Protons, Neutrons, Electrons Review

Front

What are protons?

Back

Protons are positively charged subatomic particles found in the nucleus of an atom. They determine the atomic number and identity of an element.

Front

What are neutrons?

Back

Neutrons are neutral subatomic particles located in the nucleus of an atom. They contribute to the atomic mass and stability of the nucleus.

Front

What are electrons?

Back

Electrons are negatively charged subatomic particles that orbit the nucleus of an atom in various energy levels or shells.

Front

What is an ion?

Back

An ion is an atom or molecule that has gained or lost one or more electrons, resulting in a net electrical charge.

Front

What is a cation?

Back

A cation is a positively charged ion, formed when an atom loses one or more electrons.

Front

What is an anion?

Back

An anion is a negatively charged ion, formed when an atom gains one or more electrons.

Front

What are valence electrons?

Back

Valence electrons are the electrons in the outermost shell of an atom that are involved in chemical bonding.

Front

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

Back

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

Front

What is the significance of the atomic orbital diagram?

Back

The atomic orbital diagram visually represents the arrangement of electrons in an atom's orbitals, indicating their energy levels and sublevels.

Front

What is the electron configuration of oxygen?

Back

The electron configuration of oxygen is 1s² 2s² 2p⁴.
