Bonding Flashcards
What are the 2 main types of bonds found in compounds?
Covalent & ionic
Where are covalent bonds found?
In non metal compounds
Where are ionic bonds found?
Between metals and non metals
When do covalent bonds form?
When atoms share electrons to achieve an electron arrangement like a noble gas
When do ionic bonds form?
When metal elements lose electrons to achieve a stable electron arrangement
When metal elements lose electrons, what gains them?
Non metal elements
What do ionic substances make?
Lattices
Describe the properties of lattices
They have:
• high melting and boiling points
• good solubility in water
• ability to conduct electricity when molten or in solution
Why do lattices have high melting points?
Because strong ionic bonds must be broken to break up the lattice
What do covalent substances make?
Molecules or networks
Describe the properties of molecules
They are small bundles of atoms covalently bonded together. These have: • low melting and boiling points • poor solubility in water • no electrical conductivity
Describe the properties of networks
They are giant structure containing billions of atoms covalently bonded These have: • high melting and boiling points • poor solubility in water • no electrical conductivity
