QuestionAnswer
What is solubility? the ability of a substance to be dissolved by any liquid
What is the ability of a substance to be dissolved by any liquid? solubility
What is malleability? the property of a substance which allows it to be hammered into thin sheets(mostly metals are malleable)
What is the property of a substance to be hammered into thin sheets? malleability
(In order from top to bottom) In every box of the periodic table, there should be... Atomic number, Element's symbol, Element's name, Atomic mass
What is atomic number? the total number of protons in the nucleus of an atom
What is element/chemical symbol? the 1 or 2 letter representation of an element
What is the total number of protons in the nucleus of an atom? atomic number
What is the 1 or 2 letter representation of an element? element/chemical symbol
Elements in which 2 families are only found in their pure state because of their high reactivity? Family/Group 1(Alkali Metals) and Family/Group 2(Alkaline Earth Metals)
What is special about elements in family 1 and 2? They are only found as compounds, never in pure state.
What are the 4 specially named metals? Family 1 (Alkali Metals)), Family 2(Alkaline Earth Metals), Family 17 (Halogen Family), and Group 18(Noble Gases/Inert Gases)
What is true about the valence electron count and reactivity of elements in group 1? They all have 1 valence electron and are the most reactive group/family in the table.
What is true about valence electron count and reactivity of elements in group 17? There are 7 valence electrons and they are the most reactive group of nonmetals.
What is the most reactive metal in the entire table and in which family is it? Fluorine is the most reactive metal in the entire table and it is on the top of family 17.
What is true about the valence electron count and reactivity of elements in group 18? They have 8 valence electrons and they're stable. They generally do not form compounds.
How many gases are in their pure state in group 18 and why? 5/6 gases in Group 18 are in their pure state because they are stable.
What is an element that comes in different forms? **Allotrope/isotope
What are examples of physical properties? color, odor, state, solubility, malleability
What is color, odor, state, solubility, and malleability examples of? physical properties
Where are nonmetals located? Nonmetals are found to the right of the staircase.
Where are metals located? Metals are found to the left of the staircase.
What is fount to the right of the staircase? nonmetals
What is found to the left of the staircase? metals
Who was Dmitri Mendeleev? The Russian scientist who was given credit for the periodic table because he put blanks for elements that had yet to be discovered and predicted fairly accurate properties and weights of them.
Who was the Russian scientist who was given credit for the periodic table because he put blanks for elements that had yet to be discovered and predicted fairly accurate properties and weights of them? Dmitri Mendeleev
How did Dmitri Mendeleev arrange his table? By increasing atomic mass
Who arranged his table by increasing atomic mass? Dmitri Mendeleev and Lothar Meyer
How is the Periodic Table arranged today? By increasing atomic number
Who was Lothar Meyer? A German scientist who worked on and created the periodic table 5 years before Mendeleev. He arranged his table by increasing atomic mass but wasn't given credit because he did not predict the properties and weights of new elements like Mendeleev.
Who was a German scientist who worked on and created the periodic table 5 years before Mendeleev and arranged his table by increasing atomic mass but wasn't given credit because he did not predict the properties and weights of new elements like Mendeleev? Lothar Meyer
What are vertical columns called? Groups/families
What are groups/families? vertical columns
What is an example of an allotrope? graphite, charcoal, and diamond are allotropes of carbon
What are "groups"? the general whole. Ex: transition metals
What are groups? vertical columns. Synonym-family (Ex: group 17 or halogen family)
What are periods? the horizontal rows of elements
What are the horizontal rows of elements? periods
What is Group 1 of the periodic table? Alkali Metals
What is Group 2 of the periodic table? Alkaline Earth Metals
What group number is alkali metals? Group 1
What group number is Alkaline Earth Metals? Group 2
What is atomic mass-atomic number= total number of neutrons in the nucleus of an atom
What is atomic number? the total number of protons in the nucleus of an atom
What are nucleons? important sub-atomic particles AKA: protons and neutrons
What is the total number of protons in the nucleus of the atom? atomic number
What is the total number of protons and neutrons in the nucleus of an atom? atomic mass/nucleons
What are Family 17 elements called? Halogen Family
What group is the Halogen family? Group 17
What are Family 18 elements called? noble/inert gases
What group are the noble/inert gases? Group 18
Why are Group 18 elements called the noble gases? Family 18's elements are called the noble gases because they do not interact with each other much like royalty.
Which two words are synonyms? Family and group
What are the large "group" of elements at the center of the table called? transition metals
What are transition metals? the large "group" of elements at the center of the table
What are elements at the border of the staircase? metalloids/semimetals
What are metalloids? elements at the border of the staircase that have properties of metals and nonmetals
What are elements toward the bottom of the periodic table? rare earth metals. They are rarely found and found in the earth.
What is atomic mass? the total number of protons and neutrons in the nucleus of an atom OR the total number of nucleons.
Who made the change in the periodic table from arranging the table by increasing atomic mass to increasing atomic number and when? Henry Moseley in 1913
Who was Henry Moseley? A person who made the change in the periodic table from arranging the table by increasing atomic mass to increasing atomic number in 1913
What is an alloy? A physical mixture of 2 or more metals
What is an example of an alloy? Ex: Bronze is an alloy consisting primarily of copper, usually with tin.
How many periods are in the periodic table? 7 periods
How many families/groups are in the periodic table? 18 families/groups
