What is the energy of the electron in a helium ion with a charge of +1 in an orbit with a value of n=4? Use k=2.179×10^−18 J.
Report your answer with three significant figures.

answer

the ions in solute supperate from eachouthere

weight of any object is given by

w = m*g

where m is mass of the object and g is the acceleration due to gravity.

for earth the value of g is 9.8 m/s^2 so

w=117.6 n m=12 g=?

117.6=12g => g=9.8 m/s^2

which is the force of gravity on earth.
