Unit 5 Review

Front

How many electrons can f subshell hold?

Back

14

Front

What is the charge of a Carbon ion with 4 valence electrons?

Back

-4

Front

Bromine (Group 17) has 7 valence electrons. What would happen to Bromine?

Back

Bromine would gain 1 electron.

Front

How many more electrons does Nitrogen need to be like its Noble Gas neighbor (Neon #10)?

Back

3

Front

How many electrons would Oxygen (O) gain to have a full valence shell?

Back

2

Front

What is the maximum number of electrons in a subshell?

Back

The maximum number of electrons in a subshell is determined by the formula 2n², where n is the principal quantum number.

Front

What are valence electrons?

Back

Valence electrons are the electrons in the outermost shell of an atom that are involved in chemical bonding.

Front

What is the significance of the octet rule?

Back

The octet rule states that atoms tend to gain, lose, or share electrons to achieve a full outer shell of 8 electrons, leading to greater stability.

Front

What is a Lewis dot diagram?

Back

A Lewis dot diagram is a representation of an atom's valence electrons using dots around the element's symbol.

Front

What happens to an atom when it gains electrons?

Back

When an atom gains electrons, it becomes negatively charged and is called an anion.
