nasu said:z is the charge of the nucleus and is not 1 for Li.
For the rest, it may help to post the complete text of the problem.
Yes.physicsnobrain said:IF the question is instead: In the equation for the bohr model of the atom, what is the z value for Li2+ ion?
Does this make more sense?
DrClaude said:Yes.
physicsnobrain said:Well isn't there still three unknown variables Energy and n value and z value?
You had the right equation in the OP. Go back in your notes/textbook and find what the ##Z## stands for.physicsnobrain said:The question exactly as it appears word for word is: In the equation for the Bohr model of the atom, what is the Z value for Li2+ ion?
I am still unsure of how to go about this question. Which equation should I use?

A physical change is a change in the physical properties of a substance, such as shape, size, or state of matter, without altering its chemical composition. A chemical change, on the other hand, results in the formation of a new substance with different chemical properties.
An atom is the smallest unit of matter that retains the chemical properties of an element. It is made up of a nucleus containing protons and neutrons, surrounded by electrons. A molecule, on the other hand, is a group of two or more atoms held together by chemical bonds.
Potential energy is the energy an object possesses due to its position or state, such as gravitational potential energy or chemical potential energy. Kinetic energy, on the other hand, is the energy an object possesses due to its motion. It is calculated as 1/2 times the mass of an object times its velocity squared.
Heat is the transfer of thermal energy from one object to another due to a difference in temperature. Temperature, on the other hand, is a measure of the average kinetic energy of the particles in a substance. It is measured in degrees Fahrenheit, Celsius, or Kelvin.
A conductor is a material that allows electricity or heat to flow through it easily. Metals are good conductors due to the presence of free electrons. An insulator, on the other hand, is a material that does not allow electricity or heat to flow through it easily. Examples include rubber, plastic, and glass.
