Question

molecules

1. one or more atoms that are bonded together are called a
2. molecules are the smallest part of a compound that keep the

of the compound
examples:

Explanation:

Question 7:

In chemistry (a subfield of Natural Science), when one or more atoms are bonded together, they form a molecule. So the term for bonded atoms is a "molecule".

Question 8:

Molecules are the smallest part of a compound that retain the chemical properties of the compound. So the blank should be filled with "chemical properties".

Examples:

Common examples of molecules include \( \ce{H_2O} \) (water, made of 2 hydrogen and 1 oxygen atom), \( \ce{O_2} \) (oxygen, diatomic molecule), \( \ce{CO_2} \) (carbon dioxide, 1 carbon and 2 oxygen atoms), \( \ce{CH_4} \) (methane, 1 carbon and 4 hydrogen atoms).

Answer:

1. molecule
2. chemical properties

Examples: \( \ce{H_2O} \) (water), \( \ce{O_2} \) (oxygen), \( \ce{CO_2} \) (carbon dioxide), \( \ce{CH_4} \) (methane) (any valid molecular compounds or diatomic molecules can be listed)
