Atomic Structure, Periodic Table, Valence Electrons Flashcard

Front

What is the Modern Periodic Table of Elements arranged by?

Back

The Modern Periodic Table of Elements is arranged by atomic number.

Front

How many valence electrons does carbon have?

Back

Carbon has 4 valence electrons.

Front

What is the maximum number of electrons in the innermost energy level?

Back

The innermost energy level can hold a maximum of 2 electrons.

Front

How many valence electrons does Aluminum have?

Back

Aluminum has 3 valence electrons.

Front

What does the atomic mass tell you?

Back

The atomic mass tells you basically the number of protons and neutrons.

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 atomic number?

Back

The atomic number indicates the number of protons in an atom and determines the element's identity.

Front

How do you determine the number of neutrons in an atom?

Back

The number of neutrons can be determined by subtracting the atomic number from the atomic mass.

Front

What is the maximum number of electrons in the second energy level?

Back

The second energy level can hold a maximum of 8 electrons.

Front

What is the relationship between valence electrons and chemical reactivity?

Back

Elements with fewer valence electrons tend to be more reactive, as they seek to lose or gain electrons to achieve a full outer shell.
