What Is A Medium When It Comes To Physics?

What is a medium when it comes to physics?

 

A medium, in relation to physics, is any substance that carries a wave, or is where a wave can travel through.

There are two ways to transport energy.

Electromagnetic waves are waves that dont require a medium. An example of an electromagnetic wave is light.

Mechanical waves are waves that require a medium like water or air. an example of a mechanical wave is sound.

Use The Periodic Table To Identify The Number Of Core Electrons And The Number Of Valence Electrons In Each Case Below., Potassium (K): 1s22s22p63s23p

Use the periodic table to identify the number of core electrons and the number of valence electrons in each case below. Potassium (K): 1s22s22p63s23p64s1 core electrons valence electrons   Potassium (K) has : core electrons : 18 valence electron : 1 Further explanation Valence electrons are electrons used in forming bonds and are in the outer shell of an element.   The main group elements usually use electrons in the subshell ns and np   While the transition elements in the subshell (n-1) d   The location of the elemental groups in the periodic system is determined by the number of valence electrons in the last sub-shell   The period of an element is determined from the valence shell (the biggest main quantum number (n))         Core electrons are electrons that belong to atoms except for valence electrons. It is located close to the core and fills the inner shell.   Electron configurations from K :Ar 4s¹ or 1s²2s²2p⁶3s²3p⁶ 4s¹ From this electron configuration , number ...
