# Best answer: Does the number of protons affect the force of attraction?

Contents

## Do more protons mean more attraction?

The more protons, the greater the attraction for an atom’s electrons. The more electrons, the less the attraction for an atom’s electrons.

## What happens to the force of attraction as the number of protons increase?

As more protons are added, the attractive force on the electron increases. 10. What would be the attractive force on a single electron if five protons were in the nucleus of an atom?

## What is the relationship between the number of protons and the force of attraction?

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 factors can affect the force of attraction in an atom?

In an atom, the most important factors that influence the force, as calculated by Coulomb’s equation, are the nuclear charge and the distance from the nucleus to the electron of interest. The closer an electron is to a nucleus, the stronger the attractive force (i.e. the more negative F becomes).

## What factors affects electrostatic attraction?

As we’ll discuss in this lesson, he found that the force between charged particles was dependent on only two factors: the distance between the particles and the amount of electric charge that they carried.

## Does more protons mean more energy?

The more protons in the nucleus, the stronger the attraction of the nucleus to electrons. This stronger attraction makes it more difficult to remove electrons. Within a group, the ionization energy decreases as the size of the atom gets larger.

## How does increasing the number of protons change how strongly the nuclei of atoms are attracted to valence electrons of the same energy level?

Ionization energy INCREASES as you go ACROSS a period because the number of protons increase, so there is a greater attraction to the nucleus. The strong attraction to the nucleus requires more energy for the valence e- to be removed. … The atomic number increases, so the amount of protons in the nucleus increases.

## What factors influence the strength of 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.

## What is the force of attraction of one proton?

Hence, the electrostatic force of attraction between a proton and an electron in a hydrogen atom is \$9.216 times {10^{ – 8}}{text{ N}}\$ . Note: Although the magnitude of the charge on an electron and a proton is the same but their signs are opposite of each other.

## Can the differences in attractive forces be explained by a change in the number of protons in the nucleus?

Yes; The more protons in the nucleus, the stronger the attraction force. For each set of elements below, circle the element whose atoms will have a stronger attractive force between their outermost electron(s) and the nucleus.

## What happens to the number of protons in the nucleus as you go across a period?

Across a period, electrons are being added to the same energy level, but the number of protons in the nucleus increases. This attracts the energy level closer to the nucleus and the atomic radius decreases across a period.
