Unit 06 Review - Bonding - 1 Ionic - 531

Front

What causes atoms to bond?

Back

Attraction of nuclei to the valence electrons of the other atom.

Front

How many valence electrons does aluminum (Al) have?

Back

3

Front

What is a noble gas configuration?

Back

A stable electron arrangement similar to that of noble gases, typically having 8 valence electrons.

Front

What type of ion does iodine (I) most likely form?

Back

1- anion.

Front

What is the proper electron-dot diagram for a phosphorus anion?

Back

Phosphorus anion (P^3-) has 8 valence electrons represented as: :P: (with 3 additional electrons).

Front

Define ionic bonding.

Back

Ionic bonding is the electrostatic attraction between oppositely charged ions.

Front

What is a cation?

Back

A cation is a positively charged ion formed by the loss of electrons.

Front

What is an anion?

Back

An anion is a negatively charged ion formed by the gain of electrons.

Front

How do you determine the charge of an ion formed by a main group element?

Back

The charge is determined by the number of valence electrons: elements tend to lose or gain electrons to achieve a full outer shell.

Front

What is the octet rule?

Back

The octet rule states that atoms tend to gain, lose, or share electrons to have eight valence electrons.
