Physical Science quiz

Structure of an atom: Atoms

Smallest unit of mater that retains the properties of an element.

Subatomic Particles: Protons

Positively charged particles located in the nucleus

Subatomic Particles: Neutrons

Neutral particles found in the nucleus

Subatomic Particles: Electrons

Negatively charged particles located in the electron cloud surrounding the nucleus

Subatomic Particles: Nucleus

The dense central region of an atom containing protons and neutrons

Atomic number and mass: Atomic number

The number of protons in the nucleus of an atom; identifies the element

Atomic number and mass: Mass number

The total number of protons and neutrons in an atoms’ nucleus

Atomic number and mass: Isotopes

Atoms of the same element with different numbers of neutrons

Atomic number and mass: Atomic mass

The weighted average mass of all naturally occurring isotopes of an element

The periodic table: Periods

Horizontal rows on the periodic table; tells number of shells

The periodic table: Groups/families

Vertical columns; elements in the same group have similar chemical properties; tells number of valence electrons

The periodic table: Metals, Nonmetals and Metalloids

Metals are typically shiny, good conductors of heat and electricity and malleable.

The periodic table: Metals, Nonmetals and Metalloids

Nonmetals are poor conductors and often brittle.

The periodic table: Metals, Nonmetals and Metalloids

Metalloids have properties of both metals and nonmetals

Electron configuration: Energy levels

Electrons are organized into specific levels around the nucleus

Electron configuration: Valence electrons

Electrons in the outermost energy level; they determine chemical bonding

Electron configuration: Electron dot diagrams

Visual representation of an atoms’ valence electrons

The Role of Quarks: Quarks

Subatomic particles that make up protons and neutrons

The Role of Quarks: Quarks

Protons and neutrons consist of three quarks held together by strong forces

Electron Cloud

The area around the nucleus where electrons are likely to be found
