Recall now that the electrons of elements with increasing atomic number (the number of protons in the nucleus and, therefore, the number of orbital electrons in a normal, un-ionized, atom) occupy the states with lowest energy. The lower energy states are, in general, the quantum states with...

How many protons are in an isotope of sodium with a mass number of 25? What is the relationship between atomic mass and mass number? What is relative atomic mass? What is the atomic number of germanium? An atom has an atomic number of 12 and a mass number of 25. how many neutrons ...
The atomic number is the absolute definition of an element and gives a factual basis for the ordering of the periodic table.[85] In other words, since the atomic number of an element is the same as the number of protons in its nucleus, the modern periodic table arranges the elements accor...
Atomic number Z represents the number of protons per atom. Mass number Z + N is equal to the number of protons Z plus the number of neutrons N present in the nuclei. Mass numbers of the most abundant isotopes are given in order of decreasing abundance. For example, Cadmium Cd-48 mass ...
of an atom represents it. It represents the number of protons that an electron in the element effectively ‘sees’ due to screening by the inner-shell electrons. Generally, the EAN of the central metal is numerically equal to the atomic number of the noble gas element found in the same ...
The mass number of lithium is 7. The mass number of any element is equal to its number of protons and neutrons. You can figure out the number of... Learn more about this topic: Atomic & Mass Number | Overview & Difference from
Isotopes are two or more forms of an element. Isotopes differ from each other according to their mass number. The number written to the right of the element's name is the mass number. The mass number represents the number of protons plus neutrons in the nucleus of an atom of the element...

The atomic number uniquely defines an element. Each element has its atomic number. The atomic number is also equivalent to the number of protons present in the nucleus of the atom. For neutral atoms, the number of protons and the number of electrons a...
