WebJun 9, 2024 · Atomic Number. The atomic number (Z) of an element is the number of protons in the nucleus of each atom of that element.An atom can be classified as a particular element based solely on its atomic number. For example, any atom with an atomic number of 8 (its nucleus contains 8 protons) is an oxygen atom, and any atom with a different … WebSep 30, 2015 · A quick look in the periodic table will show you that chromium's atomic number is equal to 24 and manganese's atomic number is equal to 25. This means that you can write chromium-51 = 51 24Cr manganese-51 = 51 25Mn The nuclear equation for this decay will look like this 51 24Cr → 51 25Mn +?
This element also has two meta states, 45m Cr, the more stable one, and 59m Cr, the least stable isotope or isomer. 53 Cr is the radiogenic decay product of 53 Mn. Chromium isotopic contents are typically combined with manganese isotopic contents and have found application in isotope geology.
