Ion Formation

Front

What are anions?

Back

Anions are negatively charged ions that are formed when atoms gain electrons.

Front

What is the Lewis dot structure for phosphorus?

Back

The Lewis dot structure for phosphorus has three single electrons and one pair of electrons.

Front

What is an exception to the octet rule?

Back

Helium is an exception to the octet rule as it is stable with only two electrons.

Front

What charge does calcium form when it becomes an ion?

Back

Calcium forms a +2 charge when it becomes an ion.

Front

Which element forms an ion with the same charge as the oxide ion?

Back

Sulfur forms an ion with the same charge as the oxide ion.

Front

What are cations?

Back

Cations are positively charged ions that are formed when atoms lose 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

How do you determine the charge of an ion from the periodic table?

Back

The charge of an ion can be determined by its group number in the periodic table; for example, group 2 elements typically form +2 ions.

Front

What is the significance of the Lewis dot structure?

Back

The Lewis dot structure represents the valence electrons of an atom and helps in understanding bonding and molecular structure.

Front

What is the charge of the oxide ion?

Back

The oxide ion has a charge of -2.
