Which atom has the strongest attraction between the nucleus and its own electrons?
Fluorine has the greatest attraction for electrons in any bond that it forms.
Which element has the strongest coulombic attraction?
Magnesium ion has a higher coulombic attraction compared to the coulombic attraction of Sodium. This is why Magnesium ion is more reactive than Sodium Ion. (Sodium has a +1 charge and Magnesium has a +2 charge.
Does barium or calcium have a stronger attractive force?
Barium has more electrons shells than calcium, so the nuclear shielding is stronger, and the outmost electrons are further away from the nucleus. This results in a weaker attractive force between the electron and the nucleus, so a smaller energy is required to remove it.
What are the independent and dependent variables in the data coulombic attraction?
a. What are the independent and dependent variables in the data? Independent-number of protons. Dependent-attractive force.
Which 4 elements have the highest electronegativity and what does this mean about their attraction for bonded electrons?
Of the main group elements, fluorine has the highest electronegativity (EN = 4.0) and cesium the lowest (EN = 0.79). This indicates that fluorine has a high tendency to gain electrons from other elements with lower electronegativities.
Which atom has a stronger attraction between the nucleus and the outer valence electrons explain your reasoning lithium and oxygen?
Lithium has less protons but also has less electrons. The electrons of Li are also closer to the positive nucleus and have less shielding resulting in greater attraction. There are more electrons in Rb which result in very far away valence electrons.
How would you describe the coulombic attraction between the nucleus of the atom and the two electrons in the 4s sublevel?
How would you describe the Coulombic attraction between the nucleus of the atom and the two electrons in the 4s sublevel? The attractive force is equal for both electrons. … The attractive force between the valence electrons and the nucleus decreases.
What factors influence the strength of the attraction of each atom to its electrons?
An atom’s electronegativity is affected by both its atomic number and the size of the atom. The higher its electronegativity, the more an element attracts electrons. The opposite of electronegativity is electropositivity, which is a measure of an element’s ability to donate electrons.
Why is barium bigger than calcium?
The elements calcium and barium are both in the same Group 2 with calcium being higher, so for the neutral atoms, Ca would have a smaller radius, its outer electrons being in the n = 4 level as compared with the n = 6 level for the Ba atom.
Which factors determine the amount of attractive force between protons and electrons?
Coulombic: how does amount of protons influence attraction between protons and electrons? The greater the number of protons, the greater the pull on the electrons, which means greater force.
What would cause the attractive force between the nucleus and outer electrons to be increased?
increases; because the number of charges on the nucleus increases, that attracts the bonding pair of electrons more strongly. There is a special stability in ________ energy levels.
