Predict the monatomic ion formed from different elements based on the position in the periodic table. (c) K Khan Academy is a 501(c)(3) nonprofit organization. => The charge of Br = 0 and the charge of Sr = 0. 2. Determining Charges on Monatomic Ions 1. Expert Answer 100% (1 rating) A) in electronic configuration of sulfur : sulfur needs two electrons to complete its octet. 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. News; Impact; Metals form cations; nonmetals form anions. Step #1 - the symbol of the cation is Fe. Find the formula for ionic compounds. (b) Sr Sr has 2 valence electrons so it loses 2 electrons to form Sr²⁺ (charge 2+). Show transcribed image text. Main-group metals tend to form cations with charges equal to their group number (North American system). Problem: Predict the charges of the monatomic (single-atom) ions formed by these main-group elements. 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. (a) | I has 7 valence electrons so it gains 1 electron to form I⁻ (charge 1-). Up Next. ... Praticar: Predict the charge on monatomic ions. Step #3 - the anion symbol and charge comes from the second name. Example #3 - Write the formula for: iron(III) sulfide. Predict the charge on monatomic ions. 1) The charges of single - atoms always be 0. Predict the charge of the ion formed by each element. Praticar: Naming ionic compounds. 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. Predict the charge of the monatomic ions formed by $\mathrm{Al}$, $\mathrm{N… 07:24. Examples: Na+ (Group 1A, 1+) Mg2+ (Group 2A, 2+) Al3+ (Group 3A, 3+) 3. Predict the charge on the monatomic ions formed from the following atoms in binary ionic compounds: (a) I I-; -1 (b) Sr Sr2+; Nonmetals tend to form anions with charges equal to their group number minus 8. 2) The charge of ion is equal to its charge. Step #4 - since a formula must have zero total charge, you write the formula Cu 2 O. Predict the charge of the ion formed by each element and write the electron … 01:05. Using the periodic table, predict the charges of the ions of the following e… 01:26. Chapter 7 HW 6. View Chapter 7 HW from CHEM 150 at University of Phoenix. Step #2 - the charge on the cation is a positive three. (a) N(b) Rb FREE Expert Solution For each group in the periodic table, we have: ** 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. Este é o item selecionado atualmente. 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. B) Be=, ber view the full answer. 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. (b) Sr. Sr has 2 valence electrons so it loses 2 electrons to form Sr²⁺ (charge 2+). Our mission is to provide a free, world-class education to anyone, anywhere. Find the formula for ionic compounds.
