Periodic Table
Where on the element square does it tell you the type of element? (Metals, metalloids, nonmetals, etc)
Bottom right
Nuclear charge
What are valence electrons? How can you find it?
Valence electrons are electrons in the highest energy level. You can look at them by looking at the column # on the periodic table
What type of metal is often used in batteries and can burn through concrete wall?
Lithium
What element is used as currency today?
Gold
Bigger
How many valence electrons do the noble gases have?
8
Why are noble gases called noble?
They don't interact with other elements, have low reactivity
What type of element is most abundant on the periodic table?
Metals
Ionization energy increases / decreases from left to right
increases
How many valence electrons are there for sulfur
6
What element is the backbone for many living things?
Carbon
Electronegativity increases/decreases from top to bottom
decreases
How many valence electrons are there for Chlorine
7
What precious metal is shiny, but often tarnishes when exposed to air
What does the gray symbol on an element square mean?
State of matter is unknown
As you move left to right on the periodic table elements get more / less metallic
Less
how many electrons are either gained, lost or shared in chemical bonding and reactions
Where are many precious metals (ex: Rhodium, palladium) found in?
Meteorite rock
