(a) Magnesium (Mg) (b) Nickel (Ni) (c) Palladium (Pd) (d) Tungsten (W)

Work Step by Step

The identity of an element is given by its atomic number; therefore, we just have to determine them in each case and use a periodic table to get the correct answer. ** The atomic number (Z) is the bottom left number of the symbol. (a) Z = 12; Magnesium (Mg) (b) Z = 28; Nickel (Ni) (c) Z = 46; Palladium (Pd) (d) Z = 74; Tungsten (W)
