Check my answer 100 points. tell me if they are wrong! 1. you have three elements, a, b, and c, with the following electronegativity values: a = 0.9 b = 3.0 c = 3.5 you react the elements to form the substances ab, ac, and bc. answer the following questions: • what type of substance is ab? what types of bonds are present? explain your answer. • what type of substance is ac? what types of bonds are present? explain your answer. • what type of substance is bc? what types of bonds are present? explain your answer. • if any of the substances are ionic compounds, which element is the cation and which is the anion? explain your answer. ab is an ionic compound. the electronegativity is different between a and b is greater. ac is an ionic compound. the electronegativity is different between a and c is greater. bc is a covalent compound because the electronegativity difference between a and b is small. ab and ac is an ionic compound. a is the cation and b and c are the anion because the element with lower electronegativity is a cation and the element with the higher electronegativity is an anion making a the cation and b and c an anion. your score of 5
