THe name of this alkane is <span>1-ethyl,3-methylcyclohexane</span>
2 amu atomic mass units, a scale based on carbon 12
No. The most nonactive family on the periodic table is the Noble Gases, because they have a full valence electron shell and cannot bond with other atoms. The noble gases are considered as "chemically stable."
The best choice that explains why atoms of carbon-14 (c-14) are unstable is there are 2 more protons than neutrons in the nucleus
<h3>
What is a stable atom?</h3>
An atom is said to be stable if the number of neutrons in the nucleus is greater than number of protons in the nucleus, because the the neutrons increases the nuclear force which keeps the atom stable.
Thus, the best choice that explains why atoms of carbon-14 (c-14) are unstable is there are 2 more protons than neutrons in the nucleus.
