Why are neither the alkali metals nor the alkaline-earth metals found uncombined in nature?
Because these metals are very reactive and readily form compounds.
Why are neither theh alkali metals nor the alkaline-earth metals found uncombined in nature?
Due to their very high reactivity with oxygen and also water, they combine to form oxides, hydroxides and from there to carbonates and others.
Compare the solubilities of the lead compounds with those of the alkaline earth metals How are the solubilities similar and different?
Look at the position of Pb in the periodic table and the postion of the Alkali Earth metals. Alkali Earth Metals are in noble-gas configuration when they are doubly charged cations. Lead however is on the right hand side, and would like to have more electrons to get into that stablest configuration; making the bonds in lead-compounds more covalent -and stronger- in nature. Insoluble compounds have lattice enthalpies higher than the enthalpy of solvation. Now since Alkali Earth metals like to be in ionic states; their compounds will dissolve in general more easily than the same compounds with lead, since usually the lattice energy of lead compounds is much higher (In case of insoluble compounds higher than the energy that would be released upon solvation, which thus doesn't occur).
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.
Where does the term alkaline earth metals come from?
The alkaline earth metals come from the place that is described in their name: earth. They occur naturally in different types of earth.
Why are neither the alkali metals nor the alkaline-earth metals found uncombined in nature?
Because these metals are very reactive and readily form compounds.
Why are neither the alkali nor the alkaline earth metals found uncombined in nature?
Because these metals are very reactive and readily form compounds.
Why are neither the alkali metals or the alkaline-earth metals found uncombined in nature?
Alkali metals and alkaline-earth metals are highly reactive and easily form compounds with elements in the environment. Consequently, they are not found in their pure form in nature. Instead, they are typically found as compounds with other elements such as oxygen or sulfur.
Why are neither theh alkali metals nor the alkaline-earth metals found uncombined in nature?
Due to their very high reactivity with oxygen and also water, they combine to form oxides, hydroxides and from there to carbonates and others.
Why group 2A are called the alkali earth metals?
The name "Alkali" is given due to the alkaline nature of their oxides and hydroxides. The term "Alkali Earth Metals" is used as these metals are usually found as minerals in the Earth's crust.
What is family one called in the periodic table?
alkaline earth metals
Why are neither the metals nor the alkaline-earth metals found uncombined in nature?
Because these metals are very reactive and readily form compounds.
Is an metal acidic or alkaline?
Pure metals are neither, no pure element is and acid or an alkali, it is only compounds made from elements that have this property. When metals form compounds those compounds are typically alkaline.
What does non-alkali mean?
Non-alkali refers to substances or solutions that do not contain alkali metals, such as sodium, potassium, or lithium. These substances are typically neutral or acidic in nature, as opposed to alkaline. Non-alkali substances may include non-metal elements, non-alkaline earth metals, or organic compounds.
Are alkali metals always found pure in nature?
Alkali metals are not found as pure elements in nature.
Why are alkali metals not the alkaline-earth metals found uncombined in nature?
There are nothing uncombined. They are forming compounds inn nature.
Why are transition metals not as reactive as alkali metals and alkali earth metals?
transition elements are not as reactive as alkali metals or alkaline earth metals.. this is so because of the valence electronic configurations. alkali metals have ns1 configurations which have easy chances of loosing electrons so as to gain the stable state. Attaining a stable state is the law of nature. hence to attain it they have to redily donate electron. this is not so easily possible for the transition elements..
