S4 Flashcards
What are ionic bonds formed by?
Ionic bonds are formed by the transfer of electrons between atoms of metals and non-metals.
What do ionic bonds form?
Ionic bonds form ions, which are charged particles.
What happens to ions of opposite charge?
Ions of opposite charge attract each other, forming the bond.
What happens to sodium (Na) in ionic bonding?
Sodium (Na) gives up an electron, becoming a + ion with more protons than electrons.
What happens to chlorine (Cl) in ionic bonding?
Chlorine (Cl) takes in an extra electron, becoming a - ion with more electrons than protons.
What are the properties of ionic bonds?
Ionic bonds form solids at room temperature and are organized in a characteristic lattice of alternating positive and negative ions.
What is the nature of the reaction in ionic bonding?
Ionic bonding is always exothermic.
What are the melting and boiling points of ionic compounds?
Ionic compounds have high melting and boiling points.
How do ionic compounds behave in water?
Ionic compounds dissolve in water.
Does Na show ionic or covalent bonding?
Na shows ionic bonding.
