in a cation are there more protons than electrons or more electrons then protons?

There are more protons than electrons. Protons are plus. Electrons are minus. In hydrogen ion, there is one proton and zero electrons!

Do you mean 2000 times the mass?  Sounds like a proton.  An electron has a mass of 9.109 x 10^-31 kg while a proton has a mass of 1.673 x 10^-27 kg, about 1837 times as great.  An electron has a negative charge and a proton has a positive charge.  Despite the difference in mass, the electrical charges are equal in magnitude.

K+; its a CATION because it carries a positive charge\nions that have a negative charge are called anions\n\nCa(+2): cation\nGa(+3):  cation\nN(-3): anion\nBr(-):  anion

The atomic number equals the number of protons.  Electrons should equal the number of protons, but may not if it's an ion.  Neutrons vary as to the specific isotope of the atom.\n\nExample:\nHydrogen, atomic number = 1.  Therefore, 1 proton, 1 electron.\nIt has three isotopes:\nH-1 (1 proton, 1 electron, no neutrons)\nH-2 (1 proton, 1 electron, 1 neutron)\nH-3 (1 proton, 1 electron, 2 neutrons).\n\nYou might check the section you are asking this in, though.  This is the Religion section.

An ion is an atom that has acquired a net electrical charge.  An atom is uncharged because its number of electrons and protons are equal, and the magnitude of the negative charge of an electron is equal to the magnitude of the positive charge of a proton.  An ion has the same number of protons as the atom from which it formed, but a different number of electrons.  A negative ion (or anion) has one or more extra electrons, while a positive ion (or cation) has one or more electrons missing.  Atoms give up or accept electrons to become ions because it leaves them with a full and therefore stable outer electron shell.

the chemical formula is CaO. So total no. of electrons are \nequal to sum of electrons in Ca and O. \nElectrons in Ca = 20\nElectrons in O  = 8\nSo total electrons = 28\nsince no. of electrons is equal to that of protons,\nHence answer is = 28

Electrons can only have certain energy levels.  These levels are determined by a set of mathematical laws.  Potassium has 19 electrons. The first 18 complete the lowest 3 energy levels (similar to the element Argon).\n\nThe only available position for the 19th electron is in the next higher (4th) energy level.  These is no "room" for it to "squeeze in" the lower level.

Calcium is in the second column of the periodic table, meaning that it has two electrons in its outermost s-shell.\n\nThat means that as an element, it really "wants" to get rid of those two electrons.  So it's going to "try" to be a 2+ ion.\n\nLikewise, Oxygen is in column 6, meaning it has 6 electrons in it's outermost p shell.  Meaning it "wants" to gain 2 electrons to fill up its p-shell.  So it's going to try to be in molecules where it can share two electrons with other atoms.

The ion has one ore more surplus electrons to fill the outer shell to 8 of them.\nElectrons repell each other, so they take a little bit more space.\nSo the negative ion is a bit bigger than the atom.

The periodic table elements atomic number will tell the number of protons found in the atom.  The number electrons will be same as the number of protons.\n\nHowever, if the atom is an "ion", it could more or fewer electrons than there are protons.  These are refered to as anions and cations (cat-eye-ons) respectively.\n\nThe net electric charge of N+ or N- written as a superscript to the atom will reflect the number of additional or fewer electrons for the ion.

A neutral atom is redundant. The atom is neutral by nature. When the atom gets a positive charge then becomes a cation and when it gets a negative charge, becomes an anion.\nin the atom, the positive charges (protons) and the negative charges (electrons) are balanced.

sodium ions are one short in electrons than the sodium atoms while number of protons remain the same .Hence the nucleus exerts extra attractive force on the electrons resulting in the shrinking of the size of the ion.

Na is larger than Na+.\nF is larger than F+.\nCations are always smaller than the parent atom as the effective nuclear charge acting on an electron increases as the total number of electrons decreases.\nIn the case of Na&Na+,Na+ has one whole shell lesser than Na.

as i have explained with the formation of ionic compounds. this is an ionic compound like table salt (NaCl)\nLithium gives up the one outermost electron to Chlorine which has a stable octet.\nLithium then has just two. Remember, this is the first orbital (s orbital) with a maximum of two electrons.

um...  subtract???  hahaha\n\nThe higher the differences in electronegativity, the more ionic the compound.  The higher electronegative atom/ion will want to "hog" all the electrons.  They are greedy like that.  They don't want to share (which would be a covalent bond).

Chlorine ion has one more electron than cholorine atom.  It take on one more electron to have the same number of electrons as the nearest noble gas: argon.\n\nFluorine atoms gain one more electron to become an ion.  One more negative charge.  It takes on one more electron to have the same number as the nearest noble gas: neon.  Fourth answer only.
