Periodic Table (Tabat)

QuestionAnswer
What elements are the least reactive on the periodic table? Noble gases
Where would the most reactive metallic elements of the periodic table most likely be found? On the far left side of the table
Properties such as magnetism, luster and malleability have been used to group together which category of elements on the periodic table? Metals
What best describes the organization of the periodic table of the elements? Elements within a group have similar properties
What elements would have similar properties to those of potassium? Lithium and sodium
Which of the following elements, hydrogen, fluorine or lead would have 7 valence electrons? Fluorine
What is the significance of metalloids in the periodic table? They separate metals from nonmetals
What element in Period 3 is known to be a highly reactive metal? Sodium
If an element has no electrons to share and is stable, what family is it found in? Noble gases
Where would a new highly reactive metal most likely be placed on the periodic table? On the left side
How is the current periodic table arranged? By atomic number
What elements are shiny, malleable, ductile, and good conductors of heat and electricity? Metals
Which element is the most reactive - calcium, beryllium, strontium or magnesium? Strontium
Which element is described as a brittle, nonconductive solid - calcium, thorium, sulfur or sodium? Sulfur
How would you describe the purpose for the bold staircase line on the right side of the periodic table? Used to separate metals from nonmetals
What characteristics do the elements on the far right side of the periodic table have in common? They are found in elemental form in nature
What best describes elements found in a column of the periodic table? The elements have similar chemical properties
What property is unique for each element? The atomic number
What are the changes in the physical state of elements in PERIOD 4? From left to right - solid, liquid, gas
What property best supports the statement that a material can be identified by its behavior when chemically combined? Reactivity
How would you describe the reactivity of alkali metals? Reactivity increases down a group
What characteristics of an element determines it's placement in the periodic table? The number of protons
Which element is the least reactive - carbon, hydrogen, helium or iodine? Helium
Which group contains elements with the most varied properties? Transition metals
What is a property of metalloids? The ability to conduct electricity under certain conditions
What subatomic particles determine the reactivity of groups of elements in the periodic table? Electrons
What describes the reactivity of metals when moving left to right on the periodic table? They become less reactive
Why are alkali metals the most reactive group in the periodic table? They have only one electron in their outer energy level
Why does reactivity in nonmetals most likely increase from left to right in the periodic table? Attraction for electrons increases
Which element is a member of the halogen family - chlorine, sodium, oxygen or helium? Chlorine
If a scientist creates a new synthetic element where would the new element most likely be placed on the periodic table? Near the bottom
What can be determined about sodium based on its location on the periodic table? It is a solid metal at room temperature
Which would sink first when placed in water - silver, gold or copper. Gold
Which element is in the same family as chlorine and fluorine - hydrogen, bromine, oxygen or lithium? Bromine
What do the atomic numbers represent? Number of protons
What best describes groups 3 through group 12 of the periodic table? Transition metals
How is the periodic table used to identify properties of elements? By the group in which the elements are located

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.
