Using the Bohr model, determine the lowest possible energy, in joules, for the electron in the Li2+ ion.

E = - 19.611× J

Explanation: The lowest possible energy can be calculated using the formula:

where:

Z is atomic number of the atom;

k is a constant which contains other constants and is 2.179× J

n is a layer;

For the lowest possible, n=1.

Atom of Lithium has atomic number of Z=3

Substituing:

J

The energy for the electron in the ion is - 19.611 joules

for step 7 table c on the lab "newtons law of action"   the average time it took the car to travel .25 meters   was 1.92 seconds.

the average time it took the car to travel 0.50 meters was 2.61 seconds

hope this : )
