These metals are less reactive than groups 1 and 2.]]> 2016-04-05 19:13:08 UTC https://padlet.com/2018juliana00/sm4augqoig24/wish/104223667 2018juliana00 https://padlet.com/2018juliana00/sm4augqoig24/wish/104223771 The Carbon group has 1 nonmetal 2 metalloid and 3 metals. It has 4 electrons on the outer level and its reactivity depends on the element. Carbon in the Carbon group is found uncombined and is used to make compounds such as proteins, fats, and carbohydrates.

It has 6 electrons in the outer level. It is also reactive. 20% of our air is oxygen and oxygen helps stuff burn. ]]> 2016-04-05 19:13:35 UTC https://padlet.com/2018juliana00/sm4augqoig24/wish/104223804 2018juliana00 https://padlet.com/2018juliana00/sm4augqoig24/wish/104223885 Noble gases have nonmetals and have 8 electrons in the outer level. These elements cannot gain or loose electrons. ]]> 2016-04-05 19:13:55 UTC https://padlet.com/2018juliana00/sm4augqoig24/wish/104223885 2018juliana00 https://padlet.com/2018juliana00/sm4augqoig24/wish/104223952 A period means regular repeating.

These metals are a little less reactive than group 1. Alkaline Earth Metals have 2 electrons in the outer level shell. This makes it harder for there electrons to combine]]> 2016-04-06 16:38:42 UTC https://padlet.com/2018juliana00/sm4augqoig24/wish/104407825 2018juliana00 https://padlet.com/2018juliana00/sm4augqoig24/wish/104408166 Lanthanides are metals at the bottom of the periodic table of elements and are shiny reactive metals. ]]> 2016-04-06 16:39:57 UTC https://padlet.com/2018juliana00/sm4augqoig24/wish/104408166 2018juliana00 https://padlet.com/2018juliana00/sm4augqoig24/wish/104408460 The Boron group has 1 metalloid and 5 metals they have 3 electrons in the outer shell. It is reactive. One common element is aluminum. ]]> 2016-04-06 16:40:50 UTC https://padlet.com/2018juliana00/sm4augqoig24/wish/104408460 2018juliana00 https://padlet.com/2018juliana00/sm4augqoig24/wish/104408539 The Nitrogen group has 2 nonmetals, 2 metals, and 2 metalloids. It has 5 electrons in the outer level. Its reactivity depends on on the element. Nitrogen is in the air and is 80% of the air we breathe. ]]> 2016-04-06 16:41:04 UTC https://padlet.com/2018juliana00/sm4augqoig24/wish/104408539 2018juliana00 https://padlet.com/2018juliana00/sm4augqoig24/wish/104408582 Halogens have nonmetals and has 7 electrons in the outer level. It is also very reactive. Halogens are missing one electron so it combines with the Alkali Metals to be complete. This makes salt. ]]> 2016-04-06 16:41:12 UTC https://padlet.com/2018juliana00/sm4augqoig24/wish/104408582
