Question

a is made up of two elements where one is a metal and the other a nonmetal. polyatomic ion oxyanion molecular compound binary ionic compound question 10 1 pts because substances must be electrically neutral, the total positive charge on the cations must equal the total number of negative charges on the anions. true false

Explanation:

1. For the first question, a binary ionic compound consists of two elements, one metal and one non - metal. A polyatomic ion is a group of atoms with a charge. An oxyanion is a polyatomic ion containing oxygen. A molecular compound is usually formed by non - metals.
2. For the second question, substances are electrically neutral, so the total positive charge of cations must equal the total negative charge of anions. This is a fundamental principle in chemistry related to charge balance in compounds.

Answer:

1. D. binary ionic compound
2. True
