Practice Test Part 2

Front

Which element has a larger atomic radius: Iron or Titanium?

Back

Titanium has a larger atomic radius than Iron.

Front

Which element loses 1 electron to attain an octet?

Back

Potassium (group 1) loses 1 electron to attain an octet.

Front

What is the electron arrangement of Fe³⁺ ions?

Back

The electron arrangement of Fe³⁺ ions is 1s² 2s² 2p⁶ 3s² 3p⁶ 3d⁵.

Front

Ionic compounds are formed between which types of elements?

Back

Ionic compounds are formed between metals and nonmetals.

Front

Which element has a larger atomic radius: Sodium or Aluminum?

Back

Sodium has a larger atomic radius than Aluminum.

Front

Define atomic radius.

Back

Atomic radius is the distance from the nucleus of an atom to the outermost shell of electrons.

Front

What is the octet rule?

Back

The octet rule states that atoms tend to gain, lose, or share electrons to achieve a full outer shell of eight electrons.

Front

What is the significance of electron configuration?

Back

Electron configuration describes the distribution of electrons in an atom's orbitals, which determines its chemical properties.

Front

What are ionic bonds?

Back

Ionic bonds are formed through the transfer of electrons from one atom to another, resulting in the attraction between positively and negatively charged ions.

Front

What is the difference between metals and nonmetals in terms of electron behavior?

Back

Metals tend to lose electrons and form cations, while nonmetals tend to gain electrons and form anions.
