Synthesis Session on Atomic Structure

Synthesis Session on Atomic Structure

LEARNING TARGETS 

• I can identify the subatomic particles in an atom and their respective charges and role in an atom.

• I can clearly define the concepts of atomic number and mass number, and how they relate to isotopes.

• I can relate the atomic number and mass number of an atom with the numbers of each subatomic particle present in an atom.

Synthesis Questions

Open Ended

1. What is an ATOMIC NUMBER?

1. What is an ATOMIC NUMBER?

• refers to the number of protons

• serves as the identity of an atom

• number of protons = number of electrons (neutral atom)

Open Ended

2. What is ATOMIC MASS?

2. What is ATOMIC MASS?

•  TOTAL number of protons and neutrons

• All atomic nuclei contain BOTH protons and neutrons (except Hydrogen which has 1 proton but no neutron)

4. What is an ION?

4. What is an ION?

 a charged atom 

(During a chemical reaction, the number of protons remains the same in the atomic nucleus, but the electrons may be lost by an atom and gained by another)
