What is an Ionic Bond?

Back

An Ionic Bond is a type of chemical bond that occurs when one atom transfers electrons to another atom, resulting in the formation of charged ions that attract each other.

Front

What is a Covalent Bond?

Back

A Covalent Bond is a type of chemical bond where two atoms share one or more pairs of electrons.

Front

What is a pure substance?

Back

A pure substance is a material that has a constant composition and consistent properties throughout, such as elements and compounds.

Front

What is a mixture?

Back

A mixture is a combination of two or more substances that retain their individual properties and can be separated by physical means.

Where are Transition Metals located on the Periodic Table?

Back

Transition Metals are found in groups 3 to 12 of the Periodic Table, typically in the center.

Front

What is the Bohr model of an atom?

Back

The Bohr model is a representation of an atom where electrons orbit the nucleus in defined paths or energy levels.

Front

What are Chemical Properties?

Back

Chemical Properties are characteristics of a substance that describe its ability to undergo chemical changes, such as reactivity and flammability.

Front

What are Physical Properties?

Back

Physical Properties are characteristics that can be observed or measured without changing the substance's chemical identity, such as color, melting point, and density.

Front

What is the atomic number?

Back

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

Front

What is the difference between an element and a compound?

Back

An element is a pure substance made of only one type of atom, while a compound is made of two or more different types of atoms chemically bonded together.
