C. The maximum energy required to move one electron to the valence shell.
<span>The scientific use of
the term digital is much different from the common use because the term digital
in science is a way of describing a discontinuous phenomenon or something that
is just finite and limited. It also represents a data in figures with the use
of this term.</span>
There are two kinds of mixtures
a) homogeneous : the boundary of the two components is not physically distinct
b) heterogeneous:the boundary of the two components is physically distinct
the following separation techniques are common for mixtures
1) filtration: if the two components are forming heterogeneous mixture we can separate them by filtration.
2) boiling: if boiling point of one of the components is less than other
3) magnetic separation: if one of the component is magnetic
4)sieve method: for solid components with difference in size of particles
5) hand picking
Thus the correct match will be as shown in the figure
