It's a Group Thing
Mixed Nuts
100
Which family contains the most reactive metals on the periodic table?
The Alkali Metals are the most reactive metals.
100
How many rows are there in the periodic table?
Seven (7)
100
Which type of element makes up the majority of the periodic table, metals, nonmetals or metalloids?
The metals make up 2/3 of the periodic table.
100
How many columns (groups) are there on the Periodic Table?
Eighteen (18)
100
Who is considered to have constructed the first table charting the elements?
Dimitri Mendeleev
200
What family does an element with 2 valence electrons belong to?
The Alkaline Earth Metals.
200
Are elements with similar valence electron configurations located in the same group or in the same period?
Elements with the same number of valence electrons are in the same group.
200
Are boron, silicon and tellurium metals, nonmetal, or metalloids?
They are metalloids.
200
Halogens form compounds by doing what to an electron forming an ion.
What is gaining an electron?
200
Who reorganized the periodic table by placing the elements in order based upon their atomic numbers?
Henry Mosley
300
Which family is composed of all the common metals?
The transition metals
300
What order is the modern periodic table in?
Increasing atomic number.
300
Where is the approximate dividing line between metals and nonmetals?
The stair step line divides the metals from the nonmetals.
300
Which family is most likely to form ions that will have a +3 charge?
Group 13 will produce ions with a +3 charge because they have 3 valence electrons.
300
An element with both metallic and nonmetallic properties is called what?
Metalloids have both metallic and nonmetallic properties.
400
Which family on the periodic table is used for killing germs?
Group 17 the Halogens kill germs.
400
As you move down the periodic table this happens to the atomic number.
What is it increases?
400
Explain why metals are commonly used for electrical wiring and piping for heating. Make sure to list at least 3 physical properties to back up your answer.
Metals are malleable (can be flattened), ductile (can be drawn into wire), and are good conductors of heat and electricity.
400
These are the most reactive nonmetals.
What is halogens?
400
The electrons that are on the outside energy level, and are available to be lost, gained or shared are called
valence electrons
500
Using their atomic structure, explain why the Noble Gases are unreactive and do not form ions.
Noble Gas elements have a completely filled valence shell of 8 electrons (2 in He) this is why they are unreactive and do not form ions.
500
A column on the periodic table is called this.
What is a group?
500
Metallic properties tend to increase in which direction on the periodic table: left to right or right to left? Give one reason using the setup of the periodic table to back up your answer.
Metallic properties increase right to left across a period because metals begin every period and nonmetals end every period.
500
Mendeleev created a new row in his periodic table when this repeated.
What is chemical properties?
500
Lithium and sodium are never found in nature as pure elements. They are always combined with other substances. Explain why this is so.
Lithium and sodium are highly reactive group 1 metals and easily give up electrons to combine with other elements.
