Question #2eafd
2 Answers
aluminium(Al)
Explanation:
this because aluminium has got three valence electrons in the outermost energy level hence has a stronger metallic bond/character than beryllium(Be) which has two valence electrons
Beryllium.
Explanation:
We can compare the metallic character of the two elements with reference to their electronegativity- both characteristics are related to an atom's ability to attract electrons in a compound.
Referring to the Pauling Scale of electronegativity values, we see that aluminum has an electronegativity value of
