Ionic Bonding Flashcards
1
Q
What is ionic bonding?
A
When an atom gains or loses an electron to or from another atom to form charged ion particles which are then strongly attracted to one another.
2
Q
What is an ion?
A
A charged atom or molecule.
3
Q
When an atom gains or loses an electron it forms…
A
Ions
4
Q
Metals lose electrons to form ________ ions.
A
Positive
5
Q
Non-metals gain electrons to form ________ ions.
A
Negative
6
Q
Why does an Na+ ion latch onto and react with a Cl- ion
A
The ions are oppositely charged and so they’re attracted to each other.
7
Q
What structure do ionic compounds have?
A
Giant ionic lattices
8
Q
Name three properties of an ionic lattice structure?
A
Any 3 of the below:
- High melting points (strong attraction)
- High boiling points (strong attraction)
- Melt = ions free to move and carry electric current
- Soluble in water, free to move in solution and carry electric current
