Question

the chart lists four different kinds of atoms.
different kinds of atoms
calcium
gold
argon
iodine
what is true about all of these atoms?
they cannot be solids.
they are the largest units of matter
they are the only types of atoms that exist
they cannot be divided and still keep the properties of the element

Explanation:

1. Analyze the first option: Gold is a solid, so "They cannot be solids" is false.
2. Analyze the second option: Atoms are not the largest units of matter (molecules, etc., can be larger), so this is false.
3. Analyze the third option: There are many more types of atoms (elements) than just these four, so this is false.
4. Analyze the fourth option: By definition, an atom is the smallest unit of an element that retains the element's properties and cannot be divided (in a chemical sense) and still keep the element's properties. This matches the definition of an atom.

Answer:

The correct statement is: They cannot be divided and still keep the properties of the element.
