what is the most common ion charge for lithium, li?\n+1\n+2\n-1\n-2
Answer
Explanation:
Step1: Recall lithium's position in periodic table
Lithium is in Group 1.
Step2: Determine ion - formation behavior
Elements in Group 1 lose 1 electron to achieve a stable electron configuration.
Step3: Calculate ion charge
Losing 1 electron gives a + 1 charge.
Answer:
+1
