An anode is an electrode, it can be a metal or another conductor. in an electrochemical cell that is polarized if an electric current flows into it. Electric current flows opposite to the direction of movement of electrons. In electrochemical processes, both galvanic cells (batteries) and electrolysis cells, anodes undergo oxidation.
In contrast to an Anode, a Cathode is an electrode pole in an electrochemical cell that is polarized if this pole is positively charged (so that an electric current will flow out of it, or the movement of electrons will enter this pole).
In galvanic cells or power plants (batteries), the anode is the negative pole. The electrode will release electrons towards the circuit and hence an electric current flows into this electrode and makes it an anode and negative.
Answer:
the molecules of each substance attract each other through dispersion (London) intermolecular force.whether a substance is solid, liquid or gas depends on the balance between the kinetic energies of the molecules and their intermolecular attractions.
thank you.
Answer:
<h3>i THINK HE WILL BE HUMAN who got smart phone</h3>
The answer should be 2) electrons.
The elements in the periodic table are arranged by increasing atomic number, which is also the number of protons in an element. For example, Carbon has 6 protons, it is the sixth element on the table. While Nitrogen, which has 7 protons, is after Carbon.
In atoms, the number of protons equals to the number of electrons too, if the number of electrons does not equal to the number of protons, the substance is no longer atom, but ion. So, the answer to this is 2) electrons, as the elements on the table is arranged according to increasing atomic numbers.
