Unit 9B- Recall Questions- Ionic And Mettalic Bonding Flashcards
How are positive ions formed?
Through the loss of electrons
How are negative ions formed?
Through the gain of electrons
In which groups of the periodic table do atoms form positive ions
Groups 1, 2, 3 (they lose electrons from their outer shell)
In which groups of the periodic table do atoms form negative ions?
Groups 5, 6, 7 (they gain electrons to fill their outer shell)
Between which elements does ionic bonding occur?
Metals and non-metals
How are ‘ionic bonds’ formed?
Through the transfer of electrons between atoms
What are ‘ionic bonds’ otherwise known as?
Electrostatic forces (between oppositely charged ions)
Describe the structure of a solid ionic compound.
Lattice structure - regular arrangement of ions held together by strong electrostatic bonds between ions
When two substances bond through ionic bonding, what does the name of the compound usually end in?
-ide
What does it mean if the name of a compound ends in -ate?
It contains oxygen in addition to the other elements
Describe the structure of metals.
Positive ions (cations) held together by a ‘sea’ of delocalised electrons
