WebHowever, manganese in 3d series and Tc in 4d series have low melting point. The maximum melting point at about the middle of transition metal series indicates that d5 configuration is favorable for strong interatomic attraction. The following figure shows the trends in melting points of transition elements. 2. Variation of atomic and ionic size: WebList of elements by boiling point; List of elements by melting point; List of elements by density; List of elements by atomic mass; And here is the periodic table for magnetic resonance. Explanation of the structure of the periodic table [] The number of electron shells an atom has determines to which period it belongs.
