(1) Polymeric, Dimeric, Monomeric
(2) Dimeric, Polymeric, Monomeric

(4) Polymeric, Monomeric, Dimeric
A particle is moving along x-axis with its position ($ x $) varying with time ($ t $) as:
$ x = \alpha t^4 + \beta t^2 + \gamma t + \delta. $
The ratio of its initial velocity to its initial acceleration, respectively, is:
Group one of alkali metals is s-block elements with just one electron in their s-orbital. They are are alkali metals. They are named so because of the alkaline nature of the hydroxides and oxides.
Alkali metals are characterized by one s-electron in the valence shell of their atoms.
Alkali metals have a corresponding [Noble gas] ns1 electronic configuration. They occupy the first column of the periodic table. Alkali elements are:
They have occupied successive periods from first to seven. Francium is a radioactive element with very low half-life.
This makes them the most electropositive elements and due to the same reason, they are not found in the pure state.
