an electron loosely bound to its nucleus is called a free electron.
It means that it can easily escape.

Materials in which the electrons are loosely bound are called conductors.
The atom is a basic unit of matter that consists of a dense central nucleus surrounded by a cloud of negatively charged electrons. The atomic nucleus contains a mix of positively charged protons and electrically neutral neutrons. The electrons of an atom are bound to the nucleus by the electromagnetic force
So that you can observe different characteristics of the cell clearer such as the nucleus, vacuoles or other membrane bound organelles.
The sulfur atom has 16 electrons around its orbitals. The third energy level is the most tightly bound to the nucleus.
An insulator or a dielectric is the generic name for a material which does not allow electrons to flow through it. Many polymers such as PE, PP, PVC etc are insulators. Ceramics such as hardened clay are also insulators. Others include:glassrubberbakeliteoilsphosphorussulfurwoolsilicone rubberssilicone oilsteflonnylonpolycarbonateacrylicabsetc.Such materials are insulators. Insulators are materials that don't have free electrons available for the flow of electrons, which is called an electric current.Insulators are either pure elements which have a "full" outer electron shell (containing 8 electrons, which makes a full set for the shell) or they are compounds that have their electrons completely bound, with none available to flow away in a current.Further notes:All insulators can have their outer shell electrons broken loose if a high enough voltage is applied. This is called the dielectric breakdown voltage."Conductors" are elements that have only 1 or 2 electrons in the outer shell. These elements' electrons are loosely bound to their atoms and are already moving around in the crystalline structure. The application of a voltage to a conductor will cause these electrons to flow from negative to positive. This flow is what is called the current.
A valance electron.
Materials in which the electrons are loosely bound are called conductors.
Organisms that do not have membrane-bound organelles, including a nucleus, are called Prokaryotic.
Prokaryotes do have DNA, it just is not contained within a nucleus. It is loosely bound within the prokaryote.

An escaped electron is called a FREE electron, simple as that. It means: not bound or belonging to a particular atom (or ion)
eukaryote
No, the electrons do not have nuclear energy, they are not part of the nucleus. They have binding energy which keeps them attached to the nucleus as part of the atom. When an electron is bound to an atom, it has a potential energy that is inversely proportional to its distance from the nucleus. This is measured by the amount of energy needed to unbind the electron from the atom, and is usually given in units of electronvolts (eV). In the quantum mechanical model, a bound electron can only occupy a set of states centered on the nucleus, and each state corresponds to a specific energy level. The lowest energy state of a bound electron is called the ground state, while an electron at a higher energy level is in an excited state. The binding energy of electrons is many orders of magnitude less than the binding energies in the nucleus, and atoms are easily ionised by stripping off electrons.
In the Membrane bound nucleus
The single outer electron is further away from the nucleus and thus is less tightly bound and thus it is energetically easier to remove that electron
The outer shell is the valence electrons and they are very loosely bound to the nucleus - less force by the nucleus on the valence electrons, so valence shell's electrons are exchanged first in any reaction.
A prokaryote is a single-celled organism that lacks a membrane-bound nucleus (karyon), mitochondria, or any other membrane-bound organellesIt is the Eukarotes that have membrane-bound organelles.
