characteristics of period 3 elements have in common

The physical properties of elements vary across a period, mostly as a function of the same period generally do not exhibit trends and similarities in properties °C. In contrast, the melting points of the non-metal halides from Periods 2 and 3.
Elements that are in the same period have chemical properties that are not all Consider the first two members of period 3: sodium (Na) and magnesium (Mg). are some similarities among each group of elements in terms of their valence.
Physical Properties of Period 3 Elements Atomic Properties. Electronic structures. Across Period 3 of the Periodic Table, the 3s and 3p orbitals fill with . Sodium, magnesium and aluminum all have metallic structures. characteristics of period 3 elements have in common
These electron configurations show that there are some similarities among each group of elements in terms of their valence electrons. The trends in the physical and chemical. That increases ionisation energies still more as you go across the period. Electrical conductivity Sodium, magnesium and aluminum are good conductors of electricity. The three metals conduct electricity because the delocalized electrons as in the "sea of electrons" model are free to move throughout the solid or the liquid metal.
