Answer:

are gases at room temperature

usually do not react with other elements

are in a group called the noble gases

are nonmetals

Explanation:

The elements in group 18 or group O are the inert elements. They have completely outermost shell and are not reactive. Every atom reacts with another in order to be like the noble gases.

  • All of the elements here are gaseous.
  • They do not readily react with other elements.
  • They are called noble gases, inert gases, or group O elements.

It should be noted that group 17 elements are very reactive compared to the group O elements.

The atomic weight of boron is reported as 10.81, yet no atom of boron has the mass of 10.81 amu. explain
aivan3 [116]
<span>Boron has a lot of different isotopes, most of which having a very short half life (ranging from 770 milliseconds for Boron-8 down to 150 yoctoseconds for boron-7). But the two isotopes Boron-10 and Boron-11 are stable with about 80.1% of the naturally occurring boron being boron-11 and the remaining 19.9% being boron-10. The weighted average weight of those 2 isotopes has the value of 10.81. The reason they use the average mass of an element for it's atomic weight is because elements in nature are rarely single isotopes. The weighted average allows us to easily compare relative number of atoms of one element against relative numbers of atoms of another element assuming that the experimenters are getting isotope ratios close to their natural ratios.</span>
