What is the charge on the ion formed by Na?
A
-1
B
0
C
+2
D
+1
Verified step by step guidance1
Identify the element in question, which is sodium (Na). Sodium is an alkali metal located in Group 1 of the periodic table.
Recall that elements in Group 1 typically lose one electron to achieve a stable electron configuration similar to the nearest noble gas.
When sodium loses one electron, it forms a cation with a positive charge because it now has more protons than electrons.
The charge on the sodium ion is therefore +1, represented as Na\textsuperscript{+}.
Confirm that the options given include +1, which matches the expected charge for the sodium ion.
