Each isotope of an element has an Atomic Mass. The average of all the atomic masses of an element's isotopes gives an elements atomic weight. For this reason, atomic weights are decimal numbers.
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.
Henry Moseley found the relationship between the wavelengths of x-rays and the atomic number of elements. He proposed that the atomic number of an element is better defined by the number of protons in the nucleus rather than by its atomic mass.
The atomic number represents the number of protons in an atom's nucleus, while the number of nucleons includes both protons and neutrons. The atomic number uniquely identifies an element, while the number of nucleons determines the atom's mass.
The proton number, or atomic number, is the number of protons in an atom's nucleus, and it determines the element's identity. Each element has a unique atomic number, so elements are defined by the number of protons they possess.
The relationship between an element's mass and its atomic number is linear because the mass of an atom is primarily determined by the number of protons and neutrons it contains. As the atomic number increases, so does the number of protons and neutrons in the nucleus, leading to a proportional increase in mass. This linear relationship is a result of the fundamental structure of atoms and the way in which they are composed.

The atomic number of an element represents the number of protons in the nucleus of an atom. It is a unique identifier for each element on the periodic table. The number of protons in an atom determines the element's chemical properties and its place in the periodic table.

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.
Atomic number: number of protons in a nucleus unique to an element Atomic Mass number: number of protons + number of neutrons in a nucleus. May be a small range of values for a given element. Very roughly the atomic mass number is double the atomic number. For large elements it is more than double.
The atomic number and number of protons are always the same in a normal element.
The atomic number represents the number of protons in an atom's nucleus, while the number of nucleons includes both protons and neutrons. The atomic number uniquely identifies an element, while the number of nucleons determines the atom's mass.
The proton number, or atomic number, is the number of protons in an atom's nucleus, and it determines the element's identity. Each element has a unique atomic number, so elements are defined by the number of protons they possess.
Atomic number 27 : Cobalt Atomic number 28 : Nickel Atomic number 29 : Copper Atomic number 30 : Zinc Atomic number 31 : Gallium
sodium chloride is a salt, a type of compound, not an element. it has no atomic number.
the atomic number is the number of protons in a certain element. elements are arranged on the periodic table by atomic number in increasing order
The atomic number of an element is the number of protons in its nucleus, which determines its effective nuclear charge. In the case of oxygen, which has an atomic number of 8, the effective nuclear charge is the attraction felt by the outermost electrons towards the nucleus, and it increases as the atomic number increases.
