They are important because they determine if an element is radioactive]]> 2016-10-18 19:57:35 UTC https://padlet.com/32596/hhd17w52fdu1/wish/131624898 32596 https://padlet.com/32596/hhd17w52fdu1/wish/131651789 Each cloud or orbit surrounding each nucleus is called a shell.Each shell holds a maximum number of electrons.          
Level 1/K:2 electrons
Level 2/L:8 electrons
Level 3/M:18 electrons
Level 4/N:32 electrons]]> 2016-10-18 22:36:27 UTC https://padlet.com/32596/hhd17w52fdu1/wish/131651789 32596 https://padlet.com/32596/hhd17w52fdu1/wish/131664483 The squares of the periodic table are the names of different elements.]]> 2016-10-19 00:41:18 UTC https://padlet.com/32596/hhd17w52fdu1/wish/131664483 32596 https://padlet.com/32596/hhd17w52fdu1/wish/131665147 The periodic table of elements sorts the elements known to the world.It sorts these elements into three groups, Metals, Nonmetals, and Metalloids. The elements are also arranged by the order of the atomic number.The atomic number increases from left to right and down line by line.]]> 2016-10-19 00:47:01 UTC https://padlet.com/32596/hhd17w52fdu1/wish/131665147 32596 https://padlet.com/32596/hhd17w52fdu1/wish/131666328 Many substances are not made of just one atom.Atoms can form to make molecules.A molecule is the smallest thing of a substance that is made from more than one atom, but still has the properties of the substance.]]> 2016-10-19 00:57:36 UTC https://padlet.com/32596/hhd17w52fdu1/wish/131666328 32596 https://padlet.com/32596/hhd17w52fdu1/wish/131667894 Each element are made up of one atom. This atom has a special number of protons. Elements set of protons, neutrons, and electrons give the element it's properties. the scientists use these properties to place it into the three groups : metals, nonmetals, and metalloids.]]> 2016-10-19 01:09:38 UTC https://padlet.com/32596/hhd17w52fdu1/wish/131667894 32596 https://padlet.com/32596/hhd17w52fdu1/wish/131670115 Each block holds great information about the element. You can look at the elements properties by just looking what area the block is. The atomic number shows that a chromium atom's nucleus has 24 protons. The color yellow tells that chromium is a metal. There is also a chemical symbol and the name of the element. ]]> 2016-10-19 01:25:17 UTC https://padlet.com/32596/hhd17w52fdu1/wish/131670115 32596 https://padlet.com/32596/hhd17w52fdu1/wish/131873242 The periodic table has 18 columns. each column is called a group or family. Each row in the periodic table is a period.the first element in a period is very reactive. The last is inactive.]]> 2016-10-19 17:44:53 UTC https://padlet.com/32596/hhd17w52fdu1/wish/131873242 32596 https://padlet.com/32596/hhd17w52fdu1/wish/132124906 I had a lot of fun doing this  even though I didn't finish early.
