Identifying Protons and Neutrons in Isotopes

These flashcards cover the concepts related to calculating the number of protons and neutrons in isotopes, particularly focusing on nickel.

Mass Number

The total number of protons and neutrons in an atom.

Atomic Number

The number of protons in an atom, which is unique to each element.

Isotope

Atoms of the same element that have different numbers of neutrons.

Nickel (Ni)

An element with atomic number 28.

Calculation of Neutrons

Subtract the atomic number from the mass number to find the number of neutrons.

Protons in Nickel Isotope

An atom of the Nickel isotope contains 28 protons.

Neutrons in Nickel Isotope

An atom of the Nickel isotope contains 32 neutrons.

Difference between Mass Number and Atomic Mass

Mass number is used in calculations regarding protons and neutrons, while atomic mass is found on the periodic table and can differ due to isotopes.

Nuclear Notation

A representation of an isotope that shows the mass number and atomic number.

Importance of Periodic Table

Helps in locating the atomic number of elements.
