<h2>Atoms whose atomic number are the same but whose mass numbers are different are called : Isotopes </h2>
Explanation:
Isotopes
They are the elements with same atomic number but different mass number .
for example : Protium , deuterium and tritium are isotopes of hydrogen .
: C-14 and C-12 are isotopes of oxygen .
: Cl-35.5 and Cl-37 are isotopes of chlorine
Alpha particles
They are helium nuclei with +2 unit charge and 4 a.m.u mass
They are represented as : He₂⁴.
Ions
The atom carrying charge is called as ion .
It can be of two types : Cation and anion
cation :atom with positive charge
Anion : atom with negative charge
Beta particles
They are actually particles with charge and mass of electron and is represented as :₀ e⁻¹
IBM and others are using copper instead of aluminum in the most powerful computer chips they manufacture. Because of copper's superior electrical conductivity, this technology enables conductor channel lengths and widths to be significantly reduced.
We call it a solid because it has the () and in s inside of it meaning solid
Answer:
A process that involves rearrangement of the molecular or ionic structure of a substance, as opposed to a change in physical form or a nuclear reaction.
Explanation:
Pretty much just not a physical reaction or otherwise
Answer:
(1) cathode: Y
(2) anode X
(3) electrons in the wire flow toward: Y
(4) electrons in the wire flow away from: X
(5) anions from the salt bridge flow toward X
(6) cations from the salt bridge flow toward Y
(7) gains mass: Y
(8) looses mass X
Explanation:
The voltaic cell uses two different metal electrodes, each in an electrolyte solution. The anode will undergo oxidation and the cathode will undergo reduction. The metal of the anode will oxidize, going from an oxidation state of 0 (in the solid form) to a positive oxidation state, and it will become an ion. At the cathode, the metal ion in the solution will accept one or more electrons from the cathode, and the ion’s oxidation state will reduce to 0. This forms a solid metal that deposits on the cathode. The two electrodes must be electrically connected to each other, allowing for a flow of electrons that leave the metal of the anode and flow through this connection to the ions at the surface of the cathode. This flow of electrons is an electrical current that can be used to do work, such as turn a motor or power a light.
