Charge and Columns Figure 5: The charge of an ion can be predicted by its position on periodic table Main group elements have predictable charges they assume when they become ions. Note the usefulness of the periodic table in predicting likely ion formation and charge (Figure \(\PageIndex{2}\)). For example, the magnesium 2+ ion is written as Mg2+. Group 7 ions have -1 charges. (b) A sodium cation (Na+) has lost an electron, so it has one more proton (11) than electrons (10), giving it an overall positive charge, signified by a superscripted plus sign. (a) magnesium (b) zinc (c) nickel (d) gallium. Chlorine has 17 electrons (a charge of -17) and 17 protons (a charge of +17), so the overall charge is zero.

Fuse School, Open Educational Resource free of charge, under a Creative Commons License: Attribution-NonCommercial CC BY-NC (View License Deed. A binary compound is one made of two different elements. Monatomic ions can be positive or negative and just like magnets, oppositely charged ions will attract, and ions with the same charge will repel each other. Atoms of group 17 gain one electron and form anions with a 1− charge; atoms of group 16 gain two electrons and form ions with a 2− charge, and so on. Write the symbol for each ion and name them. (a) selenium (b) fluorine (c) iron (d) nitrogen. Figure \(\PageIndex{1}\): (a) A sodium atom (Na) has equal numbers of protons and electrons (11) and is uncharged. Predict which forms an anion, which forms a cation, and the charges of each ion. If that happens, then atoms in group A lose 1 electron to form monatomic cation. In fact, transition metals and some other metals often exhibit variable charges that are not predictable by their location in the table. Thus, a nitrogen atom will form an anion with three more electrons than protons and a charge of 3−. Have questions or comments? To illustrate, an atom of an alkali metal (group 1) loses one electron and forms a cation with a 1+ charge; an alkaline earth metal (group 2) loses two electrons and forms a cation with a 2+ charge, and so on.

Main-group metals tend to form cations with charges equal to their group number (North American system). Paul Flowers (University of North Carolina - Pembroke), Klaus Theopold (University of Delaware) and Richard Langley (Stephen F. Austin State University) with contributing authors. Chapter 7 6. You can predict the charge of an ion by looking at its group number on the periodic table. If an ion contains more than one atom, even if these are of the same element, it is called a polyatomic ion. Common polyatomic ions. There can be one of each element such as in CuCl or FeO.There can also be several of each element such as Fe 2 O 3 or SnBr 4.. Knowing this lets us use the periodic table to identify the element as Al (aluminum). The elements in Groups 1A and 2A and 3A form cations. When atoms of nonmetal elements form ions, they generally gain enough electrons to give them the same number of electrons as an atom of the next noble gas in the periodic table. Learn vocabulary, terms, and more with flashcards, games, and other study tools. Groups IA, IIA and IIIA all lose electrons and become positively charged. To begin with, the electrons and protons are balanced. Determining Charges on Monatomic Ions 1. Predict the charges of the monatomic (single-atom) ions formed by these main-group elements. Write the symbol for each ion and name them. One can use the periodic table to predict whether an atom will form an anion or a cation, and you can often predict the charge of the resulting ion. Nitrogen’s position in the periodic table (group 15) reveals that it is a nonmetal. Monatomic ions are chemically represented by the element's symbol with the size and type of charge written as a superscript to the right of the symbol.
