what are the six noble gases i want  to know?

helium neon argon krypton xenon radon\nyou probably do not need to know ununoctium because it was just discovered, is radioactive, and radioactively decays in a few seconds.

Solid or gaseous, depending on what the question means when refering to non-metals:  There are 11 gases total out of the entire table (6 are nobel gases) and only 2 liquids..mercury and bromine.  The true non-metals comprise only 7 elements, and only 3 of those (hydrogen, nitrogen, and oxygen) are gases.  If you takea  looser definition of non-metals, which includes the true nonmetals plus the halogens and noble gases, the the answer is gaseous.  From the wording of the question, I would think they were trying to get you to say gaseous.

Noble gases are also called inert gases because they do not react chemically.  There the one in the last column of the table.  Their last electron layer is full (all 8 electrons --2 for helium-- are there) and that's why they don't (usually) form bonds.

Do you mean what where are the d sublevels? If you do they are the transition metals.  But i do not think that is your question. Do you mean the fourth row? That would be the latest last noble gas configuration then s2 of next level up then d2 of same level of last noble gas. I hope it helped. Maybe you should clarify your question.

It´s 10. Neon. \nIt has two energy levels, filled with 2 and 8 electrons respectively.

The platinum group or platinum metals is the collective name sometimes used for six chemical elements within the periodic table. These elements are all transition metals, lying in the d-block (groups 8, 9, and 10, periods 5 and 6 - in Mendeleev's original table, this area was called "Group VIII").\n\nThe six platinum metals are: ruthenium, rhodium, palladium, osmium, iridium, and platinum. They have similar physical and chemical properties, and tend to occur together in the same mineral deposits.

Um, there's over a hundred elements.  I'm not going to name them all for you.  Look at a periodic table.  I'm sure there's one in your chemistry book.

All atoms do this. The Noble gasses have the most stable electron configurations because they fill/do not have "open shells".\n\nFor example, Calcium's nearest noble gas is behind it, so it will LOOSE two electrons, since losing two is easier than gaining 6 to act like the next noble gas ahead of it, that's why you see Calcium as a 2+ ion. (Ca2+). Iodine, on the other hand needs to gain one electron (instead of losing 7) to be like it's nearest noble gas, so you get the ion of I-. For a metal like silver, it just has one "valance" electron, so you'll see silver as Ag+. Copper has two extra : Cu2+, Iron typically has 3 valance electrons so it make Fe3+

Noble gases are inactive\nhalogens are very active\nLast one, ionization energy decreases\nlanthanide and actinide are the bottom 2 periods

Do a search for the isotopes of gold.  The list should give you each of the isotopes with its "mass number" (there are about 35 isotopes beginning with Au-172 and going through Au-205. ) The mass number is the total number of protons + neutrons.  Since gold is element #79 all of its isotopes have 79 protons so just subtract 79 from the mass numbers to get the neutrons.  Assuming we are talking about neutral gold atoms, the electrons = protons = 79.

2 KBrO3 + 3 N2H4 -> 2 KBr + 3 N2 + 6 H2O\n\nYou can check by finding out the total number of atoms of both sides:\n 2 Potassium\n 2 Bromine\n 6 Oxygen\n 6 Nitrogen\n12 Hydrogen

argon(Ar):1s2,2s2,2p6,3s2,3p6 is a noble or inert gas and has completely filled 3s and 3p orbitals.due to this it has a very high ionisation potential which means it is very difficult for it  lose electrons and react with other elements.it also cannot form any covalent bonds.thus argon shows no chemical properties for it dosent react at all. only Xenon(also a noble gas) shows chemical properties by reacting with flourine
