The atomic number is equal to the number of protons and neutrons in a neutral atom.
Positive charged particles in atomic nucleus - protons. Number of protons = atomic number (The number of a given element in the Mendeleev table)
The "Atomic number" of an element corresponds to the number of only the protons in the nucleus of its atoms. Add to that the number of neutrons that are also in there, and you have the "Atomic weight".
Atomic number is the number of protons in the atomic nuclei of the atoms of an element.
how do you find the atomic number for an element?
An atomic number is actually related to an element and not an atom. Therefore, the question is not relevant. It is NOT atoms that have an atomic number; it is the element.
Atomic number is the number of protons in the atoms of a particular element. Each element has its own unique atomic number.
Atomic number and atomic mass are not alike. Atomic number is the number of protons in the nuclei of the atoms of an element. Each element has a unique atomic number. Atomic mass is the combined masses of the protons, neutrons, and electrons of the atoms of an element. Individual isotopes of an element have specific mass numbers, which are the sum of the protons and neutrons in the nuclei of the atoms of the isotope.
One element differs from another element by the number of protons in their atoms. The number of protons in the atom is known as the atomic number. Also one isotope of an element differs from another isotope of the same element by the number of neutrons in their atoms.
Atomic number is the number of protons in an atom, not the number of atoms. The element with the atomic number 15 is phosphorus.
The atomic number of an element is the number of protons in the nuclei of its atoms, and is unique to each element.
The atomic number of an element is the number of protons in its nucleus. The number of protons define what the element is.
Atoms of the same Element have this.
