They aren't held IN atoms. They are held AROUND atoms. Yet, the answer you seek is still simple. The Protons of any given atom contain a positive charge value of +1. Each Electron carries a negative charge of -1. These opposites attract, and that's why the Electrons stay in place.
Bound electrons are the electrons locked in orbit of the atom which are held in orbit by its attraction to the positive charge of the proton(s) in the nucleus. Electrons have a negative charge. Conversely, the free electrons are electrons that are not orbiting the nucleus of an atom normally in the form of static electricity. Valence electrons are the electrons orbiting the outermost shell of the atom are weakly held by the positive proton charges and can be transferred to or shared with one or more other atoms. Valence electrons are bound until they are freed by some outside force or reaction.
Ionic bonding occurs when one atom donates electrons to another atom, resulting in the formation of positively and negatively charged ions that are held together by electrostatic forces. This bond is typically formed between a metal cation and a nonmetal anion.
The electrons in the valence band, this can be 1 to 8 electrons (in the s and p orbitals of the outer shell) depending on the element.
Electrons shared in a molecule are held closer to the atom with the larger nucleus due to its greater positive charge, which exerts a stronger attractive force on the negatively charged electrons. This results in the electron density being unequally distributed in the molecule, creating a partial negative charge near the atom with the larger nucleus.
The interference of inner electrons in an atom can shield the attraction of outer electrons to the nucleus. This is because the inner electrons create a repulsive force that counteracts the attractive force between the outer electrons and the nucleus. As a result, the outer electrons may not be held as tightly to the nucleus, leading to weaker bonding and reactivity in the atom.
electrostatic force between the nucleus and the electrons.
Electrons are held within the atom by the attraction between their negative charge and the positive charge of the nucleus. This attraction, known as the electromagnetic force, keeps the electrons in orbit around the nucleus in specific energy levels.
Yes.

Ionic molecules donate electrons.
the electrons on the last shell of an atom are called valency electrons.

Electrons are held in place by the electromagnetic force exerted between them and the positively charged protons in an atom's nucleus. This force keeps electrons in orbit around the nucleus, preventing them from flying off into space.
Valence electrons are the electrons least tightly held by the atom and by definition are the electrons in the outermost shell of the electron and are highest in energy. They are the electrons that often contribute to an elements reactivity and in the case of Sodium, which as one valence electron in its ground state, it "gives up" its electron when it comes in contact with water.
