2
Fluorine (F) is an element located on the right side of the periodic table. That means F is...
It tends to donate electrons to other atoms
Its valence shell is nearly full
It tends to form cations
It tends to have a positive valence
3

In outer space
Deep within the Earth
In the Earth's atmosphere
In a science lab
4
Which of the following is a true statement about ions?
No NRG is transferred when atoms gain or lose electrons
When an atom gains an electron, it loses NRG
It requires less NRG to gain or lose electrons than protons
Removing an electron from an atom requires NRG
5
Which statement best describes why sodium and chlorine form bonds so frequently?
Opposites attract
Objects in motion tend to remain in motion
What goes up must come down
A closed system can neither gain nor lose energy
6
An atom with one electron in its valenceshell will tend to:
Become positively charged
They tend to have completely full valence shells
Become negatively charged
Accept protons from other atoms
7
Noble gases are sometimes called "inertgases. What does the word "inert" mean in chemistry?
Refers to substances that do not react with other substances

It refers to gases
It refers to substances that easily lose electrons
8
How do the inner electron shells of an atom differ from the outer electron shell?
Electrons in the inner shells have positive charges
Electrons in the outer shells orbit nucleus at slower speeds
