What property do the following elements have in common? Li, C, and F A) They are poor conductors of electricity. B) Each element
participates in covalent bonding. C) They all exist in the same phase at room temperature. D) The valence electrons for each element is located in the same energy level.
The given elements Li, C and F are all second period elements. So, when we move from left to right across a period then there occurs increase in number of valence electrons as there occurs increase in total number of electrons.
So, it means more electrons are added to the same energy level.
Thus, we can conclude that a property of valence electrons for each element is located in the same energy level is common in the given elements.
Toasting in a toaster is usually considered by (infra red) radiation. But the hot coils touch the toast so an element of heating by conduction occurs as well.
