Question

in each of the following pairs identify which element is more metallic (beryllium Boron)
​

Answer 1

Answer:

Be

Explanation:

metallic character decreases as we move across the period from left to right, because the atoms more readily accept the electrons to fill their valence shell, than lose an electron in order to remove the unfilled shell.Therefore Be (beryllium) is more metallic than B (boron).

Answer 2

Explanation:

• Beryllium (Be) and Boron (B) belong to the 2nd period in the periodic table.
• Beryllium is more metallic than the Boron as it comes before Boron in the periodic table.
• And metallic character decreases as we move across the period left to right.
• Because the atoms more readily accept the electrons and fill their vacant shell than lose an electron to remove the unfilled shell.
