SPS1a Atom Models Practice

Front

What is atomic mass?

Back

Atomic mass is the weighted average mass of an element's isotopes, measured in atomic mass units (amu). It is typically found on the periodic table.

Front

How do you find the number of protons in an element?

Back

The number of protons in an element is equal to its atomic number, which can be found on the periodic table.

Front

What is the maximum number of electrons that can occupy the second energy level?

Back

The second energy level can hold a maximum of 8 electrons.

Front

What is the maximum number of electrons that can occupy the third energy level?

Back

The third energy level can also hold a maximum of 8 electrons.

Front

What is the Bohr model of the atom?

Back

The Bohr model is a representation of the atom where electrons orbit the nucleus in defined paths or energy levels.

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 determines the element's identity.

Front

What is the significance of the periodic table?

Back

The periodic table organizes elements based on their atomic number, electron configuration, and recurring chemical properties.

Front

What is an isotope?

Back

An isotope is a variant of a chemical element that has the same number of protons but a different number of neutrons.

Front

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

Back

To find the number of neutrons, subtract the atomic number from the atomic mass (rounded to the nearest whole number).

Front

What is the difference between atomic mass and atomic weight?

Back

Atomic mass is the mass of a single atom, while atomic weight is the average mass of an element's isotopes, taking into account their natural abundance.
