Periodic Table Concepts and Trends

Mr. Folly's podcast covers periodic table trends, focusing on electronegativity, atomic and ionic radii, valence electrons, and reactivity. Fluorine and francium are highlighted as key examples of non-metal and metal reactivity, respectively. The podcast explains how atomic size and proton count affect attraction and reactivity, using relatable analogies to enhance understanding.

Which of the following is NOT a trend discussed in the introduction of the periodic table?

• Electronegativity

• Ionic radius

• Molecular weight

• Reactivity

What happens to the attraction between atoms as their size increases?

• Attraction remains the same

• Attraction decreases

• Attraction increases

• Attraction becomes unpredictable

Which element is the largest in terms of atomic size?

• Fluorine

• Oxygen

• Helium

• Francium

What is the relationship between protons and atomic attraction?

• More protons mean more attraction

• Protons decrease attraction

• Protons do not affect attraction

• More protons mean less attraction

Why is fluorine considered the most electronegative element?

• It has the most protons in its row

• It is the largest element

• It has the fewest protons in its row

• It is located at the bottom of the periodic table

How does the size of a cation compare to its neutral atom?

• Cations have unpredictable size

• Cations are the same size

• Cations are smaller

• Cations are larger

What is the number of valence electrons in argon?

• 2

• 8

• 4

• 6

What happens to anions in terms of size when they gain electrons?

• Their size becomes unpredictable

• They become smaller

• They become larger

• They remain the same size

Which element is considered the best metal reactor?

• Helium

• Fluorine

• Francium

• Oxygen

Why do noble gases not react?

• They are too large

• They have incomplete valence shells

• They are too small

• They have full valence shells
