What 3 properties of transition metals?
Good conductors of heatGood conductors of electricityDuctileMalleableUnreactive but form alloysHigh melting points (except mercury)High boiling points (except mercury)
Properties of transition metals?
They often form colored compounds.They can have a variety of different oxidation states.At least one of their compounds has an incomplete d-electron subshell.They are often good catalysts.They are silvery-blue at room temperature (except copper and gold).They are solids at room temperature (except mercury).They form complex ions (aqua ions included).They are often paramagnetic.
What are some metallic properties?
high melting and boiling point, good conductor of electricity and heat, solid at room temperature (except mercury)
Do non-metals have a high boiling point?
Not really, most have low boiling points, except for carbon, for example, which has one of the highest boiling points of any substance at 4827 ºC and Silicon boils at 2355 ºC. Iodine boils at a higher temperature than mercury.
What is description of helium?
Helium is a chemical element with symbol He and atomic number 2. It is a colourless, odorless, tasteless, non-toxic, inert, mono-atomic gas that heads the noble gas group in the periodic table. Its boiling and melting points are the lowest among the elements and it exists only as a gas except in extreme conditions.

Properties of transition elements at room tempertature?
Transition elements are ALL solid metals except for mercury (80Hg) which is a liquid.
What are representative elemets?
The elements in the first two groups and in the last 6 groups. Basically all the elements except the inner transition and transition elements.
What are the melting and boiling points of different substances?
At 1atm, the melting point of H2O(water) is 0 degrees celcius and the boiling point is 100 degrees celcius. Carbon dioxide's boiling point is at -25 degrees and so its meting point. Since it crystallises and sublimates, it has no liquid form. The boiling- and melting points of elements/compounds depend on the amount of pressure exerted on the element/compound. Generally, the higher the pressure, the higher the boiling and melting points. All except for water, gallium and bismuth. These substances' melting point decreases as pressure increases.

What is H.E.?
HE is a nother writin form of helium.Its a colorless, odorless, tasteless, non-toxic, inert monatomic chemical element that heads the noble gas group in the Periodic Table and whose atomic number is 2. Its boiling and melting points are the lowest among the elements and it exists only as a gas except in extreme conditions.
Is copper a alkali or a transition metal?
Alkali metals are found only in the first family (column) in the periodic table.Copper is a transition metal.This site is GREAT for learning all about specific elements and their properties. It's basically a periodic table of elements, except the elements have all been linked to pages that have a pretty decent amount of information on each.http://www.ptable.com/
Exactly which elements form multiple ions?
All of the transition metals are capable of forming multiple ions except for Zn, Cd and Ag.
Name two characteristics of the elements in the first group?
Elements in the first group of the periodic table, also known as Group 1 or the alkali metals, are highly reactive due to their single valence electron. They are soft metals that can be easily cut with a knife and have low melting and boiling points compared to other metals.
All of these elements point to the need for nevadas rapid transition except?
Such rapid transitions may seem all the more remarkable to someone who has spent months.
