Coulombic Attraction

Front

What is Coulombic Attraction?

Back

Coulombic Attraction is the force of attraction between positively charged protons and negatively charged electrons in an atom.

Front

Which element has a smaller atomic radius: potassium (K) or bromine (Br)?

Back

Bromine (Br) has a smaller atomic radius than potassium (K).

Front

What is the relationship between Coulombic attraction and atomic radius?

Back

As Coulombic attraction increases, the atomic radius decreases.

Front

What happens to the force of attraction if the number of protons increases while the distance remains the same?

Back

The force of attraction increases.

Front

Which element has the strongest Coulombic attraction: O, F, N, or C?

Back

Fluorine (F) has the strongest Coulombic attraction.

Front

What is the role of distance in Coulombic attraction?

Back

The force of attraction decreases as the distance between charged particles increases.

Front

How does the charge of an ion affect its Coulombic attraction?

Back

Higher charges result in stronger Coulombic attraction.

Front

What is the formula for calculating Coulomb's Law?

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 the significance of Coulombic attraction in chemical bonding?

Back

Coulombic attraction is fundamental in forming ionic and covalent bonds between atoms.

Front

How does the number of electrons affect the atomic radius?

Back

More electrons can lead to increased electron-electron repulsion, which can increase the atomic radius.
