Chapter 2 PPT Flashcards
when energy is actually doing work
kinetic
results from the movement of charged particles - ions
electrical energy
building blocks of elements
atoms
have the same number of protons and electrons so same atomic number
isotopes
vary in number of neutrons so different atomic masses
isotopes
process of spontaneous atomic decay
radioactivity
what are the particles release by radioactivity
alpha, beta and gamma rays
two or more atoms combined chemically
molecule
two or more DIFFERENT atoms combined chemically
compound
negatively charged ions
anions
positively charged ions
cations
form when electrons are completely transferred from one atom to another
ionic bonds
can either donate or accept electrons
ions
atoms become stable through shared electrons
covalent bonds
share one electron pair
single covalent bonds
share two electron pairs
double covalent bonds
can be found outside?
valent
hydrogen is attracted to negative portion of polar molecule
hydrogen bonds
provide attraction between molecules
hydrogen molecule
carries a positive and negative region
polar
synthesis reaction
A+B —-> AB
atoms or molecules are combined
synthesis reaction
anabolic reaction
synthesis reaction
reaction that absorbs or consume energy
anabolic
building blocks of protein
amino acids
proteins participate in?
muscular hyperthrophy or paglaki ng muscles
AB—> A+B
decomposition reaction
catabolic
decomposition
process that produces energy
catabolic
involves both synthesis and decomposition reactions
exchange reaction
have carbon
organic compounds
do not have / lack carbon
inorganic compounds
absorbs pressure to lessen the damage
cerebro spinal fluid
