Question
Answer

🗑
show an element's atomic number  
🗑
Elements within the same group have the same number of _________.   show
🗑
The process of losing or gaining electrons is called _________.   show
🗑
show semiconductors  
🗑
If elements belong to the same family, they often have a similar ___________.   show
🗑
Where are alkali metals located on the periodic table?   show
🗑
show noble gases  
🗑
Why are Group 18 noble gases relatively inert?   show
🗑
Silicon is not a semiconductor. True or False   show
🗑
show He predicted new elements.  
🗑
In the modern periodic table, elements appear at regular intervals if they have similar ________.   show
🗑
A group's elements react similarly because of their ______________.   show
🗑
When an element's outermost energy levels are only partially filled, some elements are highly _______.   show
🗑
show metals  
🗑
Elements in a family in the periodic table have similar _____ and _______ properties.   show
🗑
show transaction metals  
🗑
What Group do noble gases belong to?   show
🗑
What is the name of elements that can conduct heat and electricity under certain conditions?   show
🗑
When Mendeleev studied the properties of the elements, what was he looking for?   show
🗑
As you move from left to right across a period in the modern periodic table, what do you notice about the elements?   show
🗑
show less reactive atom  
🗑
Metals tend to be good conductors of heat. True or False?   show
🗑
Because Alkali metals have one valence electron that is easily removed to form a positive ion, they are extremely _____.   show
🗑
show by gaining an electron to form a negative ion  
🗑
show losing electrons to form positive ions  
🗑
Computers use a semiconductor ___________.   show
🗑
When properties were repeated in Mendeleev's periodic table, he started a new ___.   show
🗑
What does the periodic law state?   show
🗑
Which property, chemical or physical, is determined by the number of valence electrons?   show
🗑
show insulators  
🗑
Metals are divided into 3 families based on the number of ______ they have.   show
🗑
show Alkali Metals  
🗑
show valence electrons  
🗑
show semiconductors or metalloids  
🗑
show Metals are easily shaped and drawn into wires. Nonmetals aren't malleable or ductile. Metals are also shiny.  
🗑
show It is used to organize the elements by atomic number and properties. They can easily find elements with similar physical and chemical properties because they are in the same group or family.  
🗑
show No. They are somewhat-but not entirely-like metals. Metals can conduct heat and electricity. Under certain circumstances, semiconductors can but not always.  
🗑
show Atom=smallest unit of an element Molecule=consists of 2 or more atoms  
🗑
What is the definition of an ion?   show
🗑
What type of charges do a cation and an anion have?   show
🗑
Identify some examples of transition metals and their uses.   show
🗑
show They have the same valence electrons (7) and similar chemical properties.  
🗑
Differentiate alkali metals and alkaline-earth metals. Identify ways each are used.   show
🗑
show conductors  
🗑


   

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
 
To hide a column, click on the column name.
 
To hide the entire table, click on the "Hide All" button.
 
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
 
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
