2. the nucleus of an atom is located ______.

Explanation:

Question 1

To determine the correct definition of an atom, we analyze each option:

• Option a: An atom is indeed the smallest part of an element that retains the element's properties. This aligns with scientific definitions.
• Option b: A molecule is made of atoms (or same/different elements), so an atom is not a type of molecule. Eliminate.
• Option c: Atoms are extremely small, far too small to be seen with the naked eye. Eliminate.
• Option d: Cells are biological structures, atoms are sub - atomic particles. Eliminate.

The three main parts of an atom are protons, neutrons, and electrons. Protons and neutrons are located in the nucleus, and electrons orbit the nucleus.

The nucleus of an atom is located at the center of the atom. Electrons are found in electron clouds (orbitals) surrounding the nucleus.

Answer:

a) The smallest part of an element that retains the properties of that element.
