Is a positive charge attracted to the electrons around atoms?

In summary, lone positive charges can bond covalently with other atoms due to the induction of a dipole. This is due to the fact that all bonds at the atomic and molecular level are caused by electromagnetism, with gravitational forces playing a minimal role and strong and weak forces mainly affecting processes on the nuclear level. Therefore, if something has an effect on you, is not radioactive, and is not affected by gravity, it is most likely due to electromagnetism.

An atom has an equal amount of positive and negative charges. But those charges are not all in exactly the same spot. Electrons are closer to other atoms than the protons are. So, would a lone positive charge be attracted towards the electrons in an atom?

Absolutely - a lone proton will induce a dipole in a neutral atom and can bond covalently. Compare the bond energies of adding a proton to a molecule,

to the energy of the same covalently bonded molecules,

they are of the same order or even higher. So an H+ ion will form a very strong bond with most molecules.
Cool, thanks for your reply. I took chemistry in high school but I never realized that covalent bonds were simply atoms being attracted to each other.

In fact, all bonds at atomic and molecular level are caused by electromagnetism. The scale is far too small for gravitational forces to play a role and the strong and weak forces mainly affect processes on the nuclear level.

A good rule of thumb is that if it has an effect on you, is not radioactive, and not gravity - then it is electromagnetism.

Yes, a positive charge is attracted to the electrons around atoms. This is because positive and negative charges have opposite charges and therefore, they attract each other. In an atom, the protons are located in the nucleus and the electrons orbit around the nucleus. The electrons are much smaller and lighter than the protons, so they are able to move closer to other atoms. This creates an imbalance in the distribution of charges, with more negative charges being closer to other atoms than positive charges. As a result, a lone positive charge would be drawn towards the electrons in an atom due to their strong attractive force. This is known as the electrostatic force and is a fundamental principle in understanding the behavior of charged particles in atoms and molecules.
 

Related to Is a positive charge attracted to the electrons around atoms?

1. How does a positive charge attract electrons around atoms?

A positive charge attracts electrons around atoms through the electrostatic force. This force is created by the difference in charge between the positive charge and the negatively charged electrons. The positive charge exerts a force on the electrons, pulling them towards the positively charged nucleus of the atom.

2. Why are electrons attracted to a positive charge?

Electrons are attracted to a positive charge because of the opposite charges they possess. According to Coulomb's law, opposite charges attract each other, so the negatively charged electrons are attracted to the positively charged nucleus of the atom.

3. Can a positive charge attract multiple electrons at once?

Yes, a positive charge can attract multiple electrons at once. This is because the electrostatic force between the positive charge and the electrons is a non-contact force, meaning it can act on multiple particles at the same time.

4. What happens when a positive charge comes into contact with a negatively charged atom?

When a positive charge comes into contact with a negatively charged atom, the electrostatic force between them causes the electrons to move towards the positively charged object. This creates a flow of electricity, known as an electric current.

5. Is a positive charge always attracted to electrons around atoms?

Not always. If there is an equal number of positive and negative charges, they will cancel each other out and there will be no attraction. Additionally, if the positive charge is strong enough, it can overcome the attraction of the electrons and repel them instead.
