You get 8 groups in the periodic table: 1,2,3,4,5,6,7 and 0 (8)

Each group represents the amount of electrons the element has on its outer shell. For example group 2 elements, will have 2 electrons on their outer shell.

Group 0 (or 8) dont react and that is because they have a full shell of 8 electrons.
In contast to this, group 1 elements are the most reactive elements in the whole periodic table. Think about this, the less electrons there are in the outer shell (for this case in group one 1) then the more they will want to be with their friends so they get angry and become so reactive! Of course, if there is a full shell, like in group 0 (8) also known as the noble gasses, then the elements are happy as theyre with their friends so thats why they dont react.

The more shells an element has, the more the electron (s) on the outer shell are away from the nuclous which reduces the energy level.
Pottasium is a very reactive metal in group 1 and has 3 shells.

Answer from: Quest

the tides are influenced by both the moon and the sun, it's easy to see that when the sun lines up with the moon and the earth, as during a new moon or full moon, the tidal effect is increased. these are known as spring tides, named not for the season, but for the fact that the water "springs" higher than normal. on the other hand, if the sun and the moon are 90 degrees apart in relation to an observer on earth as during the first quarter moon or third quarter moon, then high tides are not as high as they normally would be. this is because despite its greater distance, the sun's mass allows it to exert enough gravitational force on the oceans that it can negate some of the effects of the moon's pull. this phenomenon of lower high tides is called a neap tide. if you need more information on this topic visit moonconnection.com.
