Are alkali metals softer or harder than other metals?
The softness of alkali metals has to do with metallic bonding in terms of bonding and anti bonding orbitals. In molecular orbitals, there are the s, p, d orbitals with corresponding anti-bonding orbitals. For alkali metals, the s orbital is only partially filled. This means that the bonds between each atom are weak because only a cloud of s-orbital electrons are holding them together. As we move right across the periodic table the strength of metals reach a maximum at about group 7-8. This is because at this point anti-bonding and bonding orbitals are both partially filled and this maximizes the amount of unpaired electrons that participate in the electron cloud that holds metallic bonds together. As we proceed further right (toward Au) the bonds become weaker because the bonding and anti-bonding orbitals begin to fill and pair up. This means these electrons do not participate in the electron cloud of metallic bonding. Thus a weaker bond (softer metal) is formed.
Is alkali the only earth metal?
there are alkali metals and alkali earth metals but there is no such thing as an element called alkali...
Are alkali metals found as pure elements in sea water?
Alkali metals exist only as salts.
What name is given to group one elements in the periodic table?
The elements in Group 1 of the periodic table are called the alkali metals. The elements that make up this group are Lithium, Sodium, Potassium, Rubidium, cesium, and Francium. Hydrogen is not in this group even though it may look like it. The alkali metals are highly reactive metals that do not occur freely in nature. These metals have only one electron in their outer shell making them ready to lose that one electron in ionic bonding with other elements. Some other cool facts are: --Like other metals, alkali metals are malleable, ductile, and are good conductors of heat and electricity --The alkali metals are softer than most other metals. --Alkali metals can explode if they are exposed to water.
Why are the metallic bonds in an alkali metals relatively weak?
Alkali metals contribute only one valence electron
Is metallic bonding between metals or non metals?
between metals
Why the melting point boiling point and densities of alkaline earth metals are higher than alkali earth metals?
Alkaline earth metals do not exist , only alkali earth metals
What group would lithium be in on the periodic table?
They are in group one called the Alkali Metals.Those are alkali metals. They are the most reactive of all the metals, and they are in group 1 of the periodic table, all the way to the left.
Why the group 1 element of periodic table are called alkali metals?
Group 1A elements are active metals. They are so active that they are never found free in nature. They are usually stored in oil. They form compounds with oxygen that dissolve in water to give solutions that are alkaline or caustic. They are called alkali metals, or simply the alkalis.
Do alkali metals give or take electrons?
Alkali metals GIVE electrons (the only one electron that they do have) so that they may become balanced.
Metals that are so reactive that in nature they are found only combined with other elements?
Alkali Metals
Why do alkali metals have lower ionization energies than the alkali earth metals?
Alkali gases only have 1 electron needing to be removed to reach a stable noble gas configuration. Alkaline earths have two electrons. Alkali metals thus have the lower ionization energy of the two groups.
