Which of these four elements is the most reactive metal? na, rb, al, in

Sodium Na

Explanation:

Sodium is most reactive metal among these.

Sodium is present in group one.

It is alkali metal.

It has only one valence electron.

It need to lose the one valance electron to get the stability.

Sodium atom loses its electron to electronegative atom and get stable.

It loses its electron to halogens atom and form salt.

Na + Cl → NaCl

Its atomic number is 11.

Electronic configuration:

Na₁₁ = 1s² 2s² 2p⁶ 3s¹

we can see that 3s have only one electron which is lost by sodium metal and get stable.

they are made of gases.

they have a spherical shape.

they make energy through fusion.

> b takes place in the gas phase in an isothermal tubular reactor. the feed is one mole of a per one mole of c, an inert. the entering temperature and pressure are 427°c and 10 atm, respectively. the gas constant r = 0.08206 atm · l/mol · k.
