Explanation:

1 . periodicity  

   repeating nature of atomic structure

   Periodicity is the repeating nature or trend of an atom on the periodic table. Periodicity can be inform of ionization energy, atomic radius, nuclear charge etc.

2 . shell

     location of an electron

   Electrons are located in shells. It is where electrons are found in an atom and the probability of finding electrons there are high

3 . non-metals

     high ionization energies

    Non-metals have high ionization energies which is the energy required to remove a loosely bonded electron in an atom. Metals have low ionization energies.

4 . noble gases

       least reactive family

  Noble gases are called inert gases. They have complete electronic configuration and this makes them unreactive.

5 . neutral

       charge on a neutron

   Neutrons have no charge on them. They are subatomic particles found in the nucleus alongside the protons

6 . repel

         like charges

   Like charges repel one another

7 . attract

         unlike charges

  Unlike  charges attracts. Positve attracts negative charges.

why is arctic sea ice important? arctic sea ice keeps the polar regions cool and moderate global climate. sea ice has a bright surface; 80 percent of the sunlight that strikes it is reflected back into space. as sea ice melts in the summer, it exposes the dark ocean surface.
