Knowledge and Skills Statement

Science concepts. The student knows how atoms form ionic, covalent, and metallic bonds.

The further explanation is designed to be a resource for educators that helps them better understand the topic their students are learning. Further explanations may be written at a more complex level than would be expected for students at the grade level.

For example, caffeine is the common English name for 3,7-dihydro-1,3,7-trimethyl-1H-purine-2,6-dione. The IUPAC name encodes the structure and composition of the molecule and allows a chemist to unambiguously reference the molecule.

Glossary terms and definitions are consistent across kindergarten through high school in the TEKS Guide. The definitions are intended to give educators a common understanding of the terms regardless of what grade level they teach. Glossary definitions are not intended for use with students.

the smallest particle of matter that has distinct physical and chemical properties; consists of a nucleus which contains protons and neutrons and an electron cloud which contains electrons

type of bond that results from the sharing of an electron pair between two atoms

compound that shares one or more pair of valence electrons

type of bond formed from the electrostatic attraction between oppositely charged ions in a chemical compound

compound made up of ions, charged particles that have gained or lost electrons

a type of chemical bonding that is responsible for the characteristic properties of metals; arises from the electrostatic attractive forces between free electrons and positively charged metal ions

Buendía-Atencio, Cristian, Gilles Paul Pieffet, and Vaneza Paola Lorett Velásquez. "WERNER: A Card Game for Reinforcement Learning of Inorganic Chemistry Nomenclature." Journal of Chemical Education 99, no.5 (2022): 2198. https://doi.org/10.1021/acs.jchemed.2c00166

Summary:  Identifying and naming inorganic compounds is sometimes a challenge for many first-year chemistry and engineering students; however, these difficulties can be overcome after extensive practice using homework sets based on naming inorganic compounds or applying inorganic nomenclature rules. In the classroom, a card game was used immediately after explaining the basic nomenclature rules. Overall, the students found the game engaging and enjoyable, and they responded favorably to its use as an educational didactic tool.
