ionic bonding Flashcards
1
Q
when does ionic bonding occur
A
occurs between metals and non- metals.
2
Q
how do metal atoms form positive ions?
A
lose electrons to form positive ions.
3
Q
how do non-metals form negative ions?
A
tend to gain electrons to form negative ions.
4
Q
what are ionic substances held together by?
A
held together by strong electrostatic forces of attraction between
oppositely charged ions
5
Q
what do ionic compounds form?
A
giant lattices.
6
Q
what type of melting and boiling points do ionic compounds have?
A
high melting and boiling points.
7
Q
why don’t ionic compounds conduct electricity when solid?
A
as the ions are not free to move.
8
Q
when do ionic compounds conduct electricity?
A
when melted or dissolved as ions are free to move
