What does the p mean in 1s22s22p63s! ?
o the p shell
o one of the 4 sub-shells
o always represents the outermost shell

its 1s2 2s2 2p6 3s2 3p6 , it goes in that order.

p represents the p orbital , which can accomodate a maximum of 6 electrons.

  the unit of the measure =

explanation:

  the property that is quantified by the energy needed per of material to raise the temperature by one.

  si unit of energy = joule (j)

  si unit of temperature = kelvin (k)

  si unit of mass of material = kilogram (kg)

the property that is quantified by the energy needed per of material to raise the temperature by one is called specific heat.

the unit of specific heat is
