GRADED A+
QUESTIONS & ANSWERS
Matter. ANSWER -Anything that has mass and occupies space
Kinetic Energy. ANSWER -Energy in action
Potential Energy. ANSWER -Stored energy
Chemical Energy. ANSWER -Stored in bonds of chemical substances
Element. ANSWER -Matter is composed of elements, cannot be broken into simpler
substances by ordinary chemical methods
Atom. ANSWER -Unique building blocks for each element
Proton. ANSWER -Positive charge, found in nucleus
Neutron. ANSWER -No charge, found in nucleus
Electron. ANSWER -Negative charge, Orbit nucleus in an electron cloud
Nucleus. ANSWER -Almost entire mass of the atom composed of Neutrons and Protons
Ion. ANSWER -Atom with net electric charge due to loss or gain of one or more electron
, Atomic Symbol. ANSWER -One or two letter chemical shorthand for each element
Isotope. ANSWER -Structural variations of atoms, differ in number of neutrons they
contain
Molecule. ANSWER -2 or more atoms bonded together; all compounds are molecules
Mixture. ANSWER -Two or more components physically intermixed
Solution. ANSWER -Homogeneous (same) Mixtures
Solvent. ANSWER -The dissolver
Solute. ANSWER -What's dissolved
Suspension. ANSWER -Heterogenous mixtures; large, visible solutes settle out
e.g. blood
Chemical Bond. ANSWER -Energy relationships between electrons of atoms; electrons in
valence shells
-has most potential energy
-chemically reactive electrons
Octet rule
Valence Shell. ANSWER -Outermost electron shell
Ionic Bond. ANSWER -Transfer of valence shell electrons from one atom to another forms
ions
