The atomic number(原子序数)is equal to the number of electrons per atom or, what is equivalent, the number of protons per nucleus(原子核).
The term atomic number , conventionally denoted by the symbol Z , indicates number of protons present in the nucleus of an atom, which is also equal to the number of electrons in an uncharged atom. The number of neutrons is represented by the neutron number ( N ). Because the mass of ...
The correct Answer is:B, C To determine the number of d-electrons in Mn2+ and find which element has the same number of d-electrons, we can follow these steps: Step 1: Determine the atomic number of manganese (Mn)Manganese has an atomic number of 25. This means a neutral manganese at...
nucleus. Accordingly, the number ofprotons, which is always equal to the number ofelectronsin the neutral atom, is also the atomic number. Anatomofironhas 26 protons in its nucleus; therefore, the atomic number of iron is 26 and its ranking on the periodic table of chemical elements is 26...
