As there are 4 numbers and they are all different, they can be arranged in: 4 choices for first number, leaving 3 choices for the second number for each choice of the first, leaving 2 choices for the third number for each of the choices of the first two, leaving 1 choice for the last number for each of the choices for the first three giving: number of choices = 4 x 3 x 2 x 1 = 24 possible orders in total.
6 X 5 = 30: There are 6 possible winners, and with the winner chosen, there remain 5 possible second place finishers. The choices are independent, so that the number of possible choices is the product of the two individual place choices.
The answer is 6! which is 6*5*4*3*2*1 = 720. Think of it as the first number you have 6 choices, the next number you have 5 choices, the next number you have 4 choices and so forth.

Assume you have 6 spots shown below: _ _ _ _ _ _ In the first spot, you have 6 letters to choose from. In the second spot, you have 5 letters to choose from because you already used one. Similarly, in the remaining spots, you will have 4, 3, 2, and 1 letters to choose from. So you have 6 choices * 5 choices * 4 choices * 3 choices * 2 choices * 1 choice = 720 possibilities

Every element has a different number of protons and electrons in each atom, and this amount is what the atomic number tells you.

Because it is ions that are charged. Basically the same reason why we distinguish mammels from reptiles: they are different. Atoms/neutrals are different from ions/not-neutrals because they are different. equal number of protons and neutrons equal number of protons and neutrons

Assuming that zero cannot be used for the first digit then this can be selected from numbers 1 - 9 (9 choices), and the 2nd, 3rd and 4th digits from 0 - 9 (10 choices). The total number of different ways is : 9 x 10 x 10 x 10 = 9000.
