Distance/ Time which means Distance is on horizontal and time is on vertical
Elements with 7 valence electrons are extremely reactive, while elements with 8 valence electrons practically don't react at all.
This is caused by the fact that all molecules want to have 8 valence electrons; that's just the scientific fact. So, if an element already has 8 valence electrons, it doesn't need to react with anything. If the element only has 7 valence electrons, however, it really wants to react with something with 1 valence electron to get to that special number 8.
Metal conducts heat quicker than wood or air so when you touch it heat is taking away from you body faster than when you touch the wood desk. When heat is taken from our bodies our brain interprets this as cold.
Answer:
The evidence that supports the wave particle nature of light as a wave is:
"Light reflects when it hits a surface."
Explanation:
Light exhibit wave-particle duality. This means, in some cases the properties of light are just like a wave and in other cases it behaves as particles.
The properties like reflection or refraction from a surface are attributed as properties of waves. The phenomena of interference and diffraction also fall in this category.
Therefore, from the given options, the only option that supports the evidence of light as a wave is "Light reflects when it hits a surface", as reflection is entirely the property of a wave.
