- a)22
- b)44
- c)66
- d)88
Correct answer is option 'A'. Can you explain this answer?
Verified Answer
The total number of electrons in one molecule is carbon dioxide isa)22...
Logic:
Number of electrons in a molecule is equal to the sum of electrons in individual atoms in it.
# electrons in an atom is equal to its atomic number.
Solution:
In CO2, there are one carbon and two oxygen atoms and the number of electrons in them are:
In C ------> 6 electrons
In two O's -------> 2 x 8 electrons
Total in CO2 -------> 6 + (2 x 8) = 22 electrons.

The total number of electrons in one molecule is carbon dioxide isa)22...
The total number of electrons in one molecule of carbon dioxide (CO2) can be determined by adding up the individual electrons in each atom of carbon and oxygen.
1. Carbon atom:
The atomic number of carbon is 6, which means it has 6 electrons in its neutral state. Electrons are distributed in different energy levels or orbitals around the nucleus. The first energy level can hold a maximum of 2 electrons, while the second energy level can hold a maximum of 8 electrons. Carbon has its 2 electrons in the first energy level and the remaining 4 electrons in the second energy level.
2. Oxygen atoms:
The atomic number of oxygen is 8, indicating that it has 8 electrons in its neutral state. Similar to carbon, oxygen has its 2 electrons in the first energy level and the remaining 6 electrons in the second energy level.
3. Calculation:
In carbon dioxide (CO2), there is one carbon atom and two oxygen atoms. Therefore, we need to add up the electrons from each atom.
Carbon atom: 6 electrons
Oxygen atom 1: 8 electrons
Oxygen atom 2: 8 electrons
Total number of electrons = 6 + 8 + 8 = 22 electrons
Therefore, the correct answer is option 'A' - 22 electrons.
