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.

How do you calculate valency of an element?
The number of valence electrons is easily found. You can take a look at the periodic table, ignore the transistion metals and count. The first column has one valence electron, the second column has two and so on. The noble gases have eight--which makes sense because they tend to be chemically stable (fulfilling the octet rule).
How do you calculate the valency of an element from its electronic configuration?
To calculate the valency of an element from its electronic configuration, determine the number of electrons in the outermost shell. The valency is typically the number of electrons needed to complete the outermost shell to achieve a stable octet (eight electrons). For example, elements in group 1 have a valency of 1, while elements in group 17 have a valency of 7.
Why is the valency of chlorine one?
Chlorine has a valency of one because it has seven valence electrons in its outer shell. By gaining one electron, chlorine can achieve a stable electron configuration similar to that of a noble gas, specifically argon, which has a full outer shell with eight electrons.
Most metals and nonmetals bond together to get eight electrons in their outer occupied shell?
Most metals and nonmetals form chemical bonds by transferring electrons to achieve a stable electron configuration with a filled outer shell, usually with 8 electrons. This transfer of electrons leads to the formation of ionic bonds between metals and nonmetals.
Why is the valency of oxygen 2 instead of 6?
The valency of an element indicates the way it will react in a chemical reaction. For example, oxygen has six outer electrons and only needs eight electrons to have a complete outer shell. It can either lose six electrons or gain two electrons. It is easier for an oxygen atom to gain two more electrons and therefore its valency is 2.

What are theSections of the periodic table?
There are eight classifications of elements in the periodic table. They are: Non-metals, transition metals, rare earth metals, halogens, alkali metals, alkali earth metals, other metals and inert elements.

Why scandium has valency of 3 whereas its outer shell has only two electrons?
scandium belongs to 3d series and in scandium in addition to 2 electrons in 4s one electron of 3d subshell also takes part in bonding so its valency is three despite of only two electrons in outer shell. remember valency is no. of electrons taking part in bonding
