DAT General Chemistry Questions and Answers | Latest Update | 2024/2025 | Graded A+ How is the periodic table arranged to reflect the properties of elements? The periodic table is arranged by increasing atomic number, with elements grouped into columns (groups) and rows (periods) that reflect similar chemical properties and trends in atomic structure. What is the role of a chemical equation in representing a chemical reaction? A chemical equation represents a chemical reaction by...

Week 2 Ionic Compounds IONIC COMPOUNDS In this lesson, you will be exploring ionic bonding. You have encountered many examples of molecules containing Ionic bonds including table salt and sodium fluoride which is found in toothpaste. We will see in this lesson how ionic compounds are formed and how the formation of these compounds leads to the properties we observe. Which of the following would be considered an Ionic Compound? A. CH4 B. LiCl C. N2O4 D. SO In general, an ionic bond for...

Chemistry Cumulative Review Latest Update Graded A+ Electronegativity The tendency of an atom to attract electrons in a chemical bond. It is not directly measurable. Metals have low electronegativity, meaning they do not hold onto electrons tightly and often lose them in reactions. Nonmetals have high electronegativity, meaning they hold onto electrons strongly and often gain electrons from other elements. Covalent Bond The sharing of electrons between two nonmetal atoms. ...
