Answer:
Most metals have <u>luster</u> which means they <u>reflect</u> light
Explanation:
When light, which is made up of energetic photons, comes in contact with the surface of a metal, it is absorbed due to the corresponding energy gaps present between the metal orbital. The absorbed photons results in the raising of the energy levels of electrons within an atom of the metal which later drop back to a lower energy level and re-emit the photons which can now be observed as the metallic luster.
Answer:
<span>D. Remove electrons from its full outer energy level
</span>
Explanation:
The atom achieves its stable state when its outermost shell is completely full with 8 electrons (based on the octet rule)
Any atom whose outer shell is not completely full tends to lose gain or share electrons in order to complete this shell and become stable
Therefore, it is pointless for an atom with an outer shell having 8 electrons to lose electrons, because by this it convert from being stable to being unstable.

Answer:
3-1-5-2-4
Explanation:
scientists believe that the solar system was formed when some star had its explosion and due to its explosion there were waves generated in the space thus squeezing clouds and dust eventually gravity pulling everything together forming solar nebula. the clouds spin faster and faster thus making it into a thin disk and also the cloud becoming hotter and dense thus forming stars.

Answer:
= 55.7g
Explanation:
12g of carbon burnt to produce 5x10^2KJ
So, 5x10^2KJ(12g/393.5KJ)=15.2g
Then mas of CO2 is 44g
So, 15.2g(12g/44g)=57.7g
