CP.1.1: Understand and explain that atoms have a positive nucleus (consisting of relatively massive positive protons and neutral neutrons) surrounded by negative electrons of much smaller mass, some of which may be lost, gained, or shared when interacting with other atoms.
CP.1.2: Realize that and explain how a neutral atom's atomic number and mass number can be used to determine the number of protons, neutrons, and electrons that make up an atom.
CP.1.3: Understand, and give examples to show, that isotopes of the same element have the same numbers of protons and electrons but differ in the numbers of neutrons.
CP.1.5: Distinguish among chemical and physical changes in matter by identifying characteristics of these changes.
CP.1.6: Understand and explain how an atom can acquire an unbalanced electrical charge by gaining or losing electrons.
CP.1.8: Know and explain that the nucleus of a radioactive isotope is unstable and may spontaneously decay, emitting particles and/or electromagnetic radiation.
CP.1.9: Show how the predictability of the nuclei decay rate allows radioactivity to be used for estimating the age of materials that contain radioactive substances.
CP.1.10: Understand that the Periodic Table is a listing of elements arranged by increasing atomic number, and use it to predict whether a selected atom would gain, lose, or share electrons as it interacts with other selected atoms.
CP.1.12: Realize and explain that because mass is conserved in chemical reactions, balanced chemical equations must be used to show that atoms are conserved.
CP.1.13: Explain that the rate of reactions among atoms and molecules depends on how often they encounter one another, which is in turn affected by the concentrations, pressures, and temperatures of the reacting materials.
CP.1.15: Understand and explain that whenever the amount of energy in one place or form diminishes, the amount in other places or forms increases by the same amount.
CP.1.16: Explain that heat energy in a material consists of the disordered motions of its atoms or molecules.
CP.1.17: Know and explain that transformations of energy usually transform some energy into the form of heat, which dissipates by radiation or conduction into cooler surroundings.
CP.1.20: Realize and explain that the energy in a system is the sum of both potential energy and kinetic energy.
CP.1.21: Understand and explain that the change in motion of an object (acceleration) is proportional to the net force applied to the object and inversely proportional to the object's mass. (a=F/m)
CP.1.22: Recognize and explain that whenever one object exerts a force on another, an equal and opposite force is exerted back on it by the other object.
CP.1.23: Understand and explain that the motion of an object is described by its position, velocity, and acceleration.
CP.1.24: Recognize and explain that waves are described by their velocity, wavelength, frequency or period, and amplitude.
CP.1.25: Understand and explain that waves can superpose on one another, bend around corners, reflect off surfaces, be absorbed by materials they enter, and change direction when entering a new material.
CP.1.27: Recognize and describe that gravitational force is an attraction between masses and that the strength of the force is proportional to the masses and decreases rapidly as the square of the distance between the masses increases. (F = G[(m1m2)/r²])
