Answer: -
¹⁰B
Explanation: -
For ⁹Be,
The atomic number is 4.
The Mass number is 9.
The number of neutrons = mass number - atomic number
= 9 - 4 = 5
For ⁹B,
The atomic number is 5.
The Mass number is 9.
The number of neutrons = mass number - atomic number
= 9-5 = 4
For ¹⁰B,
The atomic number is 5.
The Mass number is 10.
The number of neutrons = mass number - atomic number
= 10-5 = 5
For ¹⁰Be,
TThe atomic number is 4.
The Mass number is 10.
The number of neutrons = mass number - atomic number
= 10-4 = 6
For ¹²C,
The atomic number is 6.
The Mass number is 12.
The number of neutrons = mass number - atomic number
= 12-6 = 6
Answer: A.nitrogen,oxygen,and argon
Explanation:

Hydrocarbons are chains of C and H. C and H are held together by covalent bonds.
hydrocarbons are of three main types
alkanes - only single bonds between C atoms
alkenes - double bonds between C atoms present
alkynes - triples bonds between C atoms present
saturated hydrocarbons definition is when there are only single bonds present
from the given compounds
propane - only single bonds
propene - double bond
propyne - triple bond
propanal - double bond between C and O
only compound with single bonds is propane
answer is propane
