How to answer questions about…
Formation of ionic compounds:
- list the electron configuration
- electron valence
- needs to gain/lose electron to form an octet structure
- atom will donate/take electrons to form an octet structure
- valence electron of atom is X, so atom needs to gain/lose electrons to form an octet structure
- when Y atom loses/gains X electrons, it will form an ion in the charge of +/- X (Repeat for other element)
- the + ion and the – ion charge are attracted to each other and form an electrostatic forces
- this will form an ionic bond between ions and form Z (name the compound)
- draw the diagram
e.g.
e.g.
Formation of covalent compounds:
- list the electron configuration
- each X atom needs Y electrons to form an octet structure
- non-metal – each X atom will share Y pair of electrons with another X atom
- this will form a Van der Waals’ force and later a single/double covalent bond
- draw the diagram
