Which orbital diagram represents nitrogen (atomic number = 7 )

Chemistry
1 answer:
yawa3891 [41]3 years ago
7 0

Answer:

Option A

Explanation:

The choice A accurately specifies and illustrates the orbital diagram of a Nitrogen atom with 7 electrons.

Based on the number of electrons in a Nitrogen atom, there are two energy levels, the s and p sub-levels:  

        Nitrogen  = 2, 5

The first energy level, S will take up two electrons with opposite spin.

The second energy level will have 5 electrons in an S and P orbital.

Configuration 1 is correct because, it satisfies the premise that half and fully filled orbitals are also stable.

The pH of a saturated solution of a metal hydroxide MOH is 10.15. Calculate the Ksp for this compound.
Airida [17]

Answer:

Ksp=2.00x10^{-8}

Explanation:

Hello!

In this case, since the pH of the given metal is 10.15, we can compute the pOH as shown below:

pOH=14-pH=14-10.15=3.85

Now, we compute the concentration of hydroxyl ions in solution:

[OH^-]=10^{-pOH}=10^{-3.95}=1.41x10^{-4}M

Now, since this hydroxide has the form MOH, we infer the concentration of OH- equals the concentration of M^+ at equilibrium, assuming the following ionization reaction:

MOH(s)\rightarrow M^+(aq)+OH^-(aq)

Whose equilibrium expression is:

Ksp=[M^+][OH^-]

Therefore, the Ksp for the saturated solution turns out:

Ksp=1.41x10^{-4}*1.41x10^{-4}\\\\Ksp=2.00x10^{-8}

Best regards!

Dvinal [7]

Answer:

1.  Previous Eye Surgery .

Explanation:  

1. Your medical history can also affect your vulnerability to cataracts. For instance, a previous eye surgery can cause secondary cataracts. Other conditions including diabetes and excessive use of steroids accelerate the chances of cataracts once a person has already undergone previous eye surgeries.
