Which of the following correctly describes the "sea of electrons" that forms metallic bonds? - metals lose electrons to nonmetals
- metals pass electrons
around from one metal atom to another metal atom
- metal atoms lose one electron at a time until they are all gone
- metals have an unending ability to take electrons away from other materials

in scientific notation, the value of the  speed of light in a vacuum

  will be written as 2.995 * 10^8. when this value is represented in the form of

  a * 10^b, then, a = 2.995 and b = 8.

the value of the speed of light in a vacuum given above can also be rounded up to approximately 300000000. in this case, the scientific notation will be written as 3 *10^8.

atomic mass = 39

number of neutrons = 20

number of protons= 19

electronic configuration = 1s2 2s2 2p6 3s2 3p6 4s1

the number of electron in first shell = 2

number of electrons in n=3 shell = 8
