Periodic Table Patterns

Front

How does the atomic radius change across a period and down a group?

Back

Across a period, the atomic radius decreases; down a group, it increases.

Front

How does electronegativity change across a period and down a group?

Back

It increases across a period and decreases down a group.

Front

How does metallic character change across a period and down a group?

Back

It decreases across a period and increases down a group.

Front

How do melting points differ between metals and nonmetals?

Back

Metals generally have higher melting points than nonmetals.

Front

Which two properties change in a similar way as you move from left to right across the periodic table’s periods and down its groups?

Back

Electronegativity and ionization energy

Front

Which noble gas has the largest atomic radius?

Back

Radon

Front

Which metal would you expect to have the greatest metallic character?

Back

Francium, as it is the most metallic element and its atoms tend to lose electrons easily.

Front

The melting point of sulfur (S) is expected to be:

Back

Lower than iron (Fe)

Front

What type of bond would you expect sulfur to form with each of these elements?

Back

Covalent bond
