Its atomic structure.
For chemical properties it is the configuration of valence electrons (1 .. 8).
For physical properties it includes the structure of the nucleus and all electron orbitals.
protons in its nucleus, which defines the element.
The number of protons defines the element.
Atomic number
The subatomic particle that defines the element is the proton. The number of protons in the nucleus of an atom determines the element's atomic number, which differentiates one element from another on the periodic table.
The number of protons identifies this element as aluminum, which has an atomic number of 13. The number of protons is an element's atomic number on the periodic table. Every element has its own unique atomic number which defines it as that element.
Yes. The number of protons defines the element.
Carbon - the element that defines the chemical word "organic".
Atomic number
The number of protons determines the element, and is the same as its atomic number.
If the number of protons changes so does the element, as the number of protons defines the element.
Suppose the function, y = f(x) maps elements from the domain X to the range Y. Thenfor every element x, in X, there must be some element y in Y, andfor an element y, in Y, there can be at most one x in X.
The key element that defines emotional and artistic expression in music is the use of melody, harmony, rhythm, and dynamics to convey feelings and evoke a response from the listener.
