Is iodine highly reactive?
Iodine is a non-metallic, dark-gray/purple-black, lustrous, solid element. Iodine is the most electropositive halogen and the least reactive of the halogens even if it can still form compounds with many elements. Iodine sublime easily on heating to give a purple vapour.
Which is more reactive fluorine or oxygen?
Fluorine is the most reactive because it has the strongest attraction for oxygen. We say that fluorine is electronegative. Since electronegativity decreases going to the left of the periodic table, oxygen is the second most reactive element on the list.
Why oxygen is less reactive than fluorine?
Fluorine has a smaller atomic radius than oxygen. This means that the size of fluorine’s electron cloud is smaller, and it has a greater ability/tendancy to attract a bonding pair of electrons (thus a higher electronegativity) than oxygen as it has a higher nuclear charge and a smaller atomic radius.
Which one of them is least reactive?
Platinum is the least reactive metal. It has remarkable resistance to corrosion, even at high temperatures, and is therefore considered a noble metal. Consequently, platinum is often found chemically uncombined as native platinum.
Which of the following is the least reactive?
Black phosphorus is thermodynamically most stable form of phosphorus as it is a highly polymerised form of phosphorus. Hence it is least reactive.
Why is gold least reactive?
The reason bulk gold solid is largely unreactive is because the electrons in gold fall at energies which few molecules or chemicals match (i.e., due to relativistic effects).
Which is the least reactive metal gold?
The lightest or least dense metal that is a pure element is lithium, which has a density of 0.534 g/cm 3. In the reactivity series, copper, gold, and silver are at the bottom and hence are least reactive.
Why is gold and silver least reactive?
Answer. silver(e.g) is a good conductor of electricity because of its sea of delocalised electrons between the layers of metal ions. However it is not highly reactive because you would need a lot of energy to break the metallic bonds within each of those layers.
Which is most reactive silver or gold?
Although gold and silver are in same column in periodic table silver is more easily oxidized than gold.
Which elements are non reactive?
What Are Noble Gases? Noble gases are nonreactive, nonmetallic elements in group 18 of the periodic table. As you can see in the periodic table below, noble gases include helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and radon (Rn). All noble gases are colorless and odorless.
Is silver a reactive metal?
Together with gold and the platinum-group metals, silver is one of the so-called precious metals. Silver is one of the noblest—that is, least chemically reactive—of the transition elements.
Is Silver reactive?
Under standard conditions silver is a soft metal that has a shiny metallic finish. Silver is not very reactive. It will not react with air or water. It will tarnish, however, when coming into contact with sulfur compounds.
