reflects its valence electron configuration and allows for easy prediction of its chemical behavior.
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)
Is halogen an element belonging to group 17 of the periodic table?
halogens are the element placed in the 17th group of the period table. they have valency 1 and are the most reactive and the most electronegative elements.Halogens include flourine,chlorine,bromine,iodine and astatine (the radioactive element) their electronegativity decreases down the group. halogens are also called as salt forming elements.
Why is hydrogen classified as a halogen?
Hydrogen is not classified as a halogen. Halogens are a group of elements on the periodic table that includes fluorine, chlorine, bromine, iodine, and astatine. Hydrogen is a nonmetal element that belongs to a different group on the periodic table.
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.
Why did Mendeleev place iodine in the same group as fluorine?
Mendeleev placed iodine in the same group as fluorine because both elements have similar chemical properties, such as forming compounds with similar stoichiometry and showing similar reactivity patterns. This classification allowed Mendeleev to identify a pattern in the properties of elements and lay the foundation for the modern periodic table.
Where are the most reactive non-metals in the periodic table placed?
The most reactive non-metals in the periodic table are typically found in Group 17, also known as the halogens. This group includes elements like fluorine, chlorine, bromine, and iodine, which exhibit high reactivity due to their tendency to gain electrons to achieve a stable electron configuration.
