What is the trend in melting points among alkali metals as you move down the periodic table?
Options
- AMelting points decrease
- BMelting points increase
- CMelting points remain constant
- DMelting points are unpredictable
Correct answer
A. Melting points decrease
Step-by-step solution
The melting points of alkali metals generally decrease as you move down the periodic table, which is a consequence of weaker metallic bonding due to the increased atomic size and greater distance between the valence electrons and the nucleus.
