In a way, passing an array as argument always loses a dimension. The reason behind is that, for historical reasons, arrays cannot be directly copied, and thus what is really passed is a pointer. This is a common source of errors for novice programmers.
atomic number represents the protons in atom. As a example hydrogen has one proton and atomic number is 1.
The periodic table contains an enormous amount of important information: Atomic Number: The number of protons in an atom defines what element it is. For example, carbon atoms have six protons, hydrogen atoms have one, and oxygen atoms have eight.The number of protons in an atom is referred to as the atomic number of that element.The number of protons in an atom also determines the chemical behavior of the element. Element Symbol: The element symbol is one or two letters chosen to represent an element (H for hydrogen, etc.).These symbols are used internationally. Atomic Weight: The standard atomic weight is the average mass of an element in atomic mass units (amu).tomic Number: The number of protons in an atom defines what element it is. For example, carbon atoms have six protons, hydrogen atoms have one, and oxygen atoms have eight. The number of protons in an atom is referred to as the atomic number of that element.
