Chapter 3 - Periodic Table Flashcards
State one way of sorting elements in the periodic table
One separation is metals and non metals
What are the typical properties of a metal
Good conductor of heat Good conductor of electricity High density Sonorous Shiny Ductile Mallebale
What are the features of a non metal
Poor conductor of heat Poor conductor of electricity Dull Not sonorous Brittle
Do metal s have high boiling points
Yes
Do non metal s have high boiling points
No
How many elements are there that exist naturally
92
What are the vertical columns in the periodic table called
Groups
What are the horizontal columns in the periodic table called
Periods
What is one way group one metals differ from other metals
Group one metals have lower boiling points than other metals
What are the group 1 metals
lithium (Li), sodium (Na), potassium (K), rubidium (Rb), cesium (Cs), and francium (Fr).
What happens to the group one boiling points as you go down the group
They decrease
Are group one metals highly reactive
Yes
Do the group one metal reactions get more vigouros going down the group
Yes
What do all group one metals produce when mixed with water
Hydrogen
What is one use of chlorine
Destroying deadly bacteria
What are the group 7 elements
fluorine, chlorine, bromine and iodine,
What happens to the melting points in group 7
They increase from top to bottom
What are group 7 elements also called
Halogens
What are group 7 s reactions with iron
Really vigouros , more vigouros from top to bottom
What are group 0 elements also called
Noble gasses
What are the 6 noble gasses
helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and the radioactive radon (Rn).
What does unreactive mean
Elements that take part in very little or no reactions
What is the pattern of boiling points in group 0
As the group goes down the boiling points get higher
