Chemistry Chapter 1: Chemical Bonds and Compounds

Which term describes the attraction between atoms that holds them together in a compound?

What do you call a molecule that has both a slight positive and a slight negative end due to unequal sharing of electrons?

What defines a compound in chemistry?

Which type of bond forms when two atoms share one or more pairs of valence electrons?

Which of the following describes an ion?

Lesson 1

A chemical bond is a force that holds atoms together.
A compound is a material made of two or more different kinds of atoms joined by chemical bonds.
An electron dot diagram, also known as a Lewis dot diagram, shows valence electrons as dots around an element's chemical symbol.
Valence electrons are the outermost electrons in an atom; they participate in chemical bonding.

Lesson 2

A chemical bond—in a compound—is a force that holds atoms together.
A chemical formula uses symbols to represent elements and numbers to show how many atoms of each element make up a compound.
A covalent bond occurs when atoms share one or more pairs of valence electrons.
A molecule is a group of atoms held together by covalent bonds.
A polar molecule has a slightly positive end and a slightly negative end due to unequal sharing of electrons.

Lesson 3

An ion is an atom that has a charge because it has lost or gained valence electrons.
An ionic bond forms due to the attraction between positively and negatively charged ions.
A metallic bond forms when many metal atoms share their pooled valence electrons.

This quiz covers the fundamental concepts of chemical bonds and compounds. It explores topics such as electron dot diagrams, covalent and ionic bonds, and the structure of molecules. Test your understanding of how atoms interact and form different substances.
