Electrons:
To determine the total number of electrons in a sucrose molecule, we simply add the number of electrons contributed by each atom:
- Each carbon atom has 6 electrons, so 12 carbon atoms contribute a total of 12 * 6 = 72 electrons.
- Each hydrogen atom has 1 electron, so 22 hydrogen atoms contribute a total of 22 * 1 = 22 electrons.
- Each oxygen atom has 8 electrons, so 11 oxygen atoms contribute a total of 11 * 8 = 88 electrons.
Therefore, a molecule of sucrose has a total of 72 + 22 + 88 = 182 electrons.
Protons:
The number of protons in a molecule is equal to the total number of protons contributed by each atom. Since each atom has a specific number of protons, we can calculate the total number of protons as follows:
- Each carbon atom has 6 protons, so 12 carbon atoms contribute a total of 12 * 6 = 72 protons.
- Each hydrogen atom has 1 proton, so 22 hydrogen atoms contribute a total of 22 * 1 = 22 protons.
- Each oxygen atom has 8 protons, so 11 oxygen atoms contribute a total of 11 * 8 = 88 protons.
Therefore, a molecule of sucrose has a total of 72 + 22 + 88 = 182 protons.
Neutrons:
Calculating the total number of neutrons in a sucrose molecule requires knowing the number of neutrons in each atom. Since the number of neutrons can vary depending on the specific isotope of an element, we will use average atomic masses to estimate the total neutron count:
- Carbon has an average atomic mass of approximately 12 atomic mass units (amu), of which about 6 are attributed to protons. Therefore, each carbon atom contributes an average of 12 - 6 = 6 neutrons. With 12 carbon atoms, the total neutron contribution from carbon is 12 * 6 = 72 neutrons.
- Hydrogen has an average atomic mass of approximately 1 amu, which is almost entirely attributed to a single proton. Therefore, each hydrogen atom contributes an average of 1 - 1 = 0 neutrons. With 22 hydrogen atoms, the total neutron contribution from hydrogen is 22 * 0 = 0 neutrons.
- Oxygen has an average atomic mass of approximately 16 amu, of which about 8 are attributed to protons. Therefore, each oxygen atom contributes an average of 16 - 8 = 8 neutrons. With 11 oxygen atoms, the total neutron contribution from oxygen is 11 * 8 = 88 neutrons.
Therefore, a molecule of sucrose has an estimated total of 72 + 0 + 88 = 160 neutrons.
In summary, a molecule of table sugar (sucrose) has a total of 182 electrons, 182 protons, and 160 neutrons.
