An atom that is considered a "good" electron needs to have an available energy level that is lower than the energy of a valence electron of a different atom. An atom that is considered a "poor" electron will have the valence electrons be at a higher energy than other atoms. Given this, consider rows 2 and 5 in the periodic table. Why should fluorine, in row 2, be more reactive than iodine, in row 5, while lithium, in row 2, is less reactive than rubidium, in row 5?
Which of these statements is incorrect about electrons?
O Electrons are found in the nucleus of atoms.
O Electrons are negatively charged.
O Electrons repel other electrons.
O Electrons attract protons.
(a) Using the periodic table provided, write down the shorthand electron notation for the following three
elements and indicate whether they are active, inactive or intermediate:
Scandium (Sc):
Argon (Ar); Aluminium (Al)
(b) Metals are conductors of electricity whereas insulators such as ceramic materials are not. Using the
honding theory, show and explain why metals are conductors and ceramics are insulators.
(c) Aluminium is a good conductor of electricity. A 100 m aluminium wire of diameter 2.25 mm is to be
used in domestic electrical wiring. If a voltage of 250V and a current of 13 amps are needed,
answer the following
i.
What is the conductivity of the aluminium wire?
ii.
Give two reasons why aluminium wire is not used in domestic wiring in Zambia?
ii.
Give three applications of pure aluminium.
