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 many valence electron's is in xenon?
Eight: the valency shell is full.
Most metals and nonmetals bond together to get eight electrons in their outer occupied shell?
Most metals and non-metals bond together to get eight electrons in their outer occupied shell. This is what is referred to as ionic bonding.
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.
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).
What type of structure does sodium possess?
Sodium in its elemental form is a metal. The crystal structure of the metal lattice is body centred cubic where each atom has eight near neighbours. This structure is adopted by all of the group 1 metals.

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.
What is an eight letter word that means a variable that does not change in an experiment?
controls
How do you find a valence number?
if the no of atoms in the last shell is less than four,write the no of atoms down. if it is more than four,subtract the no from eight. the no is the valency

How can thirteen be half of eight?
It can't be unless a variable is included in the equation.

What is eight less than a number x is at least 17?
It is an inequality in the single variable, x.

It is x/3 - 8
