What are materials called in which the electrons are loosely bound?
Materials in which the electrons are loosely bound are called conductors.
What is the internal structure of an atom?
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
Why do you use iodine solution during the preparation of slide of onion peel?
So that you can observe different characteristics of the cell clearer such as the nucleus, vacuoles or other membrane bound organelles.
How many electrons are in orbitals related to the 3rd energy level of a sulfur atom?
The sulfur atom has 16 electrons around its orbitals. The third energy level is the most tightly bound to the nucleus.
What material does not allow electrons to flow through it?
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.
What is an electron that is loosely bound to its nucleus called?
A valance electron.
What are materials called in which the electrons are loosely bound?
Materials in which the electrons are loosely bound are called conductors.
What are organisms that do not have a membrane bound nucleus called?
Organisms that do not have membrane-bound organelles, including a nucleus, are called Prokaryotic.
Does prokaryotic hold DNA?
Prokaryotes do have DNA, it just is not contained within a nucleus. It is loosely bound within the prokaryote.
Which atom requires the least energy for the removal of the most loosely bound electron a.Sn b.Sr c.Be d.Br?
C. Be. Beryllium.
What is an escaped electron called?
An escaped electron is called a FREE electron, simple as that. It means: not bound or belonging to a particular atom (or ion)
What is a cell called has a membrane bound nucleus and organelles?
eukaryote
Do the electrons of an atom have huge amounts of nuclear energy?
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.
Where is the DNA stored in a cell?
In the Membrane bound nucleus
Why is Cs more electropositive than Rb?
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
What is the outer shell of an atom?
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.
What are organisms whose cells lack membrane bound nucleus called?
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.
