Periodic Trend is : the tendencies of certain elemental characteristics to increase or decrease as one progresses along a row or column of the periodic table of elements. Periodic Trend is : Periodic Trend is not : Periodic Trend is : the tendencies of certain elemental characteristics to increase or decrease as one progresses along a row or column of the periodic table of elements. Periodic Trend is : the tendencies of certain elemental characteristics to increase or decrease as one progresses along a row or column of the periodic table of elements. Periodic Trend is : Proton is : Gives the identity of the atom; found at the top of the element box. Proton is : Proton is not : Proton is : Gives the identity of the atom; found at the top of the element box. Proton is : Gives the identity of the atom; found at the top of the element box. Proton is : Reactivity is: the tendency of a substance to undergo chemical reaction, either by itself or with other materials, and to release energy Reactivity is: the tendency of a substance to undergo chemical reaction, either by itself or with other materials, and to release energy Reactivity is: the tendency of a substance to undergo chemical reaction, either by itself or with other materials, and to release energy Reactivity is: Metals are: an element, compound, or alloy that is a good conductor of both electricity and heat. Metals are usually malleable, ductile and shiny Metals are: Metals are not: Metals are: an element, compound, or alloy that is a good conductor of both electricity and heat. Metals are usually malleable, ductile and shiny Metals are: an element, compound, or alloy that is a good conductor of both electricity and heat. Metals are usually malleable, ductile and shiny Metals are : Periods are : a series of rows, left to right, same number of electron shells DONT WRITE!!!! Every element in the top row (the first period) has one orbital for its electrons. All of the elements in the second row (the second period) have two orbitals for their electrons. It goes down the periodic table like that. At this time, the maximum number of electron orbitals or electron shells for any element is seven.

At this time, the maximum number of electron orbitals or electron shells for any element is seven. Periods are : elements that have the same number of electrons in their outer orbital valence electrons DONT WRITE> Every element in the first column (group one) has one electron in its outer shell. Every element in the second column (group two) has two electrons in the outer shell. As you keep counting the columns, you'll know how many electrons are in the outer shell. There are some exceptions to the order when you look at the transition elements. Transition elements start to add electrons to the second-to-last shell.

Groups/families are : Alkali metals are : DONT WRITE. Starting at the top we find hydrogen(H). But wait. That element is NOT in the family. When we told you about families, we said that they were groups of elements that react in similar ways. Hydrogen is a very special element of the periodic table and doesn't belong to any family. While hydrogen sits in Group I, it is NOT an alkali metal. very reactive; all have one electrons in outer shell, one electron away from being happy (full shells), malleable (bendable) and sometimes soft enough to be cut with a dull knife Alkali metals are : Alkali metals are not : Alkali metals are : DONT WRITE.
