Coach Wallace Vocab Flashcards
Subatomic particle inside the nucleus of an atom that has no charge (neutral)
Neutron
Subatomic particle that orbits the nucleus of an atom that has a negative charge
Electron
The dense, positively charged region in the enter of an atom made up of protons and neutrons
Nucleus
Subatomic particle inside the nucleus of an atom with a (+) positive charge
Proton
The smallest particle into which an element can be divided and still be the same substance
Atom
Elements that are full an are poor conductors of thermal energy and electric current
Non-Metals
Elements that are shiny and are good conductors of thermal energy and electric current
Metals
Contains only one type o particle Example: Elements and Compounds
Pure Substance
A mixture that appears to be a single substance containing a solute and a solvent
Solution
The substance in which the solute is dissolved to form a solution
Solvent
Pure substance that cannot be separated by physical or chemical means
Element
A pure substance composed of two or more elements that are chemically combined
Compound
Combination of two or more substances that are not chemically combined
Mixture
Rain, snow, sleet, or hail that falls from clouds to the Earth’s surface
Precipitation
Alters the substance but doesn’t change its identity
Physical Change
The continuous movement of water between the Earth’s surface and its atmosphere
Water Cycle
Elements that have properties of both metals and non metals
Metalliods
The substance that is dissolved to form a solution
Solute
Can be observed or measured without changing the identity of matter
Physical Property
Describes how a substance can change into a new substance with different properties
Chemical Property
Water that flows across the land and enters rivers, streams, lakes, and the ocean
Run Off
Water vapor cools and changes into liquid water droplets and forms clouds
Condensation
Liquid water changes into water changes into water vapor and enters the atmosphere
Evaporation
Causes the substance to change into a new substance with different properties
Chemical Change
