State which of the following set of quantum number would be possible and which would be permissible for an electron in an atom.
a) n=3, l=3, m l =+3 , m s = +1/2
b) n=3, l=0, m l =+1 , m s = - 1/2
c) n=5, l=4, m l =+3 , m s = 1
d) n=0 ,l=0, m l = 0 , m s = +1/2
e) n=4, l=3, m l = - 2 , m s = - 1/2

The correct option is: e) n=4, l=3, = - 2 , = - 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 given range- principal quantum number: n ≥ 1;

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

magnetic quantum number: −l ≤ ≤ +l;

spin quantum number: −s ≤ ≤ +s

Now, for n= 4,

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

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

The value of : -1/2, +1/2

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

explanation:

the term hydride is commonly named after binary compounds that hydrogen forms with other elements of the periodic table. hydride compounds in general form with almost any element, except a few noble gases. the trends and properties vary according to the type of intermolecular force that bonds the elements together, the temperature, its molecular masses, and other components. hydrides are classified into three major groups, depending on what elements the hydrogen bonds to. the three major groups are covalent, ionic, and metallic hydrides. formally, hydride is known as the negative ion of a hydrogen, h-, also called a hydride ion. because of this negative charge, hydrides have reducing, or basic properties. its special characteristics will be further discussed.
