Question

13 multiple choice 1 point why does nickel (ni) have more coulombic attraction than platinum (pt)? nickels s valence electrons are on the same energy level as platinum s causing their valence electrons to be about the same distance from the nucleus. however, nickel has more protons in the nucleus to attract the valence electrons more. nickel has less energy levels causing the valence electrons to be closer to the protons in the nucleus. platinum has less energy levels causing the valence electrons to be closer to the protons in the nucleus. platinum s valence electrons are on the same energy level as nickel s causing their valence electrons to be about the same distance from the nucleus. however, platinum has more protons in the nucleus to attract the valence electrons more.

Explanation:

Step1: Understand Coulombic attraction

Coulombic attraction is between protons in nucleus and valence - electrons. Closer electrons experience more attraction.

Step2: Analyze energy levels

Nickel has fewer electron - energy levels than platinum. Fewer levels mean valence electrons are closer to the nucleus.

Step3: Evaluate options

The first option is wrong as nickel has fewer protons. The third option is wrong as it attributes the higher attraction to platinum which is incorrect. The correct reason is that nickel has less energy levels, making its valence electrons closer to the nucleus, resulting in more Coulombic attraction.

Answer:

Nickel has less energy levels causing the valence electrons to be closer to the protons in the nucleus.
