Its a good idea to have some idea of where the metallic elements are in the periodic table

The black zig–zag line 'roughly' divides the metals on the left from the non–metals on the right of the elements of the Periodic Table.

Pd metals Part of the modern Periodic Table Pd = period, Gp = group metals => non–metals Gp1 Gp2 Gp3 Gp4 Gp5 Gp6 Gp7 Gp0 1 1H  Note that H does not readily fit into any group 2He 2 3Li 4Be atomic number Chemical Symbol eg 4Be 5B 6C 7N 8O 9F 10Ne 3 11Na 12Mg 13Al 14Si 15P 16S 17Cl 18Ar 4 19K 20Ca 21Sc 22Ti 23V 24Cr 25Mn 26Fe 27Co 28Ni 29Cu 30Zn 31Ga 32Ge 33As 34Se 35Br 36Kr 5 37Rb 38Sr 39Y 40Zr 41Nb 42Mo 43Tc 44Ru 45Rh 46Pd 47Ag 48Cd 49In 50Sn 51Sb 52Te 53I 54Xe 6 55Cs 56Ba Transition Metals 81Tl 82Pb 83Bi 84Po 85At 86Rn Gp 1 Alkali Metals  Gp 2 Alkaline Earth Metals  Gp 7 Halogens  Gp 0 Noble Gases Chemical bonding comments about the selected elements highlighted in white e.g. the 'white' highlighted elements are typical metals you are likely to have come across, either as a pure metal or in an alloy mixture of metals – all the atoms are held together by what is called 'metallic bonding' – details of the bonding model below

Metallic bonding is described and the properties of pure metals and alloys are described and explained using the giant metal lattice structure model which is used to explain the physical properties of metals.

The structure of alloys is explained and why alloy metals are more useful than pure metals.
