Question
Explain how the charge on a sodium ion (Na+) is linked to electron loss.
Answer
The charge on a sodium ion (Na+) is +1 because it loses one electron from its outer shell. This loss of an electron results in a positively charged ion, as there are now more protons than electrons in the atom.
Explanation
This question tests the understanding of how electron loss leads to the formation of positive ions. It requires the student to connect the concept of electron transfer to the resulting charge of the ion.
Common mistake
Misunderstanding Ion Charges
Students often confuse the charge of a simple ion with the number of electrons lost or gained, thinking that the charge is simply the number of electrons involved.
Emphasize that the charge on a simple ion is determined by the loss of electrons for positive ions and the gain of electrons for negative ions, and that it reflects the difference between protons and electrons.
