Matter Matters
What is matter?
Anything that has mass and takes up space.
What charge does a proton have?
Positive (+)
What charge does a neutron have?
No charge / neutral, 0 charge
What charge does an electron have?
Negative (-)
What does an element's atomic number tell you?
The number of protons in an atom of that element.
Name two examples of matter.
Answers may include water, air, a desk, a pencil, or a rock.
Where is a proton located in an atom?
In the nucleus.
Where are neutrons found?
In the nucleus.
Where are electrons found?
In the electron cloud/energy levels surrounding the nucleus.
What element has atomic number 6?
Carbon (C)
What are the three common states of matter?
Solid, liquid, and gas.
What does the number of protons identify?
The element.
What two particles are found in the nucleus?
Protons and neutrons.
Which particle has the smallest mass: proton, neutron, or electron?
Electron
What element has atomic number 17?
Chlorine (Cl)
How does heating a substance affect particle movement?
Particles move faster when thermal energy is added.
An atom has 8 protons. What element is it?
Oxygen.
An atom has 6 protons and 8 neutrons. What is its mass number?
14
An atom has 10 protons and 10 electrons. Is it neutral or charged?
Neutral, because the positive and negative charges are the same
An element has 13 protons, 14 neutrons, and 10 electrons. Identify the element, mass number, and charge.
Aluminum (Al), mass number 27, charge +3.
How does particle arrangement differ between a solid and a gas?
Solid particles are tightly packed and vibrate in place; gas particles are far apart and move freely.
An atom has 12 protons. If it gains another proton, what happens to its identity?
It becomes a different element because the number of protons determines the element.
An atom has 17 protons and 18 neutrons. What is its mass number?
35
An atom has 11 protons and 10 electrons. Is it neutral, positive, or negative? What is its charge?
It is an ion with a +1 charge because it has one more proton than electron.
Who is the greatest science teacher of all time?
Mr. Ward, duh?
