When forming a compound, sodium loses electrons. What is the resulting charge on the sodium ion?
A
+2
B
0
C
+1
D
-1
Verified step by step guidance1
Understand that when an atom loses electrons, it becomes a positively charged ion called a cation.
Recall that sodium (Na) has one electron in its outermost shell (valence electron).
When sodium loses this one valence electron, it has one more proton than electrons, resulting in a positive charge.
The charge on the sodium ion is equal to the number of electrons lost, which is +1 in this case.
Therefore, the sodium ion formed has a charge of +1, often written as Na\^{+}.
