Atomic Structure Flashcard

Front

What is the average atomic mass of an element?

Back

The average atomic mass is the weighted average of the masses of an element's isotopes, taking into account their relative abundance.

Front

How do you calculate the average atomic mass of an atom with multiple isotopes?

Back

Multiply the mass of each isotope by its relative abundance (as a decimal), then sum these values.

Front

What are the three main subatomic particles?

Back

Protons, Neutrons, and Electrons.

Front

What is the charge of a proton?

Back

A proton has a positive charge.

Front

What is the charge of an electron?

Back

An electron has a negative charge.

Front

What is the charge of a neutron?

Back

A neutron is electrically neutral (no charge).

Front

Where are protons located in an atom?

Back

Protons are located in the nucleus of an atom.

Front

Where are neutrons located in an atom?

Back

Neutrons are also located in the nucleus of an atom.

Front

Where are electrons located in an atom?

Back

Electrons are located in the electron cloud surrounding the nucleus.

Front

What is the mass of a proton compared to a neutron?

Back

A proton and a neutron have approximately the same mass, about 1 amu.
