What polyatomic anion contains Hydrogen, Carbon and Oxygen and also contains the cation Neon?

The only thing I can think of is a fullerene cage that is trapping the Neon...hmmm\nIf you were thinking Nitrogen...try any amino acid ...umm adesonine (if thats how its spelt)

oxygen, nitrogen, hydrogen, methane, helium

Na+ and K+ (both group 1)\nCa2+ and Mg2+ (both group 2).\nNa+ and Mg2+ have the electron arrangement of neon, and the other two that of argon.\nIonic radius decreases from left to right, and increases top to bottom, so K+ is the largest of all these.\nElectronegativity increases upwards and to the right of the Periodic Table, so Mg has the highest value of these four.

Look at the periodic table. Number 1 hydrogen has 1 proton and 1 electron. Number 2 helium has 2 protons, 2 electrons and 2 neutrons.

Four as a stable compound, up to 5 or 6 for a polyatomic ion.

1)   O::C::O  for CO2 because there are total 4 valence electrons in outermost orbit of carbon so it will share 2 with each oxygen and it has 3 resonance structures\n\n2)  H . . C three electrons shared from carbon and nitrogen N\nie on one side one electron sharing by hydrogen and carbon and on other side 3-3 electrons shared by both carbon and nitrogen\n\ni hope it helps you out

dioxygen is the most common molecule that contains oxygen.  \ncarbon dioxyde, for example has two oxygens and one carbon molecule.

Made up of two glucose isomers.\n\nEntirely carbon, oxygen and hydrogen

This question could have several answers, depending on the meaning of life and the quantity of atoms.  If human life is the question then the answer, by weight, is Oxygen, Carbon, Hydrogen, Nitrogen, Calcium,        Phosphorous, Potassium, Sulfur, Sodium, and         Chlorine.

Mostly hydrogen. There is a little bit of helium and heavier elements in there as well.

helium,.........,hydrogen,............, and oxygen??? I don't have the book on me right now, so I am drawing a blnk

Unable to guesstimate.  You're talking biological macromolecules, most likely.  They would probably have carbon, hydrogen, nitrogen, oxygen, sulfur, phosphorus, and perhals a halogen or two.  And maybe even a metal ion or two thrown in for good measure.

Baking soda's chemically known as sodium bicarbonate, so it contains sodium (obviously) as well as hydrogen, carbon, and oxygen (that's the bicarbonate part).

Franpal is correct, hydrogen and oxygen.  If you're thinking of a D, it may be 'heavy water', which has Deuterium rather than hydrogen (an isotope of hydrogen).

As an ion, oxygen is negative.  As a molecule, 02 is neutral.  \nAn an ion, hydrogen is positive.  As a moleclue, H2 is neutral.
