NEED HELP ASP DONT WANNA MISS MYF RIENDS BIRTHDAY PARTY Of the following compounds: 1. gold 2. mercury 3. Ag 4. W 5. Li 6. Be 7. nickel 8. oxygen When involved in an ionic compound the elements which have multiple charges and therefore must be indicated in Roman numerals (in ascending order) are: (Example: metal (V) non- metal)

The elements that can have multiple charges are;

1. Gold; gold (I) gold (III),

2. Mercury; mercury (I) mercury (II)

3. Ag; silver (I) silver (II) silver (III)

4. W; tungsten 0, tungsten (I)... tungsten (VI)

5. nickel, nickel 0 nickel (I)... nickel (IV)

Explanation:

Transition metals are the 38 elements that have partially filled or can form partially filled d-orbitals. Elements of the transition metals can have multiple oxidation states by having more than one ionic state which thus requires the specification of the ionic state in a compound by Roman numerals such as Fe²⁺ and Fe³⁺ specified as iron (II) and iron (III) respectively

Elements included as transition metals includes, nickel, Ni, tungsten, W, Silver, Ag, Gold, Au, Mercury, Hg.
