Hierarchy of organization correct answers -atoms, molecules, cell, tissue, organs, organ system,
organism
-organism, population, community, ecosystem, biosphere
characteristics of living things correct answers organized, need nutrients and energy, respond to
stimuli, reproduce and develop, adapt
Scientific process correct answers observation, hypothesis, experiment/further observation, data,
conclusion
homeostasis correct answers internal balance, process by which organisms maintain a relatively
stable internal environment
element correct answers 92 natural occurring, Carbon hydrogen, nitrogen, oxygen, phosphorus,
sulfur
CHNOPS correct answers Carbon, Hydrogen, Nitrogen, Oxygen, Phosphorus, Sulfur
atom correct answers smallest particle of elements
atomic number correct answers number of neutrons in the atom
atomic mass correct answers neutrons + protons
periodic table correct answers vertical- groups, chemically similar
horizontal- periods, larger and larger
, isotopes correct answers atoms of the same element that have different numbers of neutrons
electron shells correct answers different energy levels referred to as electron shells
oclet rule correct answers inner shell has 2 orbitals, others have 8, or multiples of 8
if 3 or less correct answers tends to donate
if 5 or more correct answers tends to recieve
molecule correct answers two or more atoms bonded together
compound correct answers group of atoms where at least one is different
chemical bonding correct answers bonds between atoms caused by electrons in outer most shells,
bond formation is called reaction
ionic bond correct answers chemical attraction between ions of opposite charge
ex: sodium and chloride.
covalent bonds correct answers form when electrons are shared between atoms
hydrogen bonds correct answers weakest, H becomes slightly +, O slightly -
