Alkali metals are electropositive so they want to react with halogens which are more electronegative.
Basic character depends upon electron loosing tendency of an element which increases down the group,SO basic character of alkali metals increases down the group
They are actually called the alkali metals. They are called the alkali metals because many of the compounds they form are bases (alkaline) and in pure form they will react with water to produce strong bases.
1.Both are differ in valency shell electrons 2.I-A are monovalent and II-A are divalent 3.I-A is more reactive then the II-A group . 4.I-A have more electro positive character and II-A have less electro positive character than the I-A group . 5.I-A have less ionization energy and II-A have high ionization energy than the I-A . 6.I-A have very less electro negativity than the II-A group elements. 7.I-A is soluble in water and II-A is insoluble in water . 8.I-A metals are does not react directly with nitrogen but II-A react with nitrogen directly. 9.I-A group elements are strong reducing agents than the II-A group elements. 10.The oxidation values are differ. 11.I-A obtained in solid state but II-A group in solution state 12.Decomposes on heating I-A give only oxygen but II-A group liberates both oxygen and nitrogen .

Group 17 elements are acceptors of electrons and group 1 elements ar donor of electrons.
Alkaline metals: Li, Na, K, Cs, Rb, Fr.
Usually halogens are called as salt producers,their electronegativity is high compared to other elements.They easily combine with electropositive metals and result in formation of salts.
Ionic hydrides are formed by the reaction of hydrogen gas with the most electropositive metals. (group 1 and 2 excluding Be and Mg) The reaction involves the forming of a crystal lattice (solid). Covalent hydrides are formed by weakly electropositive metals and are primarily gasses at room temperature.
Yes there is a mnemonic for the spectrochemical series. It is: "C.B.A.S.E.F.A.G.H.I". This acronym stands for the following order: C - Cation B - Base A - Acid S - Strong E - Electropositive F - Formation A - Anion G - Group H - Hyperconjugation I - Inductive Effect. C - Cation B - Base A - Acid S - Strong E - Electropositive F - Formation A - Anion G - Group H - Hyperconjugation I - Inductive EffectBy remembering this mnemonic you can easily recall the order of the spectrochemical series.

Group 1-12 (all metals). Group 13-16 contains metals, metalloids as well as non-metals.
Down a group, the number of shells increases, also the atomic size. Thus , the metallic character increase does increase as going DOWN a group. It is easy to remove an electron froman atom of bigger...
