overall endothermic reaction – energy required is greater than energy released
John Newland – First to discover the periodic table
In order by increasing atomic mass
Noticed a pattern every 8 elements- called it the law of octaves
What happened to the carbon dioxide? – After photosynthetic organisms had developed, they removed carbon dioxide from the atmosphere, replacing it with oxygen. Also, some was dissolved in the oceans.

Nanoscience – Based on particle on billionth of a metre in size.
energy – capacity to do work or produce heat
Mean value – A type of average, found by adding up a set of measurements then dividing by the number of measurements.
Molarity is a measure of
line-emission spectrum – a diagram or graph that indicates the degree to which a substance emits radiant energy with respect to wavelength
46)What are some household substances that are bases? – soap, lye, ammonia, clorox
what is the formula name for MnO₄ – permanganate
What were the results of Ernst Rutherford's gold foil experiment? – The results were that most of the radiation passed through the foil with little deflection and a small portion was deflected at wide angles. This meant that the atoms contained a small center (nucleus) which accounted for most of the atom. Rutherford also determined that most of the volume of an atom was empty space.
Gram (g) – a metric unit of weight equal to one thousandth of a kilogram
mass number – the total number of protons and neutrons in the nucleus of an atom
