Explanation:
Atoms are at their most stable when their outermost energy level is either empty of electrons or filled with electrons. Sodium atoms have 11 electrons. Two of these are in the lowest energy level, eight are in the second energy level and then one electron is in the third energy level.
Polaris the north star is very bright and it doesn’t move
Answer:
The proton remains the same.
Explanation:
Oxidation is simply defined as the loss of electron(s) during a chemical reaction either by an atom, molecule or ion.
Oxidation is strictly on the transfer of electron(s) and not proton.
A metal that undergoes oxidation still has its protons intact otherwise it will not be called the ion of the metal since atomic number is called the proton number.
Sodium (Na) undergoes oxidation as follow:
Na —> Na+ + e-
Na is called sodium metal.
Na+ is called sodium ion.
Na has 11 electrons and 11 protons
Na+ has 10 electrons and 11 protons
From the above illustration, we can see that the protons of Na and Na+ are the same why their electrons differ because Na+ indicates that 1 electron has been loss or transferred.
Answer:
change the concentration of one reactant while keeping the other concentrations constant
Explanation:
For a given reaction;
A + B --> C + D
The reaction rate may be given as;
Rate = k[A][B]
In the above rate equation, the orders of both reactants ( A and B) is 1 . Reaction order is basically how the concentration of the reactant affect the rate of the equation.
The correct option is;
change the concentration of one reactant while keeping the other concentrations constant.
That way, one can monitor how a particular reactant affect the rate of the reaction.
