Is iodine malleable or brittle?

Is iodine malleable or brittle?

Malleability, the ability of a material to be hammered out into a sheet (from the Latin, malleus, hammer , is a fundamental property of metals. Solid non-metals, e.g. diamond, sulfur, iodine, do not tend to have this property.

Which group is not malleable?

Nonmetals

Why is iodine not very reactive?

Because it has the largest atomic radius among the halogens, iodine has the lowest first ionisation energy, lowest electron affinity, lowest electronegativity and lowest reactivity of the halogens.

Does iodine displace bromine?

Bromine only displaces iodine from potassium iodide and the least reactive iodine cannot displace chlorine or bromine from their salts.

Is CL more reactive than Br?

Why: Chlorine is more reactive the bromine because chlorine radical is less stable then bromine radical.

What happens when potassium bromide and chlorine gas are mixed together?

When chlorine gas is passed through potassium bromide solution, potassium chloride and bromine are formed.

How can you tell how reactive a metal is?

The Reactivity Series

1. Add equal volumes of dilute hydrochloric acid or dilute sulfuric acid into a series of test tubes then add a equal mass of metal to each test tube.
2. Count the number of bubbles produced in a given time.
3. The faster the bubbles are given off, the faster the rate of reaction and the more reactive the metal.

What will happen when a less reactive metal is added to a metal salt solution?

In a displacement reaction: Displacement reactions are easily seen when a salt of the less reactive metal is in the solution. During the reaction: the less reactive metal coats the surface of the more reactive metal.

Does sodium oxidise faster than iron?

Salt. Salt accelerates the rusting process by lowering the electrical resistance of water. The more easily the electrons flow from iron to oxygen, the quicker the metal rusts.

Is Iron more reactive than zinc?

The higher the metal in the series, the more reactive it is and the more vigorously it reacts with water, oxygen and acid. Examples for metal-displacement reactions: Zinc can displace copper from copper sulphate solution and iron from ferrous sulphate solution. So zinc is more reactive than iron and copper.

Why is zinc so reactive?

The answer is that zinc is able to lose its outer electron more readily than copper. This phenomena occurs because copper metal is able to delocalize its outer electrons more readily than zinc. Since more energy is required for copper to react, we can say that zinc is more reactive than copper.
