Yes, alkali metals are more reactive than alkaline-earth metals. All atoms want to have 8 electrons in their outer shells. Alkali metals have to give one electron away, where as alkaline-earth metals need to give two away which is less energetically favorable.

Why alkali metals are more reactive than alkaline earth metals?

All atoms want to do is make their valence shell full. In alkali metals they have all of their shells completely full except one valence electron. The alkali metals REALLY want to get rid of that electron, so they will react with many elements/compounds to get rid of that electron. In alkaline earth metals they have all of their shells completely full except for two valence electrons. They also want to get rid of those electrons but the alkaline earth metals are not as desperate to do so as the alkali earth metals which make the alkaline much less reactive than the alkali metals.


What important characteristic do the alkali metals ad alkaline earth metals have in common?

Thet are all highly reactive. They react with oxygen (air) , water and acids. The further down the Groups, they become more reactive, to the point of explosion. The metals react with oxygen to form the metal oxide (bases). The metals react with water to form metal hydroxides (alkalis) and hydrogen The metals react with acids to form chemical salts and hydrogen . In terms of reactivity, Francium , reacts the same as other Group (I) & (II) metals, but is not found in the 'open' lab. because it is also radio-active.


What are the reactions with alkali metals and water like?

1) Alkali metals are stored in oil to minimise reaction with oxygen or water, it's a physical barrier towards air but the alkali metals still gradually corrode a traces of oxygen and water diffuse through. The reaction of alkali metals with water gets more violent for elements lower in the group e.g. (Li < Na < K < Rb < Cs). Adding them to water will cause an explosion due to the extremely exothermic nature of reaction, and can be rather dangerous and some alkali metals can react violently with just moisture in the air. Most of the alkali metals float on the top of the water, depending on how big the alkali metal is determines the size of the reaction this is because they're less dense that water itself and also during the reaction the alkali metals give of hydrogen gas which is quite flammable. Alkali Metal + Water » Metallic Hydroxide + Hydrogen The francium would be like any other alkali metal, it would be very violent like the other alkali metals.


Why do halogens react so easily with Alkali Metals?

The electron configuration is why they react. The Alkali metals have one electron in their outer shell and to complete their outer shell need 7 more electrons. They can give, take or share electrons with other atoms. This is when the Halogens come in handy. The Halogens have 7 electrons in their outer shells, and need one more to complete the outer shell. These can react very easily because they have both the perfect amounts to fill their outer shells and become compounds. Other atoms with other amounts to become atoms not ions needs another element to react with. Hope this helps, Matt.


Does alkali has a pH of over 12?

Some do. But all alkali have a pH value of more than 7.

All the alkali metals.


How does the chemical reactivity to alkali metal vary?

As you move down the alkali metal group on the periodic table, chemical reactivity increases. This is because the outermost electron in alkali metals is easier to lose as you go down the group, resulting in more reactive behavior with water and air. Lithium is the least reactive alkali metal, while cesium is the most reactive.


What is the meaning of highly reactive metal?

alkali metal. This means it generates and allows more energy to flow throught it


Is Ag more reactive than K?

Potassium (K) is more reactive than silver (Ag). Potassium is an alkali metal on the far left side of the periodic table, making it highly reactive with water and oxygen. Silver is a transition metal that is more stable and less reactive compared to alkali metals like potassium.


Would a metal in the boron family or alkali metal be more reactive?

A metal in the alkali metal family has one valence electron where as a metal in boron family has three valence electrons. It is easy to remove one valence electrons than three. So alkali metals will be more reactive.


What metal is alkali metal?

This is the first column in the Periodic Table. There are six metals that are "Alkali Metals" and six that are "Alkali Earth Metals". The Alkali metals are:LithiumSodiumPotassiumRubidiumCaesiumFranciumThese metals get more reactive as you go down the list...Hope I helped :D


Is alkali metal more reactive than transition metal?

Yes, alkali metals are more reactive than transition metals. This is because alkali metals have low ionization energies and readily lose their outermost electron to form positive ions, whereas transition metals have higher ionization energies and show a more variable reactivity depending on the particular metal and conditions.


What alkali metal element is less reactive than calcium?

it is the lithium metal. it is less reactivated.


Which group of metals is more reactive the alkali metals or the alkaline earth metals?

The alkali metals are more reactive.


What is the more reactive metal Cs or Na?

Cesium (Cs) is more reactive than sodium (Na) because it is located lower in the alkali metal group on the periodic table. This means that cesium has a larger atomic radius and lower ionization energy, making it more likely to lose an electron and react with other substances.


What element is to be more reactive lithium or neon?

Lithium by far, it is an alkali metal. Alkali metals are known to explode when they are placed in water (hydrogen gas is released). Nitrogen has two electrons to fill, and alkali metals have one electron to give off. Think of it as 2>1. Just know that lithium is more reactive than nitrogen.
