The metalloid that has three valence electrons is Boron~
Actually Rb or Rubidium in zero state has the following
electron configuration:
<span>1s22s2</span><span>2p6</span><span>3s2</span><span>3p63d10</span><span>4s2</span><span>4p65s1</span>
However we can see that the ion has a 1 positive charge,
which means that it lacks 1 electron, therefore the answer from the choices is:
<span>d.
rb+: 1s22s22p63s23p64s23d104p6</span>
During summer, the Earth's orbit brings Australia closer to the sun (as compared to Europe during its summer), resulting in an additional 7% solar UV intensity. Coupled with our clearer atmospheric conditions, this means that Australians are exposed to up to 15% more UV than Europeans.

Answer:
Gasoline being used in the engine of a car producing exhaust
Explanation:
Hello,
As it is known, gasoline is the component which car engines use to gain energy in order to allow the movement, in such a way, gasoline experiences a combustion chemical reaction, which is a chemical change, induced by the spark that the oxygen provides to allow the combustion. Such chemical process turns both gasoline and oxygen into carbon, nitrogen and sulfur oxides, water, ashes, other side products and the aforesaid energy to move the car.
Best regards.
