Atoms/Elements
The 3 particles that make up an atom
What is neutron, proton, and electron
Give 2 examples of physical properties?
What is color, hardness, malleability, density, melting point, boiling point, conductivity, or solubility.
Lowest temperature possible. No motion, no heat.
What is absolute value.
True of False: A wave is a disturbance that carries energy from one place to another through matter and space.
What is true
Parts of the wave where the particles of the medium are close together. Parts of the wave where the particles of the medium are farther apart.
What is compressions and rarefactions?
How does an electron's energy change the further it is from the nucleus
What is have more energy at higher levels
Give 2 examples of changes of state and whether energy is gained or lost.
What is Melting (gain), freezing (lose), Condensation (lose), sublimation (gain), vaporization (gain)
Energy contained within a system and responsible for its temperature.
What is thermal energy
Energy is transferred through vibrating particles of _____________
What is Matter.
Name two ways that elements are alike in a column on the periodic table.
What is the same number of valence electrons and similar chemical properties.
What is protons=19 and Electrons=20
The same amount of matter exists before and after the change, even if it changes form.
what is the Law of Conservation of Mass
Heat transfer between particles in contact with each other.
What kind of wave carries energy through space where there is no matter?
Name the two types of ions and how are they formed.
What is cation (positively charged and lose electrons) and anions (negatively charged and gain electrons)
Metals _____ valence electrons. Nonmetals ____ valence electrons when forming chemical bonds.
What is Lose and gain
True or False: A physical change is a change in size, shape, or state of matter in which the identity of the substance remains the same.
What is True.
True or False: Convection is the transfer of heat from cold to hot in solids.
A __________wave transfers energy parallel to the direction of wave motion and a ______perpendicular to the direction of wave motion.
What is Longitudinal and transverse
What direction does reactivity increase as you move horizontally in a row of metals on the periodic table?
What is increases right to left across periods and increases down groups.
What are the 3 categories of elements on the periodic table and give one characteristic of each.
What is metals, nonmetals, metalloids. Give an example of each.
D=M/V
Energy transfers through space and speed of light.
What is Radiation?
What is trough, crest, amplitude, and wavelength.
What is the difference between an atom, ion, and isotope?
atoms have the same # of protons and neutrons, isotope has the same # of protons but different # of neutrons, and ion has different # of electrons and protons-its electrically charged.
