What kind of bond is formed when electrons are donate/receive from one atom to another?
Ionic bond
What type of elements usually form ionic bonds?
Metal and non-metal
Why do atoms form ionic bonds?
To achieve a stable duplet/octet electron arrangement
State one physical property of an ionic compound.
High melting and boiling point / conducts electricity in molten or aqueous state
What kind of bond is formed when atoms share electrons?
Covalent bond
Which type of elements usually form covalent bonds?
Non-metal with non-metal
Give one example of a covalent compound.
O₂, CO₂, Water (H₂O), Carbon dioxide (CO₂), Methane (CH₄)
Can covalent compounds conduct electricity?
Cannot (because they do not have free-moving ions or electrons)
Which type of compound dissolves better in water – ionic or covalent?
Ionic
What is the bond called between a hydrogen atom and an electronegative atom like oxygen or nitrogen?
Hydrogen bond
Give one example of a substance where hydrogen bonding occurs.
Water (H₂O), ammonia (NH₃)
What kind of bond is formed when both electrons in a shared pair come from the same atom?
Dative bond
What type of bond involves a 'sea of delocalized electrons'
Metallic bond
