5. What is an atom?
the smallest component or part of an element having the chemical and physical properties of that element

6. What is the center of the atom called?
The core of every atom is called the nucleus.

7. What are the two parts of the nucleus?
Protons: Positively charged particles found inside of the atom’s nucleus.
Neutrons: Carry no charge; Found in the nucleus.

9. Negatively charged particles. Usually the same number as protons.
What is an electron?
Outside of the nucleus
Negatively charged particles.
Usually the same number as protons.

11. The parts of an atom
The protons, neutrons, and electrons are called subatomic particles,
Subatomic means smaller parts that make up an atom.

They are so small.
(snap, snap)
They’re round like ball.
They make up the air.
They’re everywhere.

22. Who are the residents of Matterville?

23. How do you find the following information about an element?
Number of protons
Equal to the atomic number

24. How do you find the following information about an element?
Number of electrons
Equal to the atomic number

25. Why are protons and electrons the same number?
All things in nature must balance.
There must be positive and negative charges to equal zero.
If there are more protons are added, then that is no longer the same element.

26. Why are protons and electrons the same number?
If there are protons taken away, it is not the same element.
All elements have an exact number of protons. That is how they are arranged by atomic number.

27. How do you find the number of neutrons?
