Naming monatomic ions and ionic compounds. Chlorine has 17 electrons (a charge of -17) and 17 protons (a charge of +17), so the overall charge is zero. That is, group 1 elements form 1+ ions; group 2 elements form 2+ ions, and so on. (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. Electrons, however, can be added to atoms by transfer form other atoms, lost by transfer to other atoms, or shared with other atoms.

Naming ionic compound with polyvalent ion. Group 6 ions have -2 charges. 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. Predict the charge on the monatomic ions formed from the following atoms in binary For each group in the periodic table, we have: 81% (118 ratings) Problem Details. Note the usefulness of the periodic table in predicting likely ion formation and charge (Figure \(\PageIndex{2}\)). This trend can be used as a guide in many cases, but its predictive value decreases when moving toward the center of the periodic table. A monatomic ion is an ion consisting of exactly one atom. Moving from the far left to the right on the periodic table, main-group elements tend to form cations with a charge equal to the group number. If Group 2A give up 2 electrons, they would have a charge of +2. 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. (A discussion of the theory supporting the favored status of noble gas electron numbers reflected in these predictive rules for ion formation is provided in a later chapter of this text.). You can predict the charges on most metal monatomic ions by looking at the group number. The elements in Groups 1A and 2A and 3A form cations. What is the charge on the common monatomic ions of the following elements? Give the symbol and name for the ion with 34 protons and 36 electrons. 2.
