Front

What is the electron cloud?

Back

The region around the nucleus of an atom where electrons are likely to be found.

Front

What is a metalloid?

Back

Elements that have properties of both metals and nonmetals; for example, Germanium.

Front

How do ionic bonds form?

Back

Ionic bonds form by the transfer of electrons from one atom to another.

Front

What is an electron?

Back

A negatively charged subatomic particle found in the electron cloud of an atom.

Front

What is a covalent compound?

Back

A chemical compound formed by the sharing of electrons between atoms, such as NO₂.

Front

What is the nucleus of an atom?

Back

The central part of an atom that contains protons and neutrons.

Front

What is the difference between ionic and covalent bonds?

Back

Ionic bonds involve the transfer of electrons, while covalent bonds involve the sharing of electrons.

Front

What are the properties of metalloids?

Back

Metalloids have intermediate properties between metals and nonmetals, such as conductivity and malleability.

Front

What is the significance of the electron cloud model?

Back

It provides a more accurate representation of the location and behavior of electrons in an atom.
