Moving a spring back and forth creates a longitudinal wave
Answer:
kinetic and potential energy). The opposite is true when you remove thermal energy: Particles move slower (less kinetic energy). Particles get closer together (less potential energy)
Magnitude of change is 15km/h
change in direction is to the right?
Magnesium is in group 2 while sulfur is in group 6.
the group number determines the number of valence electrons.
Metals gives lose electrons (mg)
Non Metals gain electrons (s)
answer: Magnesium gives 2 electrons to sulfur.
Mg is now 2.8
Sulfur is 2.8.8
cuz ionic bonding
