ISOTOPE NOTATION

Front

What is isotope notation?

Back

Isotope notation is a way to represent isotopes of an element, typically written as 'A/Z Element', where A is the mass number (protons + neutrons) and Z is the atomic number (number of protons).

What does the top number in isotope notation represent?

Back

The top number in isotope notation represents the mass number of the isotope.

Front

What does the bottom number in isotope notation represent?

Back

The bottom number in isotope notation represents the atomic number of the element.

Front

How do you determine the number of neutrons in an isotope?

Back

To find the number of neutrons, subtract the atomic number (number of protons) from the mass number.

Front

What is the mass number of an isotope with 15 protons and 15 neutrons?

Back

The mass number is 30 (15 protons + 15 neutrons).

Front

How many protons does the isotope P-30 have?

Back

P-30 has 15 protons.

Front

How many neutrons does the isotope Fe-56 have?

Back

Fe-56 has 30 neutrons (56 mass number - 26 protons).

Front

What is the charge of an ion with 8 protons and 10 electrons?

Back

The ion has a charge of -2 (8 protons - 10 electrons = -2).

Front

If an isotope has 37 protons and 48 neutrons, what is its mass number?

Back

The mass number is 85 (37 protons + 48 neutrons).

Front

What is the difference between atomic mass and mass number?

Back

Atomic mass is the weighted average mass of an element's isotopes, while mass number is the total number of protons and neutrons in a specific isotope.
