Answer :
In atom has 11 protons, 12 neutrons, and 10 electrons. this atom has an atomic number of 11 , an atomic mass of 23 , and an overall charge of +1 .
What is electron?
Unattached or attached to an atom, an electron is a negatively charged subatomic particle (not bound). One of the three main types of particles inside an atom, along with protons and neutrons, is an electron that is linked to the atom.
An atom's nucleus is made up of electrons, protons, and neutrons. The positive charge of a proton balances out the negative charge of an electron. An atom is in a neutral state if its protons and electrons are equal in number.
They have a mass that is considerably lower, exist outside of the nucleus, and display both wave- and particle-like properties. Since an electron is also a fundamental particle, it is unreinforced and unbroken.
