In chemistry and physics, the atomic number (also known as the proton number) is the number of protons found in the nucleus of an atom and therefore identical to the charge number of the nucleus. It is conventionally represented by the symbol Z. The atomic number uniquely identifies a chemical element. In an atom of neutral charge, atomic number is equal to the number of electrons.

Atomic number - what does it indicate?
The atomic number represents the number of protons in the nucleus of an atom. It determines the element's identity and its position on the periodic table. Elements with different atomic numbers have distinct chemical properties.
What does the atomic number always indicate?
The atomic number always indicates the number of protons in the nucleus of that atom. There are no exceptions to this rule.
What does the atomic number of an element tell you about the element?
Atomic number = Number of protons
What is the term for the value that indicates the number of protons for an atom of a given element?
The atomic number is the number of protons in an atom of an element.
What is the atomic number of the element with the symbol Be?
The atomic number of the element with the symbol Be (Beryllium) is 4.
What does the atomic number indicate about an element?
The atomic number is the number of protons in the nucleus of one atom of the element.
What is the top number in the saquare in the periodic table indicate?
The top number in a square in the periodic table indicates the atomic number of an element. The atomic number represents the number of protons in the nucleus of an atom, which determines the element's identity.

What does atomic number indicate about an atom?
Atomic number is the number of protons in the nucleus of an atom. Each element has its own unique atomic number, which you can see on the periodic table, as the elements are arranged in ascending order of atomic number.
The number to the lower right on an element symbol indication the number of atoms of that element?
The number to the lower right on an element symbol is the atomic number, representing the number of protons in the nucleus of an atom of that element. It does not indicate the number of atoms of that element in a compound; that information is conveyed through subscript numbers next to the element symbol in a chemical formula.
