If it is saturated compound then we can calculate the double bond equivalent which will be equal to the number of rings in the compound
the double bond equivalent can be calculated using following formula

Where
H = number of Hydrogen atoms
C = number of carbon atoms
X= number of halogen atoms
N = number of nitrogen atoms
DBE = (10 + 1 - 16 / 2 ) = 3
Hence there are three rings in the compound
Answer:
by changing the number of protons in the atom
Explanation:
Elements are defined by their number of protons. For example, an element with 1 proton is hydrogen, and an element with 2 protons is helium. Changing the number of neutrons or electrons in a preexisting element will not make a new element. Is is possible to create new elements, but it requires large amounts of heat and/or pressure.
This is because it has a full outer valence shell! so there are 8 electrons and that means it doesn't have the urge the gain anymore
Explanation:
this is the answer of your question .
