What does the period
on the periodic table
show you?

A period in the periodic table is a row of chemical elements. All elements in a row have the same number of electron shells. Each next element in a period has one more proton and is less metallic than its predecessor.

Explanation:

Explanation:

it shows that how many Period number tells us how many electron shells, or orbits, or energy levels an element has. Nothing more. Elements are grouped (put into columns) on the periodic table according to their properties.

  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
