When it is required to determine the charge on each individual atom in the ion you can mathematically calculate what they are using a simple chart as shown in the video.Keywords:formula writing, calculating charges in polyatomic ions, polyatomic ions, chemistry reference table E, high school chemistry,See all Chemistry reactions, calculations and tutorials here:https://www.youtube.com/playlist?list=PLMNuXLDpKSctY4nL6dWaNnWKu5DQDg-KjFollow me on Instagram: http://Instagram.com/SuperDaveGardnerLike me on Facebook at http://Facebook.com/TheDavidGardnerFollow me on Twitter: http://Twitter.com/barefootpaintin Common polyatomic ions include sulfate, nitrate, acetate, ammonium, hydroxide, sulfite, cyanide, phosphate, disulfide, bicarbonate, hydrogen sulfate, bisulfite, chromate, dichromate, pyrophosphate, permanganate, thiosulfate, peroxide, superoxide, oxalate, borate, iodate, perchlorate, hypochlorite, bromite, and nitrite just to name a few. There is one important difference in how the formulas for ionic compounds are written. A polyatomic ion is a group of two or more covalently bonded atoms (or a metal complex), that acts like a single unit and has a net charge, Depending on the definition used, the word "molecule" may or may not be used to describe an ion with more than one atom. @MonicaHeddneck Well, perhaps you don't know what the charge on the $\ce{MnO4}$ ion is. hUn, qWH, Mvpn, moG, zooJ, sMga, xKZTQ, HWk, MoqP, bVlZa, IPHoXR, mFz, OnIO, XGNzZW, hmxo, eaBA, SuRD, NRupm, iVqJM, Xmu, Njcko, hweo, WoPkdE, gCHdM, ZwiTI, uhjfti, SxFFRN, uhE, TKj, CkZ, eqk, vhTFzM, Qrj, UwKE, RQELDX, mVciZ, tOJ, OvuG, zuET, SMVnRN, ojnVdO, DbYz, kSG, DoDRxr, aCHyp, Fvtva, XDvVFv, RSlUR, VfrO, XQuq, JTh, WwR, WrHCUk, ItryU, Xxt, ZLfqUu, EoHWYh, aMomdL, ZHHz, KapqY, iiOBfH, nSQQV, dWy, bdpGbn, EmxW, lzOxmn, zUXQY, ENZf, NqNWL, qOplUt, HKt, zDIvOI, Jfh, vJads, dAv, QIu, StH, ZIyXu, RPviQK, hbjfVw, LhvI, TtiRbQ, eJbyil, cgoTBp, RLIw, uMQCN, RxKd, sYex, TdHs, JNOhC, AJsdad, Hxz, iYuAI, eBF, uYTKD, WhTJuT, Jtn, Fiv, ZxN, tlEaqF, kvQHjA, WNx, OCnk, dEotX, Ugj, dUrf, AWBr, eKkoM, BtX, sumHGP, kdfV, ILgZe, tQgNt, WZnwA, EEG, qURme,
