Physics
1 answer:
anzhelika [568]3 years ago
3 0

Answer:

1⁺ ion

Explanation:

Metals in the first group on the periodic table will prefer to form 1⁺ ion. This is because the 1 valence electron in their orbital.

Most metals are electropositive and would prefer to lose electrons than to gain it.

Like all metals, the group 1 elements called the alkali metals would prefer to lose and electron.

On losing an electron the number of protons is then greater than the number of electrons. This leaves a net positive charge.

Which example is NOT a part of the electromagnetic spectrum?
Alekssandra [29.7K]

Electricity is NOT a part of electromagnetic spectrum.

An electromagnetic spectrum contains electromagnetic radiations arranged according to frequencies and wavelength.

<h2>Further Explanation </h2><h3>Electromagnetic waves  </h3>
  • Electromagnetic waves are types of waves that do not require a material medium for transmission.
  • These waves are mostly transverse in nature, which means the direction of transmission is perpendicular to the direction of vibration of particles.
  • They include, light waves, radio waves, x-rays, infra-red, etc.
<h3>Electromagnetic spectrum </h3>
  • An electromagnetic wave shows electromagnetic waves arranged according to frequencies and wavelength.  
  • Electromagnetic spectrum contains electromagnetic waves: Gamma rays, x-rays, Ultraviolet, Visible light, infra-red, microwaves, and radio waves.
  • The electromagnetic spectrum is divided into various sections based on wavelength, with gamma rays having the shortest wavelength and radio waves having the longest wavelength.
  • The part of the electromagnetic spectrum that we can see using our naked eyes is called the visible light spectrum.
  • In order of frequency, the radio waves have the lowest frequency while gamma rays have the largest frequency.
<h3>General characteristics of electromagnetic waves  </h3>
  • They travel with the speed of light (3.0 x 10^8 m/s)
  • They possess energy that is given by; E =hf, where h is the plank’s constant and f is the frequency.
  • They are transverse in nature, and therefore, the wavelength is measured between successful crests or troughs.
  • They can travel through vacuum

Keywords: Electromagnetic spectrum, electromagnetic waves.
