How do the inner electron shells of an atom differ from the outer electron shells?
The electrons in the outer shells orbit the nucleus at slower speeds.
The electrons in the outer shells have negative charges; the electrons in the inner shells have positive charges.
Electrons in the inner shells are gained and lost more frequently than electrons in the outer shells.
The outer shells can hold more electrons than the inner shells.
An atom with one electron in its valence shell will tend to:
Become positively charged
Become negatively charged
Accept electrons from other atoms
Accepts protons from other atoms
Cations tend to have:
high valence
neutral valence
positive valence
negative valence
Fluorine is an element located on the right side of the periodic table of elements. What can you conclude about fluorine from this fact?
Its valence shell is nearly full.
It tends to donate electrons to other atoms.
It tends to form cations.
It tends to have a positive valence.
What can you infer about elements located in the middle of the periodic table?
They tend to have very large atomic masses.
They tend to have completely full valence shells.
They tend to have positive charges.
They tend to form ions less frequently than elements on the edges of the table.
Which of the following is a TRUE statement about ions?
Removing an electron from an atom requires energy.
When an atom gains an electron, it loses energy.
No energy is transferred when an atom gains or loses an electron.
Gaining and losing protons requires less energy than gaining and losing electrons.
Which statement BEST describes why sodium and chlorine form bonds so frequently?
A closed system can neither gain nor lose energy.
Opposites attract.
Objects in motion tend to remain in motion.
What goes up must come down.
Water is sometimes described as the "universal solvent." From the information presented in the BrainPOP Ions video, what can you infer about this nickname?
It means that water can make dangerous substances harmless.
It means that water dissolves electrons.
It means that water usually has a neutral charge.
It means that water can break the bonds that hold many substances together.
How is table salt (sodium chloride) different than the ions that make it up?
It has a net negative charge.
It has a net positive charge.
It has a neutral charge.
It contains no electrons.
Which of the following is a TRUE statement about atomic nuclei?
They are made up of protons, neutrons, and electrons.
They have a net positive charge.
Every atomic nucleus has the same number of particles.
The atomic nucleus has no relation to an atom's mass.
