What else can I help you with?
What are free electrons of conductor?
First we have to define the word an electron, An electron is negatively charged particle. A metal is a substance consists of number of both electrons and protons. Electrons emitted from the metal surface through different ways such ways as Thermionic, Photoelectric, etc. Free electrons of conductor are electrons emitted from conductor when it disturbed through ways as mentioned above
Define energy level shell?
Energy level shell is a region around an atom's nucleus where electrons are likely to be found. Electrons in an atom occupy these shells, each with a specific energy level. The shells are designated by numbers (n=1, 2, 3, etc.) and can hold a certain maximum number of electrons based on their energy level.
Which subatomic particle determines reactivity?
Electrons are the subatomic particles that determine the reactivity of an element. The number of electrons in the outermost shell of an atom, known as valence electrons, determines how likely an atom is to form chemical bonds with other atoms.
What are the electrons in the outer shell?
The electrons in the outermost shell of an atom are called valence electrons. These electrons are involved in forming chemical bonds with other atoms to create molecules. The number of valence electrons influences the reactivity and chemical properties of an element.
The electrons that occupy the outermost filled shell are called?
Outer energy level electrons, or valence electron.
What did Niels Bohr define the organization of?
the atomic electrons.
Define what an insulator is?
They don't let neutrons or electrons through.
What is the term current mean?
it define electrons flow measured in ampere.
What is the electron configuration when you have 0 electrons?
When ionised to have no electrons, the usual notation would be 1s0. However, this is almost never needed, as other information and context will usually imply or define that there are no electrons.
How would you define ionic and covalent?
Ionic bond-bond formed by donating or transfer of electrons. Covalent bond-bond formed by sharing of electrons.
Do atoms have different amounts of protons neutrons and electrons?
An atom is comprised of a nucleus of protons and neutrons, and layers of 'shells' in which the electrons revolve around the nucleus. An element is defined by the number of protons in the nucleus while the number of electrons on the outer shell define an atoms group on the periodic table. Then the number of neutrons is added to the number of protons to define the atomic weight of the atom.
Define Conventional current?
Current as a transfer of (+) charge so thats its direction of flow is opposite to that of electrons which are (-) charged
How are electrons less than all atoms?
They have less mass; and depending on how you define their "size", they also have less size.
Define atomic radii?
The atomic radii is the measure of the size of the atoms in a chemical element. This is the distance from the nucleus to the boundary of the electrons' cloud.
Define Internal Resistance?
The internal resistance of a device is the resistance in ohms of that device. It is the resistance electrons need to overcome before electricity is said to flow.
What type chemical bond must be present for most chemist to define molecules?
"covalent" OR "covalent bond"
