Which statement about the quantum mechanical solution for the hydrogen atom is INCORRECT? Group of answer choices

A. The ms quantum number is always a fraction.

B. The principle quantum number, n, can have a value of 1.

C. The ml quantum number must have a positive value.

D. The angular momentum quantum number l = 1 corresponds to the p subshell.

C. The ml quantum number must have a positive value.

Explanation:

The single electron in hydrogen can be found in a ground state orbital of 1s having a magnetic quantum number ml = 0.

Similarly, this one electron can be excited to other higher energy levels such as 2p, 3p, 3d etc

The magnetic quantum numbers ml for higher np sub-levels of the hydrogen atom have magnetic quantum numbers; -1, 0 and 1.

The nd sub-levels have magnetic quantum numbers; -2, -1, 0, 1, 2. We can see from the foregoing that magnetic quantum number ml for hydrogen atom is not always positive.

when the volume of gas is   changed from   717.73 ml   to 852 ml   the temperature will   change   from 315   c to 452   c

    calculation

this is calculated using the charles law formula

that is,   v1/t1 = v2/t2

          v1=?

        t1 = 315 c   into   kelvin = 315 +273 = 588 k

        v2 = 852   ml

        t2 = 425c + 273 =698 k

make v1   the subject of the formula ( by   multiplying both side by t1)

  v1=( v2 xt1) / t2

v1= (852 ml   x 588 k)/ 698 k= 717.73 ml
