How will astatine react with sodium?
Like the other halogens, astatine would be expected to form salts with metals such as sodium. Astatine can also react with hydrogen to form hydrogen astatide, which when dissolved in water, forms hydroastatic acid.
Is astatine reactive with iodine?
Its oxidation states vary from -1, +1, 3, 4 and 5. Bromine is more reactive than iodine, but not as reactive as chlorine. Also, bromine has two isotopes: 79Br and 81Br….Elements.
| Halogen | Configuration |
|---|---|
| Iodine | [Kr]4d10 5s2 5p5 |
| Astatine | [Xe]4f14 5d10 6s2 6p5 |
Is astatine more reactive than iodine?
Less reactive than iodine, astatine is the least reactive of the halogens. Its compounds have been synthesized in microscopic amounts and studied as intensively as possible before their radioactive disintegration.
Which halogens can be displaced by iodine?
The order of reactivity is chlorine > bromine > iodine. This is because chlorine could displace bromine and iodine, bromine could only displace iodine, but iodine could not displace chlorine or bromine.
Is iodine more or less reactive than chlorine?
Reactivity of these halogens correspond to its ability to gain an electron. Cl can gain an electron more easily than iodine – Cl more reactive. This is because Cl is higher up Group 7 than iodine (Cl: 2,8,7 electron configuration).
Why does iodine not react with sodium bromide solution?
Iodine does not react with sodium bromide solution is because chlorine can displace bromine and iodine, bromine can only displace iodine, but iodine can not displace chlorine or bromine.
Is there a reaction between astatine and potassium iodide?
Cl2 + 2KAt arrow 2KCl +At2 Chlorine + Potassium Astatide arrow Potassium Chloride + Astatine This happens because Chlorine is more reactive than Astatine so the chlorine displaces the Astatine to produce Potassium Chloride and Astatine. Is there a reaction between astatine and sodium iodide? No What chemical equation between astatine and water?
What happens when you mix astatine with iron?
Any chemical reaction; astatine is dissolved in water. What happens when you mix astatine with iron? How astatine react with iron? Which halogen reacts slowest with iron? Is there a reaction between astatine and sodium iodide? What is the equation for potassium iodide and astatine? Not known, probably no reaction.
Which is a stronger oxidizer, astatine or iodine?
You’d think astatine would oxidize (take the electron from) iodide, but At is a weaker oxidizer than I, so that’s out. However, if you look at the I2 and KI reaction, it forms KI3. KI3 contains a cluster of three iodine atoms, one of which has an extra pair of electrons.
What happens when astatine is mixed with sodium hydroxide?
Astatine react with sodium hydroxide and sodium trihydroxostannate (II) to produce astatide sodium and sodium hexahydroxostannate (IV).
