Question

Which of the following options correctly describe the form(s) in which elements exist in nature? Select all that apply.

a) Diatomic molecules
b) Monoatomic ions
c) Polyatomic ions
d) Molecular compounds

Answer 1

Elements can exist in the forms of diatomic molecules and monoatomic ions in nature.

Step-by-step explanation:

In nature, elements can exist in different forms. The options that correctly describe the form(s) in which elements exist in nature are:

• Diatomic molecules: Some elements exist as diatomic molecules, meaning they are found in pairs in nature. Examples include hydrogen (H₂), oxygen (O₂), and nitrogen (N₂).
• Monoatomic ions: These are ions formed from only one atom. Examples include Cl-, Na+, Mg2+, and Ca2+.

Based on the given options, these are the correct choices. Molecular compounds can be formed when different elements combine, but they do not represent the form in which elements exist naturally.
