What is the common oxidation number of cobalt?
Cobalt is a transition metal. Its oxidation states are 2 (3).
What is the change in the oxidation number of Cr?
Cr is a transition metal and has a variation of oxidation number from 0 in the elemental state to +6 in the dichromate ion.
How is the oxidation state of a transition metal determined from the chemical formula?
The subscript of the second ion identifies the oxidation state of the transition metal
How are oxidation states if transition metals indicated in the names of metal compounds?
Roman numerals are used to indicate oxidation states. Apex
What is the difference between late transition metals and early transition metals?
The early vs. late transition metals differ in their oxidation states (each metal has different possible oxidation states). Electrons have a stronger attraction to the protons in the late transition metals, so the later transition metals form bonds that are harder to break. You can read more about transition metal properties from the links below.Source(s):
What is the common oxidation number of cobalt?
Cobalt is a transition metal. Its oxidation states are 2 (3).
Pb is a transition metal with only 1 oxidation state?
No, Pb is not a transition metal and it has 2 oxidation states
When naming a transition metal that has more than one oxidation number the numeric value of the oxidation number is indicated by a?
Roman Numeral
What is the change in the oxidation number of Cr?
Cr is a transition metal and has a variation of oxidation number from 0 in the elemental state to +6 in the dichromate ion.
How does the oxidation state of a transition metal determined from chemical formula?
A pure metal has the oxidation state zero.
What happens when a transition metal has more than one oxidation number?
Roman Numeral
How is the oxidation state of a transition metal determined from the chemical formula?
The subscript of the second ion identifies the oxidation state of the transition metal
What must be use when writing the chemical name for a compound with a transition metal?
When writing the chemical name for a compound with a transition metal, it is important to include the name of the transition metal as well as its oxidation state in Roman numerals. This helps to specify which ion of the transition metal is present in the compound. Additionally, any ligands or other elements in the compound should also be named and included in the chemical name.
What does a transition metal do when it is in its higher oxidation state?
rust
What is the highest oxidation state of transition metal?
Mg
What do Roman Numerals represent in chemistry?
The Roman numeral in the parentheses is the valence or oxidation of the metal that it follows. Transition elements have more than one oxidation number
What is the correct name for compound Cr2O3?
For ionic compounds such as the one mentioned above, naming them is relatively easy. As we all know, an ionic compound consists of a metal ion(which is usually positive) and a negative ion. Hence, the names for metallic compounds are always in the following format: Name of metal + Name of negative ion However, do take note that for transition metals, the oxidation state has to be included. This is because transition metals have multiple oxidation states. The oxidation state of the metal is presented by: Metal (oxidation number). For example, rust is Iron (III) oxide. Cr2O3 is hence named chromium (III) oxide.
