Chemistry · Secondary 4 · Hard · Group 1 metals
The melting points of three Group 1 metals are:
- lithium:
- sodium:
- potassium:
What is the trend in melting point down Group 1, and why?
- lithium:
- sodium:
- potassium:
What is the trend in melting point down Group 1, and why?
- Melting point increases because metallic bonds get stronger.
- Melting point decreases because metallic bonds get weaker.
- Melting point increases because atoms get smaller.
- Melting point stays constant because each atom loses one electron.
