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...

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 are equal.Answer and Explanation: a. 8: Oxygen O b. 78: Platinum Pt c. 17...
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 ...
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...

Every element is defined by the number of protons in the nucleus of their atoms. This number cannot change without the atom becoming a different element. However, the number of neutrons in the nucleus can change. These variations are called isotopes and they are differentiated by listing their ...
The beta decay is the decay of electron or positron from a radioactive nucleus. The atomic number of an atom is the number of protons present in the nucleus and the mass number is the total number of protons and neutrons present in the nucleus....
