Isotopic Notation

Front

What is isotopic notation?

Back

Isotopic notation is a way of representing isotopes of an element, typically written as 'Element Symbol - Mass Number' (e.g., Li-6).

Front

How many neutrons does the isotope of lithium (Li-7) have?

Back

Li-7 has 4 neutrons.

Front

Isotopes occur when atoms of the same element have a different number of ___________.

Back

neutrons.

Front

Different isotopes have __________.

Back

different masses.

Front

What is the proper equation for determining the number of neutrons for a given isotope?

Back

mass # - atomic #.

Front

Which atom has 4 neutrons?

Back

Li-7.

Front

What is the mass number of an isotope?

Back

The mass number is the total number of protons and neutrons in the nucleus of an atom.

Front

What is the atomic number of an element?

Back

The atomic number is the number of protons in the nucleus of an atom, which defines the element.

Front

How do isotopes of the same element differ?

Back

Isotopes of the same element differ in the number of neutrons and therefore have different mass numbers.

Front

What is an example of an isotope?

Back

Carbon-12 (C-12) and Carbon-14 (C-14) are examples of isotopes of carbon.
