Answer 1

The exercise is to connect terms like 'diatomic molecule' and 'halogen' to their correct definitions, such as 'formed of two atoms' and 'a family of very reactive elements that gain or share one electron', respectively.

Step-by-step explanation:

The task is to match each term with its definition in the context of chemistry, specifically relating to the periodic table and elements:

• a. Diatomic molecule - (c) Formed of two atoms. Diatomic molecules include hydrogen (H2), nitrogen (N2), oxygen (O2), fluorine (F2), and chlorine (Cl2).
• b. Halogen - (f) A family of very reactive elements whose atoms gain or share one electron. Examples include fluorine and chlorine.
• c. Metalloid - (a) A type of element that has some of the characteristics of metals and some of nonmetals. Silicon and germanium are metalloids with important semiconductor properties.
• d. Inert gases - (b) A family of unreactive elements whose atoms do not gain, lose, or share valence electrons. Noble gases like helium and neon are inert gases.
• e. Nonmetal - (e) A type of element whose physical properties are generally opposite to that of metals, like carbon or sulfur.
• f. Semiconductor - (d) A substance that carries electricity under certain circumstances, but not under others. Silicon and germanium are common semiconductors used in electronic devices.
