Periodic Table: Properties and Trends

Front

What are metals?

Back

Elements that are typically solid, shiny, malleable, and good conductors of heat and electricity; includes most elements.

Front

What is the name of family I in the periodic table?

Back

Alkali Metals.

Front

Why does Francium (Fr) have the lowest ionization energy in Group 1?

Back

Its 1 valence electron is very far from the nucleus, so little energy is needed to remove it.

Front

What is electronegativity?

Back

An atom's tendency to attract electrons to itself when it is chemically combined with another element.

Front

Which of the following is an Alkali Metal? Sodium, Magnesium, or Chromium?

Back

Sodium.

Front

What are nonmetals?

Back

Elements that are typically not shiny, are poor conductors of heat and electricity, and can be gases or brittle solids.

Front

What are metalloids?

Back

Elements that have properties of both metals and nonmetals.

Front

What is the periodic trend for atomic radius?

Back

Atomic radius generally increases down a group and decreases across a period.

Front

What is ionization energy?

Back

The energy required to remove an electron from an atom.

Front

What is the trend for ionization energy across a period?

Back

Ionization energy generally increases across a period from left to right.
