Going from left to right across the periodic table, the size of an element's atomic radius...
Increases
Decreases
Stays roughly the same
is randomized
What did Henry Mosley use to organize his periodic table?
Atomic number
Atomic mass
Atomic radius
physical properties
What does it mean to be a semiconductor in the metalloid family?
Sometimes acts like a metal element.
Normally don't conduct but will at high temperatures or when certain substances are added.
Don't transfer electrons normally but will during certain chemical reactions.
Almost always will join valence electrons to make a larger atom.
What did Dmitri Mendeleev use to organize his periodic table?
Atomic number
Chemical properties
Atomic mass
Physical properties
Which is NOT a physical property of a metal element?
left of the staircase
Brittle
malleable
good conductors of heat and electricity.
What category of element is the most common in the periodic table?
Gas
Nonmetal

What is the most stable and nonreactive group in the periodic table?
Noble Gases
Transition Metals
Actenides
Alkali Metals
How are the Metalloids unique?
They look like Metals
They are very reactive elements
They behave like nonmetals
Both A and C
What is the most stable and nonreactive group in the periodic table?
Alkali Metals
Actenides
Transition Metals
Noble Gases
What is the most reactive metal element?
Francium
Berillium
Fluorine
Hydrogen
What is the most reactive non metal element?
Francium
Fluorine
Sodium
Helium
Why are noble gases nonreactive
Because they have a full outer electron shell
Because of the shielding effect
Because of their high electronegativity
Because they want to gain valence electrons
Reactivity in nonmetals increases as you...
Move left and down the periodic table
Move right and down the periodic table
Move right and up the periodic table
Move left and up the periodic table

What happens to electrons if an element is less electronegative?
Lose electrons
gain electrons
have an increased reactivity
