Whats the difference between Nuclear and Hyphen Form?
100
Does hyphen notation use the symbol of an element?
No, the full name of the element is used, not the symbol.
100
What is an isotope?
An isotope is an element that has 2 or more different atoms with the same number of protons but different numbers of neutrons.
100
The mass number of an atom is equal to the # of ___ + # of ___?
Protons + Neutrons
200
In nuclear notation, where does the mass number go?
In the upper left corner of the element symbol.
200
True or False:
Hyphen notation includes the atomic number of an element.
False.
Hyphen notation only includes the mass number of an element.

How would you write the most common isotope of hydrogen in hyphen notation?
Hydrogen-1.
400
Does the atomic number change in isotopes?
No, the atomic number does not change because isotopes of the same element have the same number of protons.

How would you write the element Cu in hyphen notation?
Copper-64.
500
When are isotopes the most stable?
When the number of protons and neutrons in the nucleus is the same. And the mass corresponds to the mass on the PT
