Chemistry Chapter 5 Quiz

The total number of protons and neutrons in an atom's nucleus.

Electrons fill orbitals in a way that minimizes energy, with each orbital getting one electron before doubling up.

A shorthand way to represent the electron configuration of an element by using the previous noble gas configuration.

Atoms with the same number of protons but a different number of neutrons.

The ability of a material to transfer heat.

The number of protons in an atom's nucleus, which determines the element's identity.

The arrangement of elements in the periodic table based on their atomic number and recurring chemical properties.

The regions around the nucleus of an atom where electrons are most likely to be found. They have specific shapes and energy levels.

Electrons located in the outermost shell of an atom, which are involved in chemical bonding. They determine an element's reactivity.

A rule stating that atoms tend to gain, lose, or share electrons to achieve a stable configuration with eight valence electrons, like the noble gases.
