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
Which subatomic particle determines reactivity?
Electrons, for chemical reactions
What state of matter has a define volume but no define shape?
plasma
What are the electrons in the outer shell?
Those electrons are the valence electrons. They are the electrons which mostly take part in exchange of electrons or sharing of electrons. Hence, valence shell electrons are a very important part of chemistry since all the reactions due to them only.
What is the scientific meaning of the word define?
the word define means explain what the object is for Example: if i were to define a wheel i would say it is round not square, it is rubber and it burns.
What did Niels Bohr define the organization of?
the atomic electrons.
Define what an insulator is?
They don't let neutrons or electrons through.
How does Lewis define acids and bases?
acid: accepts lone pair electrons bases:donates lone pair electrons
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.
How did Lewis define a base?
Lewis base is defined as a compound which can donate a lone pair 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.
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 Conventional current?
Current as a transfer of (+) charge so thats its direction of flow is opposite to that of electrons which are (-) charged
Define quantum yield of a photo chemical reaction?
In photochemical reaction we have photons that passed to the surface starting photochemical reaction - producing some electrons. quantum yield=produced electrons/passed photons.
Define the Term Element?
an element is made of protrons nutrons and electrons...
