Question

What is the charge on the potassium ion?

Select one:

a.
1 +


b.
1 -


c.
2 -


d.
2 +

Answer 1

a.) 1+

Step-by-step explanation:

Potassium (K) is located in the first column of the periodic table.

These elements have 1 valence electron. As such, in order to obtain a full octet (8 valence electrons), these elements are likely to lose 1 electron. When this occurs, the element gains an overall charge of 1+ because the positively-charged protons now outnumber the negatively-charged electrons by 1.
