Graphically the difference is quite clear: the real numbers can be put on a line, the so-called number-line; while complex numbers are represented as points on a plane. A complex number is made up of two parts, like a vector in two dimensions.

The n-th root (where n is a natural number) of a real number x is defined as x^(1/n).
It was the successor to the successor of the number 0.
It is the space between two real numbers.
There are two types of numbers. The real number system that we use everyday for counting and money and such. There is also the imaginary or complex number system that is used to help evaluate the square roots of negative numbers. A 'real solution' generally means that the solution is one from the real number system. When solving an equation (especially at lower grade levels) the answer might be that there are no real solutions. However there might be complex solutions to the problem.
Yes, there are two main ways to number the groups on the periodic table: the IUPAC (International Union of Pure and Applied Chemistry) numbering system, which numbers groups from 1 to 18, and the older, simpler system which numbers groups from 1 to 8 (with some groups further divided into subgroups A and B).

A number system with a base of two is a binarysystem.
No. Not if the second number is zero.

Evolutionary mechanism work on the two subgroups independentlyWhen a group is split forces like natural selection and genetic drift affect the genes of the two subgroups differently. Mutations that arise in one group are not passed to the other group through reproduction.
Yes, a rational number is a real number. A rational number is a number that can be written as the quotient of two integers, a/b, where b does not equal 0. Integers are real numbers. The quotient of two real numbers is always a real number. The terms "rational" and "irrational" apply to the real numbers. There is no corresponding concept for any other types of numbers.

The properties of a subgroup would include the identity of the subgroup being the identity of the group and the inverse of an element of the subgroup would be the same in the group. The intersection of two subgroups would be a separate group in the system.
