Element Families, Valence Electrons & Ion Charge Flashcard

Front

What are element families?

Back

Element families, also known as groups, are columns in the periodic table that contain elements with similar chemical properties due to their similar valence electron configurations.

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

How many valence electrons do elements in Group 1 have?

Back

Elements in Group 1 have 1 valence electron.

Front

What is the ion charge of Group 1 elements when they form ions?

Back

Group 1 elements typically form ions with a +1 charge.

Front

What is the ion charge of Group 2 elements when they form ions?

Back

Group 2 elements typically form ions with a +2 charge.

Front

How many valence electrons do elements in Group 17 have?

Back

Elements in Group 17 have 7 valence electrons.

Front

What is the ion charge of Group 17 elements when they form ions?

Back

Group 17 elements typically form ions with a -1 charge.

Front

What is a metalloid?

Back

Metalloids are elements that have properties of both metals and nonmetals, and they are found along the zig-zag line on the periodic table.

Front

What are the properties of metals?

Back

Metals are typically malleable, ductile, good conductors of heat and electricity, and have a shiny appearance.

Front

What are the properties of nonmetals?

Back

Nonmetals are usually brittle, poor conductors of heat and electricity, and can be gases, liquids, or solids at room temperature.
