What alkali earth metal is the most reactive in water?
Sodium is the alkali element that reacts most violently with water.
Which is most reactive alkali metals or alkaline earth metals?
Why are alkaline Earth metals less reactive than alkali metals? A: It takes more energy to remove two valence electrons from an atom than one valence electron. This makes alkaline Earth metals with their two valence electrons less reactive than alkali metals with their one valence electron.
Which alkaline earth metal is the second most reactive?
5.2 Alkaline earth metals The alkaline earth metals (beryllium, magnesium, calcium, strontium, barium, and radium) are the second most reactive metals in the periodic table (Table 3.7), and, like the Group 1 metals, have increasing reactivity in the higher periods.
Is radium the most reactive alkaline earth metal?
Alkaline earth metals make up group IIA of the periodic table of elements. They all exhibit a single oxidation state, +2, are light, and are reactive, though less so than the alkali metals. Barium and radium are the most reactive and beryllium is the least.
Which group 2 element is most reactive?
The alkali metals are the most reactive metals. Group 2 consists of the alkaline Earth metals. They are very reactive but less so than the alkali metals.
What are the most highly reactive metals?
The most reactive metal on the periodic table is francium. Francium, however, is a laboratory-produced element and only minute quantities have been made, so for all practical purposes, the most reactive metal is cesium.
What is the most reactive metal group?
alkali metals
The alkali metals are the most reactive metals. Group 2 consists of the alkaline Earth metals. They are very reactive but less so than the alkali metals.
What is the second most reactive element?
Reactivity series of metals
Order of reactivity | Metal |
---|---|
Most reactive | potassium (K) |
Second most reactive | sodium (Na) |
Third most reactive | calcium (Ca) |
Least reactive | magnesium (Mg) |
What is the most reactive group of metals?
Alkali metals
Alkali metals are among the most reactive metals. This is due in part to their larger atomic radii and low ionization energies. They tend to donate their electrons in reactions and have an oxidation state of +1.
What is the least reactive metal in the reactivity series?
gold
As we can see in the series, out of all the given options gold is the least reactive metal.
Why is alkali metals most reactive?
Alkali metals are among the most reactive metals. This is due in part to their larger atomic radii and low ionization energies. They tend to donate their electrons in reactions and have an oxidation state of +1. All these characteristics can be attributed to these elements’ large atomic radii and weak metallic bonding.
Which member of alkaline earth metal is least reactive?
Beryllium is the only alkaline earth metal not to react with water. One of its naturally occurring compounds is emerald. Calcium is needed for healthy bones, and plants need magnesium to form the chlorophyll molecules they use for photosynthesis.
Which alkali metal element is the most reactive?
As with all metals, the alkali metals are malleable, ductile, and are good conductors of heat and electricity. The alkali metals are softer than most other metals. Cesium and francium are the most reactive elements in this group.
Which metal is less reactive?
Based on its location on the periodic table, the metal that is likely to be less reactive than both strontium and sodium is magnesium (Mg). The answer is letter A. The rest of the answers are highly reactive.
What are the most and least reactive metals?
The least reactive metals would be Platinum, Gold, Palladium, Osmium and Silver and in the decreasing order. The inertness of the metals are due to the electron configuration in the orbitals.
