Where do the charges on polyatomic ions come from eg for the Hydroxide ion does that mean that the oxygen has picked up an additional electron from somewhere and has 7 electrons?

No ion of any type can exist in isolation - positive or negative - there are always partners - one gains and one looses electron(s). The oxygen in the hydroxide ion has 8 electrons, not 7 - 6 from the O, 1 from the H and one that gives it the -ve charge.

Why do electrons emit light when they fall down to their ground state?
There's a difference in energy between the excited state and the ground state. The energy has to go somewhere. It's generally emitted as electromagnetic radiation ... "light".
What does the nucleus of copper look like?
The nucleus of copper consist of Protons and Nuetrons. Which make up the bulk of the mass of copper with nuetrons being slightly larger than protons. In the electron cloud surrounding the nucleus commonly depicted as rings are where the electrons are located. In a regular copper atom you will find 29 protons, 29 electrons, and somewhere in between 28-30 nuetrons depending on the isotope.
What are the locations of the subatomic particles in an atom?
Neutrons and protons are bound together in the nucleus at the center of the atom; electrons occupy various orbitals or energy levels outside and around the nucleus. Neutrons are neutral or have no charge, protons have a positive charge; electrons a negative charge.
How many electrons are there in the universe?
Most astronomers estimate the number at somewhere between 1070 and 1090.
In the atom where are electrons found?
The electrons in the atom are found on the outer rings, the limit of 2 on the first up to 8 on the valence ring. The number of the electrons found on the valence ring determines where the chemical is placed on the Periodic Table.
Is it possible for an atom to have a negative charge or a positive charge?
Yes, an atom can take on additional electrons to fill its outer shell, becoming a negatively charged ion (called an anion). These electrons have to come from somewhere, so another gave away the same number of electrons (or possibly if two electrons were involved for example, then two atoms could each give up 1 electron). The atom which gives up its electron is a positively charged ion (called a cation)
How many electrons would fit in the universe?
somewhere around 4*10^184 planck cubes could fit in the obervable universe and those are a lot smaller than electrons. So that number would be somewhere between a googol and this number.
If an atom has fewer than 4 electrons in its outer shell does it looses electrons gain electrons or both?
The atom wants to have eight or full electrons in its outer valence ring... so if it has four electrons in its outer shell it has the choice of loosing four electrons or finding four electrons somewhere else (whichever is the easiest for it to bond with).
What is the amount of electrons in gold?
I believe 79. I don't really remember, but I think it was somewhere around there.
How many electrons does an atom need for the outer rings to be complete full?
i think the answer is 8 electrons...idk if tht is right so look it up somewhere else
Why the current is reduced as electrons move through a conductor?
I assume you are referring to electrical resistance. Basically, some electrons in a current will collide with atoms or other electrons, and lose energy in the process. This energy, of course, has to come from somewhere - so the current loses energy.
What must you do to convert a 96 cubic in to a 110 cubic in?
You must send someone to find an additional 14 cubic in somewhere.
What kind of charge can move from object to object?
Electrons can move from object to object. Electrons have a negative charge. So if an object is determined to have a positive charge, then some of the electrons have moved from the object to somewhere else. Something with a neutral charge has the same number of electrons [-] and protons [+]. If electrons [-] leave, then there will be more protons, and a net positive charge. If an object gains electrons, then the object has a net negative charge.
Is hydroxide a liquid?
The term hydroxide is generally used to refer to an ion and not a "substance" per se. In that light, hydroxide cannot be a solid, liquid or gas as we think of atoms or molecules. The hydroxide ion is a bonded pair of atoms, one of oxygen and one of hydrogen. It has the chemical symbol OH- because this ion "came from somewhere" with a "partner" ion that a "+" charge on it. The ions, because they are in a situation where they've become separated from each other, are not generally considered using the term "liquid" when we look at them (even though they may be in liquid solution).
What is the atomic mass of a electron?
That's going to be somewhere in the neighborhood of 0.00054 . About 1,840 electrons have the same mass as one neutron or proton. So, in the largest naturally occuring atom ... Uranium ... with 92 electrons, the electrons don't even contribute 1 count to the mass of the whole atom.
What is the function of sodium hydroxide?
In? Its not in anything if its just NaOH... could be in a container?... or stored somewhere... its not always physically in something. i guess the Na cation would be in the OH anion... but no. its not in anything...
What can you mix with iodine crystals to make it combust into a cloud of reddish smoke?
You can add the iodine crystals to Ammonium hydroxide to form a paste that will explode into reddish smoke when aggrivated. I read somewhere that a few drops of Turpentine will produce a similar result.
