6th_Unit 1 Review Flashcard

Front

What is a solid?

Back

A solid is a state of matter where particles are closely packed together in a rigid structure, maintaining a fixed shape and volume.

Front

What type of particles are found in the cloud surrounding an atom's nucleus?

Back

Negatively charged particles, known as electrons, are found in the cloud surrounding the nucleus of an atom.

Front

What is a pure substance?

Back

A pure substance is a material that has a constant composition and consistent properties throughout. Examples include elements and compounds.

Back

An atom consists of a nucleus containing positively charged protons and neutral neutrons, surrounded by negatively charged electrons in energy levels.

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.
