Intro to Bonding Flashcard 2023

Front

What is an ionic compound?

Back

An ionic compound is formed when a metal transfers electrons to a nonmetal, resulting in the formation of cations and anions that are held together by electrostatic forces.

Front

What is the electronegativity difference for a nonpolar covalent bond?

Back

The difference in electronegativity between two atoms must be less than 0.4 for the bond to be considered nonpolar covalent.

Front

What is a cation?

Back

A cation is a positively charged ion that is formed when an atom loses one or more electrons.

Front

How are electrons shared in a nonpolar covalent bond?

Back

In a nonpolar covalent bond, electrons are shared evenly between the two atoms.

Front

How are ionic bonds formed?

Back

Ionic bonds are formed by a transfer of electrons from a metal to a nonmetal.

Front

What is the characteristic of ionic compounds regarding melting points?

Back

Ionic compounds typically have high melting points due to the strong electrostatic forces between the ions.

Front

Do ionic compounds conduct electricity in water?

Back

Yes, ionic compounds conduct electricity in water when they dissociate into their constituent ions.

Front

What is the difference between polar and nonpolar covalent bonds?

Back

Polar covalent bonds involve unequal sharing of electrons, while nonpolar covalent bonds involve equal sharing.

Front

What is electronegativity?

Back

Electronegativity is a measure of an atom's ability to attract and hold onto electrons in a chemical bond.

Front

What happens to the charge of an atom when it gains electrons?

Back

When an atom gains electrons, it becomes negatively charged and is called an anion.
