List the following in order of increasing force of attraction
1. an electron in the outer shell of carbon atom (in the ground state level) 1.1*10^(-10)m a part from nucleus.
2.an electron in the outer shell of oxegen atom (in the ground state level) 9.0*10^(-11)m a part from nucleus.
3.an electron in the outer shell of sulfur atom (in the ground state level) 1.5*10^(-10)m a part from nucleus
I would look at the ionization potential for each of the elements. The largest ionization potential is the one with the greatest attraction.
no thing given rather then this information and this is exam question how i can look for ionization energy?
You can google "table ionization potentials".
To determine the force of attraction between an electron and the nucleus of an atom, you can use the concept of atomic radius. In general, the closer an electron is to the nucleus, the greater the force of attraction.
Given the distances of the electrons from the nucleus, we can compare the forces of attraction in order of increasing magnitude:
2. Electron in the outer shell of oxygen atom: 9.0*10^(-11)m from the nucleus.
3. Electron in the outer shell of sulfur atom: 1.5*10^(-10)m from the nucleus.
1. Electron in the outer shell of carbon atom: 1.1*10^(-10)m from the nucleus.
Therefore, the order of increasing force of attraction would be:
2 < 3 < 1
