Which Alkali metals would undergo the least exothermic reaction with chlorine?
Cesium would undergo the least exothermic reaction with chlorine among the alkali metals. This is because cesium is the most reactive alkali metal, so it requires more energy to form a compound with chlorine compared to the other alkali 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.
What are two most important alkali metals?
The two most important alkali metals would be sodium and potassium.
Is hydrogen a alkali metal or alkaline metal?
Alkali metals can be substituted for hydrogen. Any of them. They include lithim (Li), sodium (Na), potassium (K), rubidium (Rb), cesium (Cs) and francium (Fr). The alkali metals are in group one of the periodic table of the elements, and are all stacked up in the column below hydrogen. All the alkali metals are all organized with a lone electron in their outer most shell, or valence shell (in the neutral atom) and all of the alkali metals would like to loan out that electron to anything that would like to borrow it. It turns out that the reactivity of alkali metals are least to greatest from the top of the column to the bottom. This is because of electron screening.

What subscripts would you most likely use if an alkali metal and a halogen formed an ionic compound?
I would most likely use a +1 subscript for the alkali metal and a -1 subscript for the halogen in an ionic compound, as alkali metals typically form ions with a +1 charge and halogens typically form ions with a -1 charge.

What is an alkali metal which would melt?
All the alkali metals will melt.
What are two most important alkali metals?
The two most important alkali metals would be sodium and potassium.
What would be least likely to pollute water with heavy metals?
Lumber mills are least likely to pollute water with heavy metals. Did you know that Zinc, copper, and lead are three of the most common heavy metals released from road travel.

Which element is likely to combine with a nonmetal K Ar F or Br?
K, potassium being a metal is highly reactive towards non metals.
What subscripts would you most likely use if an alkali metal and a halogen formed an ionic compound?
I would most likely use a +1 subscript for the alkali metal and a -1 subscript for the halogen in an ionic compound, as alkali metals typically form ions with a +1 charge and halogens typically form ions with a -1 charge.
Is lithium hard?
No, in comparison to the rest of the metals, lithium (as an alkali metal) would be called a soft metal. All the alkali metals could be cut with a knife, but still retain properties of metals.
What would be the result when alkali metals react with oxygen?
Basic oxides
Why are the alkali metals never used as a structural material?
Alkali metals tend to react quite violently with water, so if it rained any structure built out of them would be destroyed.
Which element when combined with chlorine would most likely fom an ionic compound?
Among the naturally occurring elements, the most likely one would be cesium, the least electronegative of all elements. In practice, any of the other alkali metals and any of the alkaline earth metals would usually react readily with chlorine gas, as would many of the transition metals.
