Hydrogen is grouped with the alkali metals because they are grouped based on their properties and behavior, and like the other elements in Group 1 (1A), it only has one valence.

Jet001 [13]
Reduction <span>always results in a lowering of the oxidation number. The reaction of the system above is written as:

</span><span>Cu2+(aq) + Fe(s) --> Cu(s) + Fe2+(aq) 
</span>
From the reaction, we see that copper goes from the +2 to a neutral charge. Lowering of the oxidation number happens so this is the element that is being reduced.

Leya [2.2K]

Answer:

the effect of oxygen on these types of microbes is it will kill them.

Explanation:

When oxygen present in the environment come in contact with anaerobe bacteria it kill them because oxygen in air act as excited oxygen singlet molecule which will react with the water present in the cell of bacteria and convert it into hydrogen peroxides and bacteria do not have any defense system from hydrogen peroxide and ultimately it kill the bacteria.

State which of the following set of quantum number would be possible and which would be permissible for an electron in an atom.
raketka [301]

Answer:

The correct option is: e) n=4, l=3, m_{l} = - 2 , m_{s} = - 1/2                                              

Explanation:

The four quantum numbers that describe the electrons in an atom are: The principal: n, azimuthal: l, magnetic: m, and  spin: s.

For a given electron, the values of the quantum numbers should be in the <u>given range</u>- principal quantum number: n ≥ 1;

azimuthal quantum number: 0 ≤ l ≤ n − 1;

magnetic quantum number: −l ≤ m_{l} ≤ +l;

spin quantum number: −s ≤ m_{s} ≤ +s

Now, for n= 4,

The value of l: 0 to n − 1 =  0 to 3 = 0, 1, 2, 3

The value of m_{l} for l= 3 : -3 to +3 = -3, -2, -1, 0, +1, +2, +3

The value of m_{s}: -1/2, +1/2

<u>Therefore, the given set of quantum numbers</u>: n=4, l=3, m_{l} = - 2 , m_{s} = - 1/2;  <u>are possible and permissible for an electron in an atom.</u>
