IS3 - Coulomb's Law & Forces in the Atom

Front

What do metals tend to do in terms of electron behavior?

Back

Metals tend to lose electrons and become cations.

Front

What happens to the force between two charged objects if you triple the magnitude of one charge?

Back

The force becomes 3X (3 times stronger).

Front

What happens to the force between two charged objects if you reduce the distance between them from 30 cm to 10 cm?

Back

The force becomes 9X (9 times stronger).

Front

When distance increases, what happens to electrostatic force?

Back

The electrostatic force decreases; this represents an inverse relationship.

Front

What do nonmetals tend to do in terms of electron behavior?

Back

Nonmetals tend to gain electrons and become anions.

Front

Define Coulomb's Law.

Back

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

Front

What is the formula for calculating the electrostatic force between two charges?

Back

F = k * (|q1 * q2|) / r^2, where F is the force, k is Coulomb's constant, q1 and q2 are the charges, and r is the distance between the charges.

Front

What is an ion?

Back

An ion is an atom or molecule that has a net electrical charge due to the loss or gain of one or more electrons.

Front

What is the difference between cations and anions?

Back

Cations are positively charged ions (formed by losing electrons), while anions are negatively charged ions (formed by gaining electrons).

Front

How does increasing the distance between two charged objects affect the force?

Back

Increasing the distance decreases the electrostatic force between the objects.
