The traditional explanation for this is that the electrostatic attraction of the electrons to the nucleus of an atom is reduced by repulsion of the other electrons present in an atom without positive charge. If an isoelectronic ion has a positive charge, the effect of repulsions is reduced because of the smaller number of electrons, and the resulting stronger attraction to the positively charged nucleus pulls the outer electrons closer. However, all such questions about the properties of atoms should preferably be answered in a purely mathematical manner by quantum mechanics.

When electrons feel an increasing positive charge do they have a higher or lower energy?
When electrons feel an increasing positive charge, they have a higher energy. This occurs because the attraction between the negative charge of the electron and the positive charge causes the electron to move to a higher energy state.
What element has an ion that is smaller than an ion of calcium?
Fluorine has an ion, specifically the fluoride ion (F⁻), that is smaller than a calcium ion (Ca²⁺). The fluoride ion has a negative charge, which increases its electron cloud size, but its atomic radius is still smaller than that of the calcium ion, which has lost two electrons and has a higher positive charge. Consequently, the increased nuclear charge in Ca²⁺ pulls the remaining electrons closer, resulting in a smaller ionic radius compared to that of F⁻.
How does the size of a magnesium ion with a 2 positive charge compare with that of a sodium ion with a single positive charge?
The magnesium ion (Mg2+) is smaller than the sodium ion (Na+) because as atoms lose electrons and become positively charged ions, they lose electron shells, making them smaller. The higher charge of the magnesium ion also pulls the electrons closer to the nucleus, further reducing its size compared to the sodium ion.
Cations are formed when neutral atoms lose?
Cations are formed when neutral atoms lose electrons, leading to a positive charge. This loss of electrons results in a higher number of protons compared to electrons in the atom, creating an overall positive charge.
Why do smaller highly charged ions have a greater affinity for an ion exchange column than larger ions with a smaller charge?
Smaller highly charged ions can penetrate deeper into the matrix of an ion exchange column due to their size, interacting more closely with the functional groups on the resin. This results in stronger electrostatic interactions and a higher affinity for the column compared to larger ions with a smaller charge.
When electrons feel an increasing positive charge do they have a higher or lower energy?
When electrons feel an increasing positive charge, they have a higher energy. This occurs because the attraction between the negative charge of the electron and the positive charge causes the electron to move to a higher energy state.
How strong is the charge of a proton?
Proton is the positive charge of an atom. So obviously it has a higher charge that electron (negative) and neutron (neutral).
What is the difference between neutrons and protons?
protons have a positive charge and neutrons have no charge...
What atom is smaller tin or germanium?
Germanium atoms are smaller than tin atoms because germanium has a higher atomic number and more protons in the nucleus. The increased positive charge from more protons attracts the negatively charged electrons more strongly, leading to a smaller atomic size.
What element has an ion that is smaller than an ion of calcium?
Fluorine has an ion, specifically the fluoride ion (F⁻), that is smaller than a calcium ion (Ca²⁺). The fluoride ion has a negative charge, which increases its electron cloud size, but its atomic radius is still smaller than that of the calcium ion, which has lost two electrons and has a higher positive charge. Consequently, the increased nuclear charge in Ca²⁺ pulls the remaining electrons closer, resulting in a smaller ionic radius compared to that of F⁻.
What is the definition for positive charge?
having a deficiency of electrons ;having a higher electric potential
Are negative numbers higher than normal numbers?
What do you mean by "higher?"They are smaller than positive numbers since they are to the left of positive numbers on the number line.Beyond that, not sure what you mean.

The magnesium ion (Mg2+) is smaller than the sodium ion (Na+) because as atoms lose electrons and become positively charged ions, they lose electron shells, making them smaller. The higher charge of the magnesium ion also pulls the electrons closer to the nucleus, further reducing its size compared to the sodium ion.
What is the relationship between electronegativity and core charge?
Electronegativity is a measure of an atom's ability to attract electrons in a chemical bond, while core charge refers to the positive charge in the nucleus of an atom taking into account the shielding effect of inner electrons. Generally, atoms with higher core charge tend to have higher electronegativity as they have a stronger pull on electrons due to their increased positive charge in the nucleus.
What is the significance of effective nuclear charge in chemistry and how does it impact the behavior of atoms and molecules?
The effective nuclear charge in chemistry refers to the net positive charge experienced by an electron in an atom, which affects its attraction to the nucleus. It impacts the behavior of atoms and molecules by influencing their size, ionization energy, and reactivity. A higher effective nuclear charge leads to stronger attraction between the electrons and the nucleus, resulting in smaller atomic size, higher ionization energy, and lower reactivity.
Does the carbon atom have the delta negative charge in the carbon-chlorine bond?
No, as t is less electronegative it has a partial positive charge.
Why proton is positively charged?
I am going to borrow heavily from the answer to "Why do electrons have a negative charge?" Protons have a positive charge because the charge is part of what the particle is made of. If it were possible to remove the positive charge from the proton we would then have a neutron.
