What are the charges and relative masses ofthe three subatomic particles that are of most interest to chemists
155512
not being a chemist, I'm not sure I know which 3, but I'm making an educated guess that the answer is protons, neutrons and electrons. If I remember correctly:\nprotons have a charge of +1 and a mass of 1\nelectrons have a charge of -1 and so very little mass that generally, they are considered to have a mass of 0.\nneutrons have no charge, and have a mass of 1

It depends on how far away from the noble gases they are. Like anything in gourp IA would be 1+, IIA 2+ etc, then when theyre closer to the right then its like VIIA 1-, VIA 2-\n\nTransition metals are different because they form multiple ions. It would indicate what the charge is.

The 3 protons are equal in mass, charge and charge polarity i.e., (+)ve (.)\n\nso, they will repel each other by equal force which can be denoted by arrow directed away from each other and thus in steady state they will occupy one vertex each of an equilateral triangle.

For the groups on the table, the ion charges are\n\n          1       +1\n          2       +2\n         13      +3\n         14    +4/-4\n         15       -3\n         16       -2\n         17       -1\n\nThe ion charge equals the number of electrons gained (-) or \nlost (+) by the atom to form the ion.

Any of a group of six elementary particles having electric charges of a magnitude one-third or two-thirds that of the electron, regarded as constituents of all hadrons.\n\n\nA soft creamy acid-cured cheese of central Europe made from whole milk.\n\n\nhypothetical truly fundamental particle in mesons and baryons; there are supposed to be six flavors of quarks (and their antiquarks), which come in pairs; each has an electric charge of +2/3 or -1/3 2: fresh unripened cheese of a smooth texture made from pasteurized milk, a starter, and rennet.

1.) 2Ni + O2 -->  2NiO  (since it's Nickel II and Oxygen has a charge of -2, but you always have to put oxygen in groups of 2)\n\n1.) 2H2O --> 2H2 +O2  (same with hydrogen)\n2.) 2Al2O3 (because Aluminum has a charge of +3) --> 4Al + 3O2\n3.) 2NaCl --> 2Na + Cl2 (basically the rest follow the same rules)\n4.) 2NH3 --> 3H2 + 2N\n5.) 2HgO --> 2Hg + O2

There are a lot of sites that have info.  Search for "formula writing polyatomic ions".\nIf you have a list of polyatomic ions like "SO4", "SO3", "PO4", etc. you will see that they have specific charges associated with them.  SO4 and SO3 both have a negative 2 charge.  Hydrogen has a +1 charge.  A compound must be neutral so you need 2 H to pair with one SO4.  +2-2=0.\nPO4 has a negative 3 charge, so you'd need 3 H+ to offset the 3 negatives.  H3PO4.\n\nAs far as naming them, search for "naming chemical compounds"  The examples you are asking about are actually acids, so you might need to look up "naming acids".

Elements differ primarily by number of protons.  An atom containing one proton, for example, is always called hydrogen.  Protons are contained in the nucleus along with neutrons.  Electrons "orbit" the nucleus  ("orbiting" isn't a correct way to describe the electron quantum mechanical sense, but it's more-or-less helpful to think of it this way).  Protons have a positive charge, electrons a negative charge and neutrons a neutral one.\n\nElements may also vary within themselves.  Some forms of elements have more neutrons than others.  These are called isotopes of each other and have different masses.  They're referenced by their mass numbers such as "Carbon-14" or "Carbon-12".  Here Carbon-14 has two "atomic mass units" (amu) more mass than carbon 12.  Each proton and each neutron contributes one amu to the mass so carbon 1-4 has two more neutrons than carbon-12.\n\nElements may also vary by electronic species.  When neutrally charged, the same number of electrons "orbit" the nucleus as there are protons in the nucleus.  Sometimes atoms either gain or lose some electrons to become negatively or positively chaged overall (as opposed to neutral where the positive proton charges cancel exactly the negative electron charges).  These are called "ionic species" or simply "ions".

You need to split the ionic compounds apart to find the individual ions you would find in these structures.\n\nMgO would produce Mg^2+ & O^2- ions.\n\nK2S would produce K^+ & S^2- ions.\n\nYou can find the charge values directly from the periodic table trends for the charges atoms assume when they are ionized.

Usually, the number of electrons determines the charge of the atom. The protons determines the identity of the atom (the element). Therefore, when two protons and two neutrons are emitted, you will haev a totally different element than before, not an anion (negatively charged ion or atom).

subatomic particles include the down, bottom, and strange quark with charges of -1/3 electron charge, the electron muon and tau lepton, and the sigma minus, the delta minus, and the omega minus.

Break this up into three questions to Yahoo Answers:\n\n1. What is the charge e of an electron?\n\n2. What is the mass m of an electron?\n\nand after those are answered,\n\n3. What is [...] divided by [...]?\n\nYou can "spend" more points that way. :-) :-)\n\np.s. And the answer is: The e/m ratio of an electron is a constant of nature the numerical value of which depends on the units used.
