Starter: Atomic Structure/Average Atomic Mass

Front

What is a neutral atom?

Back

A neutral atom is an atom where the number of protons equals the number of electrons, resulting in no overall charge.

Front

What are isotopes?

Back

Isotopes are atoms of the same element that have the same number of protons but different numbers of neutrons, leading to different atomic masses.

Front

How can you determine if two atoms belong to the same element?

Back

Two atoms belong to the same element if they have the same number of protons.

Front

What is average atomic mass?

Back

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

Front

Where is the mass of an atom located?

Back

The mass of an atom is primarily located in the nucleus.

Front

What makes up the volume of an atom?

Back

The volume of an atom is made up of the electron cloud surrounding the nucleus.

Front

What is the charge of a proton?

Back

A proton has a positive charge.

Front

What is the charge of a neutron?

Back

A neutron has no charge (it is neutral).

Front

What is the charge of an electron?

Back

An electron has a negative charge.

Front

How do you calculate the average atomic mass of an element with two isotopes?

Back

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