Front

Who is known as the Father of the Periodic Table?

Back

Dimitri Mendeleev

Front

What are the electrons located furthest from the nucleus called?

Back

Valence Electrons

Front

What is the significance of valence electrons in chemical bonding?

Back

Valence electrons determine how an atom can bond with other atoms.

Front

How does the periodic table help predict the properties of elements?

Back

Elements in the same group have similar chemical properties due to their similar valence electron configurations.

Front

What is the relationship between atomic number and element identity?

Back

The atomic number uniquely identifies an element and corresponds to the number of protons in its nucleus.

Front

What is the general trend of atomic size across a period?

Back

Atomic size decreases from left to right across a period due to increasing nuclear charge.

Front

What is the general trend of electronegativity down a group?

Back

Electronegativity decreases down a group due to increased distance between the nucleus and valence electrons.
