Investigation #3 Flashcard: Coulomb's Law, Electrons, Properties

Front

What type of element is Silicon?

Back

Silicon is a metalloid, which means it has properties of both metals and nonmetals.

Front

What is Argon (Ar)?

Back

Argon is a noble gas, which is a group of elements that are colorless, odorless, and inert.

Front

If the attraction between two particles is 10, what could be the attraction if they are moved further apart?

Back

The attraction could be 5, as distance decreases the force of attraction.

Front

What type of element is dull, brittle, and does not conduct electricity?

Back

This element is a nonmetal.

Front

How many valence electrons do elements in the halogen family have?

Back

Elements in the halogen family have 7 valence electrons.

Front

What is Coulomb's Law?

Back

Coulomb's Law describes the force between two charged objects, stating that the force is directly proportional to the product of the charges and inversely proportional to the square of the distance between them.

Front

What is a semiconductor?

Back

A semiconductor is a material that has electrical conductivity between that of a conductor and an insulator, often used in electronic devices.

Front

What are the properties of metals?

Back

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

Front

What are the properties of nonmetals?

Back

Nonmetals are usually dull, brittle, and poor conductors of heat and electricity.

Front

What is the significance of valence electrons?

Back

Valence electrons determine how an element reacts chemically and its bonding behavior.
