Element Lewis Dot and Ion Formation

Front

What are Lewis Dot Structures?

Back

Lewis Dot Structures are diagrams that represent the valence electrons of an atom as dots around the element's symbol, helping to visualize bonding and lone pairs.

Front

How many valence electrons does an atom with 5 valence electrons have?

Back

5 valence electrons.

Front

What ion will an atom with 5 valence electrons typically form?

Back

3- (it gains 3 electrons to achieve a full outer shell).

Front

What ion will potassium (K) form?

Back

1+ (it loses 1 electron to achieve a full outer shell).

Front

What is the charge of an ion formed by an atom with 7 valence electrons?

Back

Typically, it will form a 1- ion (it gains 1 electron to achieve a full outer shell).

Front

What is the maximum number of valence electrons an atom can have?

Back

8 valence electrons (octet rule).

Front

What is the octet rule?

Back

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

Front

How do you determine the number of energy levels in an atom?

Back

The number of energy levels corresponds to the period (row) of the periodic table the element is in.

Front

What is 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 difference between cations and anions?

Back

Cations are positively charged ions (lost electrons), while anions are negatively charged ions (gained electrons).
