2024 Unit 2A Periodic Trends and Intro to Bonding Test Review

Front

What happens to bond energy when the bond is stronger?

Back

The bond energy is larger.

Front

What occurs to the size of an atom when it gains an electron to form an anion (-)?

Back

The size will increase.

Front

What is the condition for covalent bonds to form in chemical compounds?

Back

Pairs of electrons are shared between two nonmetal atoms.

Front

What do electrons do in a metallic bond?

Back

They float around freely.

Front

Which compound has the strongest chemical bonds based on a potential energy diagram?

Back

Y2.

Front

Define bond energy.

Back

Bond energy is the amount of energy required to break one mole of a bond in a gaseous substance.

Front

What is an anion?

Back

An anion is a negatively charged ion formed when an atom gains one or more electrons.

Front

Explain the concept of electronegativity.

Back

Electronegativity is the ability of an atom to attract electrons in a chemical bond.

Front

What is the difference between ionic and covalent bonds?

Back

Ionic bonds involve the transfer of electrons, while covalent bonds involve the sharing of electrons.

Front

What is a metallic bond?

Back

A metallic bond is a type of chemical bond that occurs between metal atoms, characterized by a 'sea of electrons' that are free to move.
