1
Which particle of an element is the smallest and still has properties of that element?
Proton
Atom
Neutron
Electron
2
Where are electrons located in an atom?
The electron cloud
Next to neutrons in the nucleus
Next to protons in the nucleus
Electrons are not found in an atom
3
What part of the atomic model contains almost all of the mass?
The neutron
The nucleus
The electron cloud
The proton
4
Why do we use models to represent atoms?
It demonstrates the artistic abilities of scientists
It shows the reactivity of an atom
It demonstrates how atoms form
It demonstrates the basic structure of an atom
5
How can the motion of particles in a solid best be described?
the particles are close, but able to slide past each other
the particles are able to move rapidly in all directions
the particles are far apart
the particles are close together and vibrate in place
6
Which subatomic particle can be found inside the nucleus of an atom?
protons and neutrons
electrons and protons
neutrons only
electrons and neutrons
7
The modern atomic theory has been modified since Dalton's original theory. Why has it changed?
New evidence was discovered to support the modifications
Changes were based on opinions/beliefs of modern scientists
The public no longer believed the original theory
Theories should be replaced every 100 years
8
What causes scientific theories to change over time?
the Nobel Peace prize
theories cannot change over time
a single experiment
new evidence from multiple sources
9

Which statement is true about atoms?
Atoms can be separated into elements
Atoms are founds only in living things
All elements are made up of several types of atoms
An atom is the smallest unit of an element
11
What is common among all three states of matter (solids, liquids, gases)?
There is no particle motion
All particles are tightly packed together
They all take the shape of their containers
Particles are constantly moving
12
Oxygen has an atomic number of 8. What does that atomic number tell you about oxygen?
The average atomic mass of oxygen
The amount of kinetic energy in the atom of oxygen
The state of matter at room temperature
The number of protons in the oxygen atom
13
How do the particles in a solid compare to the particles in a liquid?
The particles in a solid have more energy than in a liquid
The particles in the liquid can slide past one another
The particles in the liquid have less energy than the solid
The particles that make up the solid are far apart
14
How do you determine the number of neutrons in the atom of an element?
Subtract atomic number from the mass number
Subtract the number of protons from the atomic number
Subtract the number of electrons from the number of protons
Subtract the number of electrons from the atomic number
15
In the image of the atom, what do the black spheres represent?
Protons
Electrons
Nucleus
Neutrons
