question 1 (1 point)
which of the following terms represents the smallest part of an element that still has the properties of that element?

o a
o b
o c
o d
cell
atom
molecule
water

Explanation:

• A cell is the basic unit of life in biology, not related to elements.
• An atom is the smallest unit of an element that retains the chemical properties of that element.
• A molecule is made up of atoms (e.g., \(O_2\) is a molecule of oxygen element made of two oxygen atoms). But a single atom of an element (like a single \(O\) atom for oxygen - in some cases, noble gases exist as single - atom elements) is the smallest for the element.
• Water (\(H_2O\)) is a compound, not an element.

Answer:

B. atom
