Coulombic Attraction and Atomic Forces

Mr. Decker explains Coulombic attraction, where oppositely charged particles attract. The force of attraction is influenced by distance and the number of charges. As distance increases, the force decreases. More protons increase the force, but multiple electrons do not divide the force. In elements like sodium and chlorine, more protons result in stronger attraction, regardless of electron count.

What is the primary concept of Coulombic attraction?

• Like charges repel each other.

• Neutral particles attract charged particles.

• Charged particles do not interact.

• Oppositely charged particles attract each other.

What is the charge of a proton?

• Variable

• Neutral

• Positive

• Negative

How does the force of attraction change as the distance between a proton and an electron increases?

• The force becomes zero immediately.

• The force decreases.

• The force increases.

• The force remains constant.

In an atom, where are the protons located?

• In the electron shell

• In the outer ring

• In the nucleus

• In the electron cloud

What happens to the force of attraction when the number of protons is increased?

• The force decreases.

• The force becomes zero.

• The force remains the same.

• The force increases.

What happens to the force of attraction if an electron is on a larger ring?

• The force becomes zero.

• The force remains the same.

• The force increases.

• The force decreases.

What is the force of attraction when there is one proton and one electron?

• 6.9 Nano Newtons

• 4.6 Nano Newtons

• 2.3 Nano Newtons

• 1.1 Nano Newtons

If there are two protons and two electrons, how is the force of attraction distributed among the electrons?

• The electrons repel each other.

• The force is only on one electron.

• The force is divided equally between the electrons.

• Each electron experiences the full force of attraction.

Why does chlorine have a stronger force of attraction on its electrons compared to sodium?

• Chlorine has fewer electrons.

• Chlorine has more electron rings.

• Chlorine has more protons.

• Chlorine has fewer protons.

How does the number of protons affect the force of attraction in elements of similar size?

• More protons result in a weaker force.

• More protons result in a stronger force.

• The number of protons has no effect.

• The force is only affected by electrons.
