Ответ:
group 18 has 8 valence electrons, that's why they are stable.
Ответ:
8!
Explanation:
You're looking at the very last column, right? Noble gases are known for their stability because their valence shells are full! Lucky for you, all you have to do to know the number of valence electrons is look at the column number and take ignore the 1! 16 becomes 6, 18 becomes 8.
Ответ:
I learned that they helped me learn a lot. Scientific observations are like the moon and weird creatures. Mine are somthing simple like figuring out math. or finding a magnificint creature that everybody else knows about.hope this helps.
