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
The square of 9 more than a number is equal to 9 more than the square of the number?
The square of 9 more than a number is equal to nine more than the square of a number. What is the number?
What is 4 more than a number?
If the number is represented by X, then '4 more than a number' is represented by (X+4).
What is the Algebraic expression for three more than a number?
The algebraic expression for three more than a number is: X + 3
What is six more than the cube of a number?
If ' N ' is the number, then six more than the cube of the number is (N3 + 6).
Which family has elements that have more than one oxidation number?
transition metals
Can a element have more than one oxidation number?
Yes. Transition metals and halogens other than fluorine are particularly likely to have more than one oxidation number among all their compounds.
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):
How do transition metals properties compare with those of elements farther to the left?
The chemical reactivity of transition metals is generally less than that of metals to its left (group 1 and group 2 metals). However, transition metals can exhibit various oxidation states and hence form more number of compounds than group 1 and group 2 elements.
Which group has more than one positive oxidation state?
The transition metals (groups 3-12) can have more than one positive oxidation state. When you write the names of compounds with transition metals, you note their oxidation state with roman numerals, e.g. iron (II) oxide and iron (III) oxide.
What does the roman numeral tell about an element?
Roman numerals are used to identify the oxidation state of transition metals with more than one possible oxidation state.

Roman Numeral
What happens when a transition metal has more than one oxidation number?
Roman Numeral
What is the oxidation numbers of alkaline metals?
The question should be either 'alkali metals' or 'alkaline earth metals'. For alkali metals or group 1 elements, the oxidation number is +1 (note. hyddrogen can have +1 and -1). For alkaline earth metals, the oxidation number is +2 In addition all these elements will have an oxidation number of 0 in their elemental form
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
Are there more metals or nonmetals?
There are more metals than non-metals. This occurs because of the transition metals group. When looking at a group on the periodic table the transition metals makes up a large portion because they are the atoms that take use of the the d orbital for electrons. The d orbital has room for 10 electrons and therefore there is a large number of transition metals per group.
Why do transition metals share properties with other transition metals in their period?
The physical properties of transition metals are determined by their electron configurations. Most transition metals are hard solids with relatively high melting and boiling points. Differences in properties among transition metals are based on the ability of unpaired d electrons to move into the valence level. The more unpaired electrons in the d sublevel, the greater the hardness and the higher the melting and boiling points.
