Front

What is an atom?

Back

An atom is the smallest unit of matter that retains the properties of an element.

Front

What is the difference between ionic and covalent bonds?

Back

Ionic bonds involve the transfer of electrons from one atom to another, while covalent bonds involve the sharing of electrons between atoms.

Front

What is the periodic table?

Back

The periodic table is a tabular arrangement of elements, organized by increasing atomic number, that shows the relationships between different elements.

Front

What is a molecule?

Back

A molecule is a group of two or more atoms bonded together, representing the smallest fundamental unit of a chemical compound.

Front

What is the significance of valence electrons?

Back

Valence electrons determine how an atom can bond with other atoms and are crucial in chemical reactions.
