| Question | Answer |
|---|---|
| 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 |
