Science Flashcards
Why. It’s a periodic table important
Help keep things organized and neat
How is the current periodic table organized
The almonds are put in row increasing by atomic number.
What are the three main categories of the periodic table
Metal
Nonmetals
Metalloide
Metals are conductors of
Electricity and energy
One chemical property for metal
Rust. Dorrosion
That’s one thing at a property or nonmetal
Dull. Easy
Let’s for physical properties of metals
Shiny ductile dense Maliable
Compare and contrast physical properties of nonmetals
One shiney and the other are mostly not
They are non-metal Found in
Gases
Let’s do physical properties of metalloids
Dull and shiny
Compare metals to metalloids
Metalloids Are not conductor Electricity
Row and Periods Begin with what type of metal
Alkali
Rows and periods And with what type of element
Noble gases
Group are also called
Family
Alkali Medals react by me Violently with what Substance?
Are they found for your nature
WateR
No
How many valence Electrons are found in alkaline. Earth metals
2
What metals are good conductors of heat and electricity
Transition metal
Which group has seven valence. Electrons and are never found in nature
2
Which group makes up the earths atmosphere
Noble gases
Which group of elements are mostly synthetic. Or man made
Rare earth elements
Chemical properties describe
the behavior of substance as it becomes new substance
Physical properties describe
A characteristic or desperation of a substance that may help you identify it
Has elements that are bonded to make different substance
Compound
Elements that aren’t bonded together
Mixture
