What element is most reactive in the group 7a?
Fluorine (F) is the most reactive element in group 7A (also known as group 17 or the halogens). It has a strong tendency to gain an electron to achieve a stable octet configuration, making it highly reactive.
Similar for all halogens?
All halogens are highly reactive non-metallic elements with similar chemical properties. They form diatomic molecules in their elemental state (F2, Cl2, Br2, I2) and have a tendency to gain one electron to achieve a full valence shell, resulting in a -1 oxidation state in their compounds. They exhibit increasing molecular size and decreasing reactivity down the group.
Are all halogens diatomic molecules?
Yes, all halogens are diatomic molecules in their elemental form, meaning that they exist as pairs of atoms bonded together. Examples of halogens include fluorine (F2), chlorine (Cl2), bromine (Br2), iodine (I2), and astatine (At2).
Which halogen reacts fastest with iron?
The group sevens non-metals get less reactive the further down the table they fall, making fluorine the most reactive and iodine least reactive. So based on this i would say that fluorine reacts fastest with iron (:
How many molecules are in 85g of Fluorine gas?
1 mole F2 = 37.996g F2 = 6.022 x 1023 molecules F2 85g F2 x 6.022 x 1023 molecules F2/37.996g F2 = 1.3 x 1024 molecules F2
What element is most reactive in the group 7a?
Fluorine (F) is the most reactive element in group 7A (also known as group 17 or the halogens). It has a strong tendency to gain an electron to achieve a stable octet configuration, making it highly reactive.
A chemical family whose members exist as reactive diatomic molecules in the gaseous phase?
The halogens are a chemical family whose members exist as reactive diatomic molecules in the gaseous phase. Examples include chlorine (Cl2) and fluorine (F2).
Which one in the following is the strongest oxidising agent between F2 Cl2 Br2 I2?
Fluorine (F2) is the strongest oxidizing agent among the listed halogens. It has the highest electronegativity and is the most reactive due to its small atomic size, making it a powerful oxidizing agent.
What pale yellow gas is considered the most reactive of all of the elements?
Fluorine gas, F2
Which is most reactive element?
Fluorine(F2) is the most reactive element, known to react with even Xenon, Krypton, Gold, Platinum, etc.

How is fluorine classified?
Fluorine is classified as a nonmetal in the periodic table. It belongs to Group 17, which is known as the halogens. Fluorine is highly reactive and is found in nature primarily as the diatomic molecule F2.
Why inter halogens are more reactive then halogens?
If they are more reactive, I would speculate it is due to their differences in electronegativities. The greater the difference, the more stable the compound. Electronegativities decrease as you go from F to I. For example, ClF3 reacts more violently than F2, yet IF7 is chemically inert. http://en.wikipedia.org/wiki/Interhalogen
What are two properties of halogens?
different Halogens have different properties such as flourine: has an extremely low melting point of the top of my head it's somewhere around -249000 degrees centigrade unlike bromine which has a higher melting point flourine's colour is a green and grey
Are all halogens diatomic molecules?

Which diamtic molecule has a single bond?
There are a few possibilities:- H2, F2, Cl2, Br2, I2 mixed halogens such as ClBr
What family of elements most often exist as diatomic molecules?
The halogens (Group 17) are the family of elements that most often exist as diatomic molecules in their elemental form. This includes elements like chlorine (Cl2), fluorine (F2), bromine (Br2), and iodine (I2).
