Yes. The atomic number of an atom is the number of protons in its nucleus, which actually defines which element it is.


What do atomic numbers represent?

Atomic numbers represent the number of protons in an atom's nucleus. It also defines the element, as each element has a unique atomic number.


Can a single element have more than one atomic number?

No, each element has a unique atomic number that corresponds to the number of protons in its nucleus. Changing the number of protons would change the element itself.


Atoms have a set number of what in each element?

The number of protons in the nucleus of its atoms, which is its atomic number, defines each element. However, the nuclei of a given element may have varying numbers of neutrons.


Each element has been assigned a number what is it called?

The numbering arrangement of elements is called the atomic number. Atomic number determines the number of protons in an element's nucleus and defines its unique chemical properties.


What is the relationship between the atomic number of an element of protons of element possesses?

The atomic number of an element is equal to the number of protons that the element possesses. It is a unique identifier for each element and determines its placement on the periodic table. The number of protons also defines the chemical properties of the element.


The number of protons in an atom of an element?

The number of protons in an atom of an element is its atomic number. It determines the element's identity and is unique for each element. The number of protons also defines the element's chemical properties.

Protons are subatomic particles that determine the atomic number of an element. The number of protons in an atom's nucleus is what defines its atomic number; this uniquely identifies each element on the periodic table.


What does an atomic number tells you?

The atomic number tells you the number of protons in the nucleus. As such, it defines the element, since each element has a definite and defined number of protons. In the element, it also tells you the number of electrons, since the element (not the ion) has a neutral charge and protons = electrons.


What is the relationship between the atomic number and the elements identity?

The atomic number of an element determines its identity. Each element has a unique atomic number, which is the number of protons in the nucleus of its atoms. This number defines the element and distinguishes it from other elements on the periodic table.


What number determines what element an atom is from?

The number of protons in the atom's nucleus, known as the atomic number, determines what element the atom is from. Each element has a unique number of protons in its nucleus, which defines its unique chemical properties.
