Pick any transition metal or any poor metal except aluminium, and you'll have your answer. The poor metals are aluminum (Al), gallium (Ga), indium (In), tin (Sn), thallium (Th), lead (Pb) and bismuth (Bi). All other metals in Group 3 through Group 12 metals which are between the Alkaline Earth metals and those poor metals (except aluminium) have multiple oxidation numbers. Need a link to a good Periodic Table of the elements? Got one for you. It's got it all, and each element on the table is a hyperlink to a post about that particular element. Bookmark this puppy and learn how to use it. Please. It'll take you through high school chemistry and into college chemistry with no trouble at all.

Do transitionn metals have a consistent oxidation number?
transition metals have variable oxidation states
Why transition metals have variable oxidation number?
Transition metals have variable oxidation numbers because they have incompletely filled d orbitals in their outermost electronic shell. These d orbitals can participate in bonding and easily change their oxidation states by gaining or losing electrons. This flexibility allows transition metals to exhibit a wide range of oxidation states in different compounds.
What group has variable oxidation numbers?
Groups 1 and 2 are +1 and +2 respectivelly.. Group 3-12 have variable oxidation numbers - they are the so-called transition metals. Group 14-17 have variable oxidation numbers -even group 18- has- there are a number of different compounds of Xe for example. Group 1 and 2 have some strange compounds such as Cs11O3 . A better question might be which group doesn't have variable oxidation numbers!
Explain how arrangemant of the iron traid difers from arrangement of coinage metals?
The iron triad has the most variable oxidation states from +6. Coinage metals have oxidation states of +1 except for copper(+2)
Do metals have more than one oxidation number?
Yes, some metals can exhibit multiple oxidation numbers due to the ability to lose electrons from different orbitals. These variable oxidation states arise from the different ways in which the electrons in the outermost energy levels can be lost.
Why do transition metals have variable oxidation states?
Transition metals can move electrons between the outer shell and the d d orbital. For example, copper can either lose its 2 s electrons or move one of those s electrons into d orbital, which is one electron short of being full.
How do you assign charges to transition metals?
Transition metals can have variable oxidation states, so charges are determined based on the overall charge of the compound or complex. The charge on the metal is often calculated by considering the charges on the ligands and balancing them with the overall charge on the compound. Oxidation state rules and knowledge of common oxidation states for transition metals can also help assign charges.
What is the oxidation number of non metals?
The oxidation number of non-metals can vary depending on the element and the compound it is in. Generally, non-metals tend to have negative oxidation numbers when they form compounds with metals, but they can also have positive oxidation numbers when they form compounds with other non-metals.
What are the oxidation numbers for the metal groups 1A 2A 3A?
Group 1 or alkali metals (+1 oxidation number). Group 2 or alkaline earth metals (+2 oxidation number).
Do all metals have two oxidation numbers?
No, not all metals have two oxidation numbers. Some metals may have multiple oxidation numbers depending on the bonding situation and the compounds they form.
Metals that are less reactive that aklitlsnd alkaline earth-metals are called?
Metals that are less reactive than alkali and alkaline earth metals are called transition metals. They are typically less prone to reacting with other elements and have distinctive properties such as variable oxidation states and the ability to form colored compounds.
What is oxidation number of transition elements?
The oxidation number of transition elements can vary because they have multiple oxidation states. Transition metals typically exhibit more than one oxidation state due to the presence of partially filled d orbitals, allowing them to lose a variable number of electrons. Common oxidation states for transition elements range from +1 to +7.
