Neither... it knows stealing is wrong.
It is already stable.
10

two non-metals
metal with a non-metal
lanthanides with actinides
12
What is the name of the group of elements labeled #6?
lanthanides
actinides
halogens
noble gases
13

14
What determines how atoms bond?
the arrangement of electrons
all choices
the number of valence electrons
the number of electrons
15

salt-producing
can be hammered into thin sheets
can be made into wires
chemically non-reactive
16
What do you look at on the Periodic Table to find the number of valence electrons?

19
Is Sodium more or less likely to take another atom's electrons? Why?
less; it has 1 valence electron
more; it has 1 valence electron
20
What are the two ways atoms can bond?
sharing electrons and working together to steal electrons
hanging out and talking on the phone
gaining and losing electrons
sharing electrons and gaining/losing electrons
21
What goes in the middle of the electron dot notation?

Element's Symbol
22
What is the name of the group of elements labeled #7?
noble gases
actinides
halogens
lanthanides
23
What is this called?

A really confusing clock
24
What is the name of the group of elements labeled #5?
lanthanides
actinides
halogens
noble gases
25
Why do atoms bond?
to make all elements identical
to create nonmetals
to make stronger compounds
to achieve stability by filling outer electron shell
26
What is the octet rule?
all atoms want to have only 8 total electrons
all atoms want their outer shell filled with electrons (usually 8)
atoms want to have a minimum of 8 valence electrons
atoms with more than 8 electrons are stronger than other atoms
27
What two elements are exceptions to the octet rule?
Lithium and Beryllium
Hydrogen and Helium
Hydrogen and Lithium
Helium and Lithium
28

Neither... it knows stealing is wrong.
It is already stable.
less
more
29

What is electronegativity?
a measure of how well an unbonded atom attracts and holds electrons
a scale showing an atom's ability to attract and hold electrons
a measure of how many electrons an atom has
a comparison between the valence electrons in two atoms
