N5 Topic 3 - 3.1 - Ionic Bonding Flashcards
What is an IONIC BOND?
It is an electrostatic force of attraction between positivley charged ions and negativley charged ions.
Do ionic bonds have high melting/boiling points or low melting/boiling points? Explain your answer
They have high melting/boiling points because they are really strong.
What is the name of two ions that have transferred electrons and are held together by ionic bonds?
What does Valency mean?
It is the number of electrons needed to lose or gain to become stable
All —— lose —– to become positive ions
All metals lose electrons to become positive ions
—— gain electrons to become —- ions
Non-Metals gain electrons to become negative ions
Ionic bonding needs to have….
a metal and a non-metal
Do most ions have colour?
No, they are colourless. When they are in a solid compound, they appear white.
When do ionic substances conduct electricity?
They only conduct electricity in solution or molten (liquid)
Why can ionic solutions conduct electricity?
The solutions formed can conduct electricity because the ions are able to move freely
