The unit for the amount of electric charge is the coulomb.The amount of charge that passes any particular place in one second is called the "current"; the unit is the ampère.
It makes no difference whether the circuit is parallel, series or complex. The number of electrons travelling (or oscillating back and forth for AC) is determined by the current (amps). 1 amp = 1 coulomb/second. 1 coulomb = the charge represented by 6.24150962915265 x 1018 electrons. The current in each leg of a parallel circuit has to be worked out separately.
The group of the element indicates the amount of valence electrons. For example, the alkali metals have one valence electron and is in group one whilst the halogens have seven valence electrons and are in group seven.
No. it is the term used to tell the electrons in an atom.
The electrons on the outermost shell of an atom tell you how many valence electrons an atom on the periodic table has , and this number can be used to apply to the octect rule .
Tell you the number of protons and electrons in an atom
How fast the vehicle is traveling.

A compass will tell you which direction you are traveling in.

Its electric charge polarity. If (+) it is missing electrons, if (-) it has extra electrons.
You need at least two components in your circuit before you can tell whether it's a series circuit or a parallel one.
