They are very stable. they have a "full table" so to speak. they have no valance electrons. they do not give electrons and they do not take them either. there are very few if an elements that can be paired with noble gasses
Answer:
Average atomic mass = 14.0067 amu.
Explanation:
Given data:
Abundance of 1st isotope = 99.63%
Atomic mass of 1st isotope = 14.003 amu
Abundance of 2nd isotope = 0.37%
Atomic mass of 2nd isotope = 15.000 amu
Solution:
Average atomic mass = (abundance of 1st isotope × its atomic mass) +(abundance of 2nd isotope × its atomic mass) / 100
Average atomic mass = (99.63×14.003)+(0.37×15.000) /100
Average atomic mass = 1395.119 + 5.55 / 100
Average atomic mass = 1400.67 / 100
Average atomic mass = 14.0067 amu.
