Explanation:
a potassium ion has a charge of 1+.
Magnesium is in the second column and therefore has 2 electrons in its outermost shell. It would tend to lose two electrons and form a +2 ion. Potassium is in the first column and therefore has 1 electron in its outermost shell. It would tend to lose one electron and form a +1 ion.

Answer:
The work done is
Explanation:
1. Define the formula of work.
In this case the work (W) done is the result of add up the kinetic energy and the potential energy , and subtract them at the initial and final states:
Replacing expressions:
In the initial state at the bottom of the stairs both kinetic and potential energy are equal to zero, because kinetic energy depends on velocity and her initial velocity is zero, and potential energy depends on height and her initial height is zero too.
So the work done is defined by:
(Eq.1)
2. Calculate the height:
The height of the stairs is 19m
3. Convert the mass of the woman from lbs to kg:
The woman heights 61kg
4. Replace values in (Eq.1):
Base on the said question or problem that state and ask to calculate the current of the said light bulb and in my further calculation and further analysis, I would say that the current of the light bulb would be 0.0292. I hope you are satisfied with my answer and feel free to ask for more
