Answer:
metal atoms lose electrons to form positively charged ions. non-metal atoms gain electrons to form negatively charged ions
Answer:
As a wavelength increases in size, its frequency and energy (E) decrease. From these equations you may realize that as the frequency increases, the wavelength gets shorter. As the frequency decreases, the wavelength gets longer.
