Atomic structure review

Front

What are isotopes?

Back

Isotopes are atoms of the same element that have the same number of protons but different numbers of neutrons.

Front

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

Back

The number of neutrons can be found by subtracting the atomic number (number of protons) from the mass number.

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 an electron configuration?

Back

An electron configuration is the distribution of electrons in an atom's orbitals.

Front

What does an excited state of an atom mean?

Back

An excited state occurs when an electron absorbs energy and moves to a higher energy level.

Front

What is the mass number of an atom?

Back

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

Front

What is the wave-mechanical model of the atom?

Back

The wave-mechanical model describes electrons as wave functions and defines orbitals as regions of space where electrons are likely to be found.

Front

What is the significance of the periodic table in atomic structure?

Back

The periodic table organizes elements based on their atomic number and electron configurations, helping to predict chemical behavior.

Front

What is the relationship between protons and electrons in a neutral atom?

Back

In a neutral atom, the number of protons equals the number of electrons.

Front

What is an orbital?

Back

An orbital is a region in an atom where there is a high probability of finding an electron.
