Protons and electrons have opposite charges. Neutrons, as the name implies, are neutral.
Electron capture is the absorption of an electron by an atomic nucleus if that nucleus is neutron poor. An electron is captured, usually from an inner electron shell of that atom, and it will convert a proton in the nucleus into a neutron. We know that a neutron is converted into a proton and an electron in neutron decay, so it might be looked at as something of an opposite nuclear reaction where a proton and an electron combine to form a neutron.

an electron is much lighter than a proton or neutron.
Yes, an example of an electrostatic force acting in an atom is a proton attracting an electron. This attraction occurs due to the opposite charges of the proton (positive) and the electron (negative), leading to the electrostatic force of attraction between them.

A neutron has no charge. That's why it is called a neutron; the neu part stands for neutral, meaning without charge. The charge of an electron, which is -1, is equal and opposite to the charge of a proton, which is +1.
If a proton would be 1, an electron would be 0.000544. An electron is 1,836 times lighter than a proton. A neutron would be 1.001 as a proton is 99.86% the mass of a neutron

The electron is the smallest having about 1/1836th the mass of a proton or neutron, which means that basically an electron has no mass. The neutron and proton weigh the same both having a mass of 1.
The three principal particles of an atom are the proton, electron and neutron. The proton and electron have +1 and -1 charges respectively. The neutron does not have a charge.
