Number of elements having more melting point than Be
Na, Li, Mg, Ba, Sr, K, Rb, Ca, Cs
Answer:
0
Solution:
Be > Mg > Ca > Sr > Ba
Be has the highest melting point among the given s-block elements because its atoms are very small and show strong metallic bonding.
Alkali metals (Li, Na, K, Rb, Cs) have much lower melting points due to weaker metallic bonds.
Hence, no given element has a melting point greater than Be.
The final answer is .
