I think the number of protons in the nucleus the number of valence electrons atomic mass...
Answer:
Electrons can jump from energy level to energy level (for example energy level 1 to 2) but they can NEVER be found in between energy levels.
Density = Mass/Volume => Mass = Density*Volume => Mass = 3g/ml*10ml =30g
Difference Between Chemical and Physical Weathering.
Weathering processes crack, wear away, and weaken rocks.
While physical weathering breaks down a rock's physical structure, chemical weathering alters a rock's chemical composition.
Answer:
The Ideal Gases are described under the standard conditions to eliminate as many variables as possible.
Explanation:
P*V = n*R*(temp final-temp initial) There are standard conditions for the relationships between pressure (P), Volume (V), number of moles (n), and the temperature in Kelvin (K) or Celsius (C).
