Answer : The values of all the quantum numbers for one electron in the 2p sublevel of a nitrogen (N) atom are, $(n=2,l=1,m_l=-1,0,+1,m_s=+\frac{1}{2}\text{ or }-\frac{1}{2})$

Explanation :

There are 4 quantum numbers :

Principle Quantum Numbers : It describes the size of the orbital. It is represented by n. n = 1,2,3,4....

Azimuthal Quantum Number : It describes the shape of the orbital. It is represented as 'l'. The value of l ranges from 0 to (n-1). For l = 0,1,2,3... the orbitals are s, p, d, f...

Magnetic Quantum Number : It describes the orientation of the orbitals. It is represented as m_l . The value of this quantum number ranges from $(-l\text{ to }+l)$ . When l = 2, the value of m_l will be -2, -1, 0, +1, +2.

Spin Quantum number : It describes the direction of electron spin. This is represented as m_s The value of this is $+\frac{1}{2}$ for upward spin and $-\frac{1}{2}$ for downward spin.

The electronic configuration of nitrogen atom is, 1s^22s^22p^3

Now we have to calculate the values of all the quantum numbers for one electron in the 2p sublevel of a nitrogen (N) atom.

For 2p^1 :

n=2 (Because it is in 2nd shell)

l=1 (Because it is in 'p' orbital)

m_l=-1,0,+1 (Because l = 1)

$m_s=+\frac{1}{2}\text{ or }-\frac{1}{2}$ (Because of the sign convention)

Therefore, the values of all the quantum numbers for one electron in the 2p sublevel of a nitrogen (N) atom are, $(n=2,l=1,m_l=-1,0,+1,m_s=+\frac{1}{2}\text{ or }-\frac{1}{2})$

Answer from: Quest

explanation:

venn diagram is pictorial representation with of circles showing the relation between two finite sets or things. the intersection part of two circles conveys the relation present in between those sets or things.

here in the venn diagram of sand and salt two circles represent sand and salt. but the area falling under the intersection of these circle represents the mixture of sand and salt.

so, in a venn diagram the mixture will be placed in a middle that is in between the intersection of two circles.

Alpha particles have positive charge, beta particles have negative charge, and answer 4 just doesn’t make sense. thus, you are left with only one possible answer.

Air pressure is measured in pascals. for a professional american football game, the ball should be inflated to about 90,000 pascals. scientists studied the effects of air temperature on the pressure inside american footballs by taking these steps: 1. prepare 100 footballs. 2. measure each football's air pressure. 3. divide footballs into 10 groups. 4. place the groups in different lockers cooled to different air temperatures. 5. after 12 hours, remove the footballs from lockers. 6. measure each football's pressure again. 7. compare the new pressures to the starting pressures. what two terms best describe the variable "air pressure inside the football" in this experiment? independent, qualitative independent, quantitative dependent, qualitative dependent, quantitative
