Ions EXAM HR

Front

What do atoms become when they lose electrons?

Back

Cations are positively charged ions formed when atoms lose electrons.

Front

What do atoms become when they gain electrons?

Back

Anions are negatively charged ions formed when atoms gain electrons.

Front

What do the yellow circles represent in a metal structure?

Back

The yellow circles represent electrons, which are negatively charged particles surrounding the nucleus.

Front

What solution was NOT tested during the ions lab?

Back

Coconut Water was not tested during the ions lab.

Front

How many valence electrons does calcium have?

Back

Calcium has 2 valence electrons.

Front

Define an ion.

Back

An ion is an atom or molecule that has a net electrical charge due to the loss or gain of one or more electrons.

Front

What is the charge of a cation?

Back

A cation has a positive charge.

Front

What is the charge of an anion?

Back

An anion has a negative charge.

Front

What role do valence electrons play in ion formation?

Back

Valence electrons are involved in the formation of ions; atoms lose or gain these electrons to achieve a stable electron configuration.

Front

What is the octet rule?

Back

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