The positive charge on the NADP+, for instance. Giving a electron.

A potassium ion has one positive charge because it is missing one valence electron.   So K can form compounds with anything that is electronegative; in other words, any atom or molecule that likes to grab electrons. Anything at the right hand end of the periodic table, like O, S or the halogens for instance.   Or a more complicated compound would be with an organic acid like stearic acid; you replace one H with a K and you get a liquid soap.   If you used Na instead of K you'd get the usual solid soap.   When I was a kid in Britain, the soap in public bogs was liquid so you couldn't steal it.

I'll make it easy for you.All the metals forms positive ions by losing electrons and all non-metals form negative ions by gaining electrons.\nExample:- NaCl  Na+ & Cl-

If you mean the charge, that is zero for a neutral element - same number of electrons and protons. In practice for large atoms the distribution of electrons can get distorted a bit depending on circumstances, though,

A cation is a  positively charge ion as is the sodium. Two positively charged ions will repel each other. The anions will also repel each other because an anion is negatively charged like Cl. The negatively charged ions will repel each other. \n\nThink of it this way, if you have 2 magnets and you put the positive ends together then they repel, same with the negative. But if you put one positive and one negative side they stick together or bond.

NaOH + H2O---> Na+   +   OH-   +H20\n\nThere is no reaction, but sodium hydroxide will ionize in the water. Actually the water will ionize also.

Firstly,\nNaCl dissociates into Na+(aq) + Cl-(aq)\n1faraday of charge is required to produce 23 g Na from molten NaCl .\ntherefore production of 100000 g of Na will require charge = \n(1/23)*1000000 Faradays = 43478.26 Faradays = 43478.26 * 96500 C      [ as 1F = 96500 c]\n=4.1956 * 10^9 C\nBut, Q=IT \nso, T=Q/I = (4.1956 * 10^9)/300000 = 13.9855 * 10^3 secs = 3.88486 hrs.

Every atom has two unique numbers: Atomic Number (Z) and mass number (A). Atomic number Z represents the number of protons in the nucleus of an atom. Mass number A represents the number of neutrons and protons in the nucleus of an atom. When atoms are expressed on a periodic table, they are written with a number on the top and a number on the bottom. Z is written on the top and A is written on the bottom. Also when elements are represented with the name and a number on the upper lefthand side corner. This number represents the electrical charge of the atom. This is the number that tells us if the atom gained or gave away electrons.\n\nTo calculate the number of protons: Simply just look at the atomic number and it is the number of protons. For example Number of protons in a sodium atom is 11.(Z=11)\n\nTo calculate the number of electrons: Subtract electrical charge of the atom from the atomic number. For example Na+1 tells us that sodium atom gave an electron away. So 11-1=10 electrons present.\n\nBut the number of electrons is equal to the number of protons when the atom is not charged.\n\nTo calculate the number of neutrons: Subtract the atomic number from the mass number. For example, to find the number of neutrons in the nucleus of a sodium atom 23-11=12 neutrons.

The nuclear charge depends on the positively charged protons. Potassium has 19 protons and 20 neutrons. So, this makes the nucleus +19 and the mass of the atom 39 (19+20).

Cause Na, Sodium has 11 electrons, its electron configuration would be 1s2 2s2 2p6 3s1

Polyatomic ions are a group of atoms that stick together during a reaction. They have a charge because they are part of a compound, they attach to another atom  with an ionic bond. \nSO4  has a -2 charge because S is +6 and O is -2 for each O\nNH4 is +1 because N is -3 and each H is +1

the formula is NaO2\nthis is because the superoxide has the formula (O2)- and the sodium ion has the formula Na+

No concrete way to work it out. Groups one and two take positive charges equal to their group number (Mg2+, Li1+ etc). Groups 3, 4, 5, 6 and 7 ionise to a negative charge of 8 minus their group number (Cl1-, O2- etc), though 3, 4, and 5 tend to resist ionisation and are much more commonly found bonded covalently. The Transition elements ion charges are virtually impossible to predict without an extensive knowledge of d orbitals etc..

18F\nFluorin has 9 protons(9+)and 9 electrons(9-).Therefore,there'll be no charge since positive charges from 9 protons were neutralize by negative charges of 9 electrons.+9-9=0..It is known as atom because it doesn't carry any charge.If it is ion,the amount of electron will more than proton,or the other way round.\n\nHope this will help!!=)All the best!!

K2SO4\nCa(NO3)2\n\npotassium has a +1 charge and sulfate has a -2 so therefore you need 2 potassiums so that you can have a net zero charge.\ncalcium has a +2 charge and nitrate has a -1 charge so you need two nitrates to balance the charges

A cation (not kation) is an ion with a positive charge and an anion is an ion with a negative charge. What exactly do you mean analysis? Hope it is somewhat helpful.
