Questions

Why is chlorine is more reactive than iodine?

Why is chlorine is more reactive than iodine?

The outer shell of the chlorine is closer to the nucleus and it is less shielded than the outer shell of iodine. Therefore, chlorine attracts electrons. Chlorine is more reactive than iodine since chlorine can gain electrons more easily than iodine.

How is chlorine more reactive than bromine and iodine?

Use the results in the table to deduce an order of reactivity, starting with the most reactive halogen. 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.

Why is bromine less reactive than chlorine but more reactive than iodine?

Halogen displacement Structure strip State the order of reactivity of the halogens. The reactivity of the halogens decreases down the group. Therefore, chlorine is more reactive than bromine and bromine is more reactive than iodine. What is a displacement reaction?

How is chlorine more reactive than iodine?

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). Cl outer shell closer to nucleus (and less shielded) than iodine outer shell.

How is chlorine more reactive than iodine experiment?

Chlorine is more reactive than iodine as it is higher up in group 7. If we add chlorine water to potassium iodide solution, the chloride will react with the potassium to form potassium chloride and it displaces the iodine.

Why is chlorine more reactive than bromine ks3?

Yes, chlorine is more reactive than bromine because the chlorine atom has fewer shells and the electronic bonding is much stronger. The electrons are held closer to the nucleus. It is easier for chlorine to attract and hold electrons in its outer shell forming stronger bonds with other atoms.

Why is chlorine highly reactive?

Why does iodine react faster than bromine?

For bromine or iodine to react, each atom needs to gain an electron to fill up its shell so that it is in a more stable state. Since bromine has fewer shells, its outer shell is closer to the nucleus so, there is a stronger force of attraction of the positively charged nucleus on the outer shell of electrons.

Why is chlorine The most reactive halogen?

Halogens are notorious electron-hogs; powerfully attracting electrons from atoms of other elements, particularly from the alkali metals. This makes the halogens highly reactive. Chlorine, being one of the smaller halogens, will react strongly with most elements.
