Ionic bonding and compounds Flashcards
(5 cards)
1
Q
What happens when a metal reacts with a non metal?
A
Electrons in the outer shell of the metal are transferred
2
Q
How do metals and non metals become ions?
A
Metals lose electrons to become positively charged ions
Non metals gain electrons to become negatively charged ions
3
Q
How are ionic compounds held together?
A
By strong electrostatic forces of attraction between oppositely charged ions
4
Q
Why do ionic compounds have high melting and boiling points?
A
Because there many strong electrostatic forces of attraction between oppositely charged ions which take a lot of energy (heat) to break
5
Q
Why do ionic compounds conduct electricity when molten or dissolved in water?
A
Because the ions are free to move so charge can flow
