The electron configuration of a neutral atom is 1s22s22p63s2. Write a complete set of quantum numbers for each of the electrons.

Pavlova-9 [17]

Answer:

The four quantum number for each electron will be:

$1s^{2}$

$n=1;l=0;m=0;s=+\frac{1}{2}/-\frac{1}{2}$

$2s^{2}$

$n=2;l=0;m=0;s=+\frac{1}{2}/-\frac{1}{2}$

$2p^{6}$

$n=1;l=1;\\m=+1,0.-1 \\s=+\frac{1}{2}/-\frac{1}{2}$

$3s^{2}$

$n=3;l=0;m=0;s=+\frac{1}{2}/-\frac{1}{2}$

Explanation:

As the element is neutral, the number of protons will be equal to number of electrons which will be the atomic number of the element.

Number of electrons =12

Atomic number = 12

Element : Magnesium

The principal shell is represented by "n"

i) For "s" subshell the value of l =0 (azimuthal quantum number) thus m (magnetic quantum number)= 0

The two electrons in s subshell will have either plus half or minus half spin quantum number

ii) for "p" subshell the value for l =1

thus m = 0 or +1 or -1

The two electrons in each orbital will have either plus half or minus half spin quantum number

When a chloride solution of an element is vaporized in a flame, the color of the flame is violet. What element could be in the s

IgorLugansk [536]

Answer:

The answer to your question is Mercury

Explanation:

The flame test essay is used to identify the identity of a substance because most elements show different colors when in flame.

There are many elements that burn violet when in flame especially elements of the group IA like Potassium, Rubidium, Cesium and also Cyanide and Mercury located in different groups.

But the bibliography tells us that Mercury chloride burns violet so this element is the correct answer because there is chloride in the sample of this question.
