Ionic Bonds Flashcards
1
Q
How do ionic bonds form / what are they?
A
between atoms with a large difference in electronegativity
solid crystals at room temperature with high melting and boiling points
conductors when dissolved in water
2
Q
How are electrons transferred?
A
From low EN to high EN element
3
Q
Electrostatic force
A
positive and negative ion attracted to each other

what ionic bonds form
Repeated continuous arrangement of ions packed together
5
