Answer:
The answer to your question is: The second option.
Explanation:
Atoms are stable when they gain or lose electrons to have 8 electrons.
They have one valence electron. Noble gases have 8 electrons, not one, If they would have 1 electron they would be extremely reactive.
They have eight valence electrons. This is the right answer, noble gases have 8 electrons that is why they are unreactive.
They have seven valence electrons. If noble gases would have 7 electrons, they would be very reactive.
They have two valence electrons. This option is incorrect, elements that have 2 electrons are reactive like Calcium, Magnesium, etc.
Answer:A fundamental difference is that physics is more focused to finding the universal laws of general processes, whereas chemistry focuses more on details and specific phenomena, such as what is the boiling point of this substance and why.
Explanation: hope it help
Answer:
Zinc metals was oxidized ,zinc ions were reduced
Explanation:
The zinc atoms lose electrons and becomes oxidized . And zinc ions gain electrons (becomes reduced)
<span>Answer: option A) it is stable.

<span>Justification:

</span><span>
</span><span>Radon (Rn) has atomic number 86. The electron distribution leads to the most stable configuration: the outermost shell (valence shell) is 6s² 6p⁶. That means that it has 8 valence electrons and, therefore, this shell is full. It will not accept more electrons ans will try to keep all of the ones it has.</span><span /><span />
<span>This is the typical configuration of a noble gas. They are all in the group 18 of the periodic table (the last column). So, as the other noble gases, He, Ne, Ar, Kr, and Xe, Rn is very stable.
