What is the advantage of using the electromagnetic spectrum model?

The electromagnetic model can be used for the transmission of long or short radio waves. they are also used in for electromagnetic waves.

Explanation:

Electromagnetic Spectrum model: refers to the entire range  frequencies or wavelengths  of electromagnetic radiation  expanding he longest radio waves to  gamma rays and  visible light.

The advantage of using the electromagnetic spectrum model is as follows:

They are also known as EM radiation or protons and electromagnetic lights

They are used for electromagnetic waves.

They are used to transmit long or short or FM wavelength radio waves.

They are used to in transmitting a telephone or wireless signals or Television and energies.

They help the body in small quantity to produce vitamin D

Almost all wavelengths and frequencies  of electromagnetic radiation can be used for spectroscopy.

you need to take a look at the periodic system in order to sort these elements into pairs that would most likely exhibit similar chemical properties. first, you need to find elements that are found in the same group (groups are vertical in the periodic system), and then to see whether they have the same valence number. if they meet these criteria, they will have similar properties.

the first pair: ne (neon) and kr (krypton), are noble gases found in group 8

the second pair: li (lithium) and k (potassium), found in group 1

the third pair: s (sulfur) and te (tellurium), found in group 6
