Group 2 Flashcards
1
Q
why strontium has a higher melting point than barium?
A
the larger the ions within the metallic structure, the weaker the attractive forces as the attractive force has to act over a much greater distance. Therefore the melting points decrease down the group.
2
Q
use of magnesium hydroxide in medicine?
A
- relief digestions as it is used as an antacid and can neutralize acids.
