Answer:

• the electron configuration for P iin complete form in order of increasing orbital energy is: 1s² 2s² 2p⁶ 3s² 3p³

Explanation:

As stated,  writing the symbol for the occupied subshell and adding a superscript to indicate the number of electrons in that subshell is a common way to represent the electron configuration of the atoms.

There are several rules that you have to follow to write such electron configurations. I will explain the needed to write the electron configuration for the atoms of P (phosphorus) in the requested form.

1) First, determine the number of electrons of the atom:

• Use the atomic number. Phosphorus has atomic number 15.
• The atomic number is the number of protons. So, phosphorus has 15 protons.
• A neutral atom has the same number of electrons than protons. So, phosphorus atoms have 15 electrons.

2) Fill the orbitals in order of incrasing orbital energy

• Aufbau rules are very helpful. As per it this is the order of the orbitals:

        1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d¹⁰ 4p⁶ 5s² 4d¹⁰ 5p⁶ 6s² 4f¹⁴ 5d¹⁰ 6p⁶ ...

• 15 electrons ⇒  1s² 2s² 2p⁶ 3s² 3p³
• Check the number of electrons: 2 + 2 + 6 + 2 + 3 = 15
• Hence, that is the electron configuration for P iin complete form in order of increasing orbital energy.

3) Other rules that you must consult to deal with some special issues of the electron configurations are: the exclusion principle of Pauli and the Hund's rule, but they are beyond the interest of this question.

C. a precursor for developing a disorder, but not a disorder on its own

Disordered eating is considered as a precursor for developing a disorder, however, it is not a disorder on its own.

• The disordered eating behaviors like dieting is one of the most common risk elements for the development of an eating disorder.

• It lies on the spectrum between the normal eating and an eating disorder and may comprise behaviors and symptoms of eating disorders, however, at a lower level of severity.

• It may comprise compulsive eating, restrictive eating, or irregular or inflexible patterns of eating.

• Some of the behaviors, which may signify that a person is involved in disordered eating is fasting, skipping meals, binge eating, using diet pills, and others.

Thus, the correct answer is option C.

Answer:

QS is 34

Step-by-step explanation:

We find x first. We set each side equal to each other to do so.

5x-3=21-x

6x=24

x=4

Next we find QS value. We add each side.

5x-3+21-x

4x+18

Then we plug in x to find numeric value.

4(4)+18

34

The value of QS is 30

QR = 5x-3

QR = 5x-3RS =21-x

Since, R is the midpoint of QR and RS ;

THEN ; = QS = QR + RS

5x - 3 = 21 - x

Solve for x

Collect like terms

5x + x = 21 + 3

6x = 24

Divide both sides by 6

x = 24 / 6

x = 3

QS = 5x - 3 + 21 - x

QS = 4x + 18

Put x = 3 in the equation :

QS = 4(3) + 18

QS = 12 + 18 = 30

The value of QS = 30
