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

Front

What type of bond is formed between two nonmetals?

Back

Covalent bond.

Front

What is electronegativity?

Back

The ability of an atom to attract electrons when in a compound.

Front

What is the bond type between selenium (Se) and chlorine (Cl)?

Back

Covalent bond.

Front

How does bond strength relate to bond energy?

Back

When the bond is stronger, the bond energy is larger.

Front

Why do ionic compounds not conduct electricity in solid state?

Back

Their ions are held in fixed positions, not free to move.

Front

What is an ionic bond?

Back

A bond formed through the transfer of electrons from one atom to another.

Front

What is the periodic law?

Back

The properties of elements are periodic functions of their atomic numbers.

Front

Define ionization energy.

Back

The energy required to remove an electron from an atom in its gaseous state.

Front

What is atomic radius?

Back

The distance from the nucleus of an atom to the outermost shell of electrons.

Front

How does atomic radius change across a period?

Back

It decreases from left to right across a period.
