** With Br ( column 7) has 7 electrons in outermost shell, it needs one more electron to satisfy the octet rule, so the charge on Br is - 1 ** Sr ( column 2 ) has only 2 electrons in outermost shell. Find the formula for ionic compounds. 2) The charge of ion is equal to its charge. View Chapter 7 HW from CHEM 150 at University of Phoenix. B) Be=, ber view the full answer. Predict the charge on the monatomic ions formed from the following atoms in binary ionic compounds: (a) I I-; -1 (b) Sr Sr2+; 1) The charges of single - atoms always be 0. Predict the charge on the monatomic ions formed from the following atoms in binary ionic compounds: (a) I (b) Sr (c) K (d) N (e) S (f) In. Praticar: Naming ionic compounds. ... Praticar: Predict the charge on monatomic ions. Praticar: Find the formula for ionic compounds. News; Impact; (a) | I has 7 valence electrons so it gains 1 electron to form I⁻ (charge 1-). To predict the charge on a monoatomic ion we need to consider the octet rule: atoms will gain, lose or share electrons to complete their valence shell with 8 electrons. Predict the charge on the monatomic ions formed from the following atoms in binary ionic compounds: (a) P (b) Mg (c) Al (d) O (e) Cl (f) Cs. Step #1 - the symbol of the cation is Fe. Predict the charge of the monatomic ions formed by $\mathrm{Al}$, $\mathrm{N… 07:24. Show transcribed image text. (c) K Predict the charge of common metallic and nonmetallic elements, and write their electron configurations As you have learned, ions are atoms or molecules bearing an electrical charge. Step #3 - the anion symbol and charge comes from the second name. (b) Sr Sr has 2 valence electrons so it loses 2 electrons to form Sr²⁺ (charge 2+). Oxide means O 2 ¯. Up Next. Using the periodic table, predict the charges of the ions of the following e… 01:26. Donate or volunteer today! To predict the charge on a monoatomic ion we need to consider the octet rule: atoms will gain, lose or share electrons to complete their valence shell with 8 electrons. Step #4 - since a formula must have zero total charge, you write the formula Cu 2 O. Predict the monatomic ion formed from different elements based on the position in the periodic table. Nonmetals tend to form anions with charges equal to their group number minus 8. Predict the charge of the ion formed by each element. Predict the charge of the ion formed by each element and write the electron … 01:05. (a) | I has 7 valence electrons so it gains 1 electron to form I⁻ (charge 1-). Main-group metals tend to form cations with charges equal to their group number (North American system). Find the formula for ionic compounds. Example #3 - Write the formula for: iron(III) sulfide.
