What is ionic bonding?
The transfer of electrons between atoms, forming (+) and (-) ions that are held together by electrostatic attraction.
How are ions formed in ionic bonding?
When atoms lose or gain electrons to achieve a full outer shell.
Ionic is between what?
Metals and non- metals.
Explain the transfer of electrons in ionic bonding?
Metals always lose (e-) to form positive ions, non-metals always gain (e-) to form negative ions.
Ionic compounds always make...
Salts
Give an example of an ionic compound
NaCl
Describe an ionic bond
Strong electrostatic attraction between oppositely charged ions
Properties of ionic compounds
High melting and boiling points, conduct electricity when molten or dissolved in water
Describe the structure of the ionic compoundNaCl
Crystalline solids with a regular lattice structure
Why do ionic compounds have a high melting point?
They have a giant lattice structure and are held together by sea boci therefore requiring large amounts of energy to break them.
What's the difference between giant and regular lattice?
Giant- high melting point and hardness/strength. For example diamond.
Regular- lower melting point and weaker. For example sodium chloride.
Why do ionic compounds conduct electricity when molten or dissolved in water?
Because the ions are free to move and carry charge.
