The Periodic Table

1) What conclusions can be drawn about the relationship between the arrangement of elements on the periodic table and the patterns observed in their properties?

:Properties of elements are related to atomic numbers.***
:Properties of elements are related to ductility.
:Properties of elements are related to malleability.
:Properties of elements are related to luster.

2) Which physical properties are characteristic of metals? Choose all that apply.

:Brittle.
:High luster.***
:Malleable.***
:Ductile.***
:Not very reactive.

3) By looking at the periodic table, Juan finds the following information for rubidium.

How many protons does a rubidium atom have? Use the table above to answer the question.

:37.***
:48.
:85.
:122.

4. How can you describe the location of vanadium (V, atomic number 23) on the periodic table? Choose all that apply.

:Period 5, group 4.
:Period 4, group 5.***
:Lanthanide series.
:Nonmetals.
:Transition metals.***

5) What is true about the element calcium (Ca, atomic number 20)? Choose all that apply.

:It has 2 valence electrons.***
:It has 4 valence electrons.
:It is a nonmetal.
:It is reactive.***
:It is a metal.***

  1. I don't like any of the choices for question #1 but you've probably picked the best answer of the lot. (But it isn't anything to brag about. :-(
    I agree with all of the others. Good work.

  12. similar-behaving elements are in the same vertical column, and the properties that they share vary repeatably as you move down the columns. If the unknown substance is a shiny solid, odds are it's a metal. If the unknown substance fizzes, pops, or explodes in water, odds are it comes from column 1 or 2. If it's a non-reactive gas, it's a noble gas (column 18) If it's a crumbly, dull, brittle solid, it's a non-metal The real usefulness of the periodic table is in its predictive abilities, not just the list of information that may be contained in each square.

  23. Pls, do not put the answers on this website, this should be a basis for learning and not cheating. This is not what this site was created for and it doesn't deserve to be mistreated. Please, FIND THE ANSWERS ON YOUR OWN. I come here to help find an explanation to questions i need help with, not to have the answers given to me, because you are not learning the information because as soon as you need to answer a question on i-step, what do you think is going to happen? Do you think you can turn to Jiskha? No, that is when you will need to KNOW the information. I know this is your choice, but make sure you know you are making the right one.
