Atoms and Isotopes
If the atomic number is carbon is 6 and the mass number is 12 and the number of neutrons is 6 then what is the hyphen notation of carbon?
12
How many neutrons, protons, and electrons are in carbon if the mass number is 12?
6
Where is the electron located?
Around the nucleus
What is an Isotope?
Atoms of the same element with different mass numbers
Where is the protons and neutrons located?
Inside the Nucleus
Why can't you change the number of protons?
It will change the substance
Nuclear Force (aka "strong force")
Keeps the nucleus from breaking apart About 100's stronger than electromagnetic force
What charge does electrons have?
Negative charge
What charge does neutrons have?
Neutral charge
What's equal in an Atom?
Nucleus and Electrons
Atomic number
Number of protons
What does the mass in an element equal to?
Number of protons and neutrons
Electromagnetic Force
Opposites attract Keeps the electrons near nucleus
What charge does protons have?
Positive charge
What's equal in a Neutral Atom?
Protons and Electrons
What's equal in a nucleus?
Protons and Neutrons
What makes up the mass number?
Protons and Neutrons because they have nearly all of the mass together?
What does the Atomic number equal?
The number of electrons in a neutral atom because positive protons equals negative electrons
What does the valance electrons tells you on the shell?
The number of electrons on the third ring
What does the periods (row) tells you?
The number of shells (energy levels)
What does the group number (1-8) tells you?
The number of valance electrons (electrons on the outside shell)
