Which type of change occurs when the electrons between two atoms form a bond?

a.
neutron change

b.
nuclear change

c.
color change

d.
chemical change

I think the correct answer from the choices listed above is option D. The type of change that occurs when the electrons between two atoms form a bond would be a chemical change. The new bond formed entails that a new substance is formed with a whole new properties which is a characteristic for a chemical change.

Determine the  wavelength of light emitted when an electron  in an li2+ ion  makes a transition from an orbital with n  =  6 to an orbital with n  = 5.
