Question

Arrange the following as per the instructions given in the brackets-

Na, K, Cl, S, Si (increasing number of ionization energy) ​

Answer 1

________________________________________

$\sf\underline \color{teal}{Given \: elements:}$

K, Cl, S, Si, Na

$\sf \underline \color{teal}{To \: find:}$

Arrange the given elements according to the increasing number of ionization energy.

$\sf \underline \color{teal}{Solution:}$

As we know, ionisation energy is the energy required to move the outermost electron from a gaseous atom as ion.

So, the arrangement of given elements according to their increasing number of ionization energy will be as follows:

$\: \: \: \: \: {\sf{ \boxed {\blue{K<Na<Si<S<Cl}}}}$

Gᴏᴏᴏᴅ ᴍᴏʀɴɪɴɢ, ɪᴅɪᴏᴛ!!!~

Ionization energy increases across the period and decreases down the group.

Ionization energy increases across the period and decreases down the group.The order is : K<Na<Si<S<Cl
