Elements in group 18 called Noble Gases are highly reactive because they have 1 valence electron.

Chemistry
1 answer:
lana [24]3 years ago
6 0

Answer:

False.

Explanation:

Noble gasses are extremely unreactive. They are called 'noble' because they do not mix with almost any other element, save flouride. They all, except helium, have a complete first and second valence level, meaning ten total electrons. Because of this they are very stable and do not want to receive any electrons or give any.

is there a relationship between the relative age of stars in the number/identity of element is found within them
lukranit [14]

Yes. Stars use fusion to create nuclear energy, which is what makes them "alive". The older they are, the "bigger" the element in them is. Hydrogen turns into Helium, and when hydrogen is used up, the helium starts fusing into bigger elements. it stops at iron however. Once stars start fusing silicon to iron, it is doomed because it takes more energy than it gives off.
