$4$ Part $4$: Feature Calculation

Given below is a dictionary containing physical properties of the elements in the current composition space. Using this information, add columns to your data frame with the weighted average:

valence electron concentration $($VEC$,$ electron$/$atom$)$

Melting Point $($MP$,$ celsius, based on experimental data of most stable phase at standard temperature$)$

Bulk Modulus $($B$,$ GPa, calculated from first principles $($DFT$)$ for bcc phase$)$
