What is the least reactive metal Why?
Hint: Platinum is one of the rare metals on earth and is also called the noble metal as it is not found in combined states in natural surroundings. Complete answer: Platinum is the least reactive of all the options. Aluminium, iron are also formed in combined forms in the natural surroundings.
What is the least reactive group 1 metal?
lithium (Li)
Reactivity of Group 1 Elements The reactivity of alkali metals increases from the top to the bottom of the group, so lithium (Li) is the least reactive alkali metal and francium (Fr) is the most reactive.
Which is the least reactive metal in the reactivity series?
As we can see in the series, out of all the given options gold is the least reactive metal.
What are the 2 least reactive metals?
Silver, gold, and platinum are metals with the least reactivity.
Which group is least reactive?
Noble gases
Noble gases are nonreactive, nonmetallic elements in group 18 of the periodic table. Noble gases are the least reactive of all elements. That’s because they have eight valence electrons, which fill their outer energy level.
What is the least reactive transition metal?
The metals designated as the transition metals in the periodic table are much less reactive, and metals such as gold and platinum prop up the bottom of the series, exhibiting little in the way of chemical reaction with any everyday reagents.
What is the reactivity of Group 2?
2 (b) Reactivity of Group 2 Elements. The overall trend, for the reactivity of Group 2 metals with water, is an increase down the group. The outer electrons are easier to remove as they are further from the nucleus and there is more shielding resulting in a lower nuclear attraction.
What is the least reactive element in Group 2?
beryllium
The least reactive element in group 2 is beryllium. Even at red heat beryllium will not react with water and it does not react with dinitrogen (N2).
Which is the least reactive alkali metal?
The reactivity of alkali metals increases from the top to the bottom of the group, so lithium (Li) is the least reactive alkali metal and francium (Fr) is the most reactive.
Which is the least reactive metal gold or silver?
In a reactivity series, the most reactive element is placed at the top and the least reactive element at the bottom….The reactivity series.
| Element | Reaction with dilute acids |
|---|---|
| Copper | Very slowly |
| Silver | Barely reacts |
| Gold | Does not react |
Is sodium reactive or nonreactive?
Sodium is ordinarily quite reactive with air, and the reactivity is a function of the relative humidity, or water-vapour content of the air.
Is Tungsten a non-reactive metal?
Tungsten is a mostly non-reactive element: it does not react with water, is immune to attack by most acids and bases, and does not react with oxygen or air at room temperature.
What are the most reactive metals called?
Reactivity Trend in the Periodic Table The most reactive element is fluorine, the first element in the halogen group. The most reactive metal is francium, the last alkali metal (and most expensive element ). The least reactive elements are the noble gases. Metal can have multiple oxidation states and tend to have intermediate reactivity.
Which non metal is most reactive?
The most reactive non metals are the halogens, Group 7 on the periodic table. Fluorine is the most electronegative and most reactive non metal – it reacts with almost any other element or compound, organic or inorganic, including most of the noble (inert) gases.
Which element is the least reactive?
Generally, the least reactive elements in the periodic table are the noble gases. The group is made up of helium, neon, argon , krypton , xenon and radon.
What nonmetal that is highly reactive with a metal?
The more electronegative of the reactive nonmetals, such as oxygen and fluorine, are characterised by stronger nonmetallic properties and a tendency to form predominantly ionic compounds with metals. The noble gases are distinguished by their great reluctance to form compounds with other elements.
