Yes.
A. Alkali metals have the large radii and low atomic weights
apparently due to another answer to a very similar question, all alkali metals are solid
Alkali metals are from Group 1 of the Periodic table and have a single electron in their outer shell. Alkaline-Earth metals are in group 2 of the periodic table and have 2 electrons in their outer shell.
Alkali Metals: the alkali metals are found in the first group of the periodic table, Alkali metals are very reactive metals and they are not freely in their nature, alkali metals have one electron in their outermost shell. therefore alkali metals are ready to loose that one electron for bonding with other elements, alkali metals are good conductor of electricity and heat. they are soft in nature than other metals.The Alkali Metals are:lithium, sodium, potassium, rubidium cesium, francium
Unstable in air or water, they oxidize rapidly and sometimes violently.

No. The alkali metals in particular have very low densities; the only elements with a lower density than lithium at room temperature are the ones that are gases. Carbon, sulfur, bromine and iodine are all denser than all the alkali metals and several of the alkaline earth metals. Iodine is denser than aluminium and titanium.

Alkali metals have only one valence electron and all of these elements are highly reactive. All of them are metals. Except lithium, other elements can be cut by a blade. They have a lesser density than water.
The density of francium hydroxide was not estimated; an approximate estimation can be made by comparison with the alkali metals hydroxides.
Yes, both the alkali metals and the alkaline earth metals with react with oxygen. The alkali metals will do so rapidly even at room temperature, cesium and rubidium self-ignite on contact to air.
Unstable in air or water, they oxidize rapidly and sometimes violently.
Since the temperature isn't high enough to excite transition metals, the method is selective toward detection of alkali and alkali earth metals.
It is alkali metals
Alkali metal forms Alkali while metals form bases.
