- Fill in the blanks with the smallest integers possible. When gallium (Z=31) reacts with sulfur to form an ionic compound, each metal atom loses ______ electrons and each nonmetal gains_____electronss. There must be _____ gallium atoms for every _____sulfur atoms in the reaction.arrow_forwardWrite the chemical formula for the ionic compound that would form from the elements X and Z if a. X has two valence electrons and Z has seven valence electrons b. X has one valence electron and Z has six valence electrons c. X has three valence electrons and Z has five valence electrons d. X has six valence electrons and Z has two valence electronsarrow_forward7. Polyatomic ions combine in a similar way as the monatomic ions in that the charges must sum to zero. The only difference is that if more than one polyatomic ion is needed, a parenthesis is used and the subscripts are placed outside the parentheses. Write the formula of the compound formed by combining the following ions. Use the ion cut outs to help as needed. NO3 SO,2- PO43- NH4" Mg2+ Al3+arrow_forward
- Which is a difference between molecular compounds and ionic compounds? X That's not right. Molecular compounds typically form between a metal and a nonmetal, while ionic compounds typically form between nonmetals. Molecular compounds result from the transfer of electrons between atoms to form ions, while ionic compounds result from the sharing of electrons between neutral atoms. Molecular compounds are formed of discrete, neutral molecules, while ionic compounds are formed of large repeating arrays of opposite charges. Molecular compounds have high melting points and high boiling points, while ionic compounds are typicaly found as gases or low-melting solids and low-boiling liquids. Content attribution FEEDBACKarrow_forwardDecide whether each molecule or polyatomic ion is polar or nonpolar. If the molecule or polyatomic ion is polar, write the chemical symbol of the atom clos st to the negative side. For example, if the molecule were HCl and you decided the hydrogen atom was closest to the negative side of the mole ule, you'd enter "H" in the last column of the table. molecule or polyatomic ion polar or nonpolar? atom closest to negative side O polar CH, CI O nonpolar O polan 02 O nonpolar O polar OCS O nonpolar Explanation Check O 2021 McGraw-HiEducation.

SI Al 1arrow_forwardIons that form from one atom on the Periodic Table are call monatomic ions. However not all ionic bonds are formed with monatomic ions, polyatomic ions can form ionic bonds as well. The prefix poly- means many and atomic refers to atoms, so a polyatomic ion is an ion that contains more than one atom. This differentiates polyatomic ions from monatomic ions, which contain only one atom. Examples of monatomic ions include Na+, Fe3+, Cl-, and many, many others. We can think about polyatomic ions by comparing them to monatomic ions. A monatomic ion is an atom that has been ionized by gaining or losing electrons. The ion has a net charge because the total number of electrons is not balanced by the total number of protons in the nucleus. Thus, compared to the neutral atom, we have extra electrons—in the case of a negatively charged anion—or not enough electrons—in the case of a positively charged cation. For example, a neutral chlorine atom has an atomic number of 17, which means it has 17…arrow_forward
- Prefixes are not used in naming ionic compounds because the basic units of ionic compounds are molecules composed of constituent atoms ionic compounds are generally very stable the basic unit of an ionic compound is the formula unit O the charges on the ions dictate how many must be present to form a neutral unit O ionic compounds are usually composed of two or more covalently bonded metalloidarrow_forwardThe Nomenclature of different Polyatomic ions.
