Chemistry Chapter 4 Flashcards

Study Notes

Element Classification Terms

Symbol: Represents an element using one or two letters, providing a standardized shorthand for chemical identification.
Periodic Table: Organized display of chemical elements, sorted by increasing atomic number, showcasing elemental properties and relationships.
Isotope: Variation of an element's atoms that share the same number of protons and electrons but differ in neutrons, leading to different mass numbers.
Atomic Mass: Calculated average mass of all isotopes of an element, reflecting the relative abundance of each isotope in nature.

Groupings in the Periodic Table

Family: A column in the periodic table containing elements that exhibit similar chemical properties and behaviors, facilitating predictable patterns in reactivity.
Metal: Typically solid at room temperature (except mercury), these elements are characterized by luster, malleability, ductility, and excellent electrical and thermal conductivity.
Alloy: Combination of two or more metals, resulting in materials that often have enhanced properties compared to the individual elements.
Nonmetal: Elements that lack the physical and chemical characteristics typical of metals; they may be gases, liquids, or solids at room temperature, and often are poor conductors of heat and electricity.
Noble Gas: Group of elements that are inert due to their full outer electron shells; they do not commonly react with other substances, providing stability.
Inert: Referring to elements or compounds that do not engage in chemical reactions under standard conditions, emphasizing their lack of reactivity.
