Red Rod Canyon
70
How many electrons are in the following ion:
16
70
What instrument is used to identify the elemental composition of a substance or a material by exciting the electrons and observing the photons (light)?
Spectroscope
70
What is the acceleration of the block?
0.2 m/s/s
70
What two numbers hold the universe together?
(hint: universal gravitational constant!)
70
Why are elements with very LOW ionization energy very reactive? (explosive)
Ionization is very LOW so it is easy for its valence electrons to ripped away and engage in a chemical reaction.
