The following combinations are not allowed. If n and ml are correct, change the l value to create an allowable combination:
motikmotik

The allowable combination for the atomic orbital is n=3, l=1, m_{l}=-1.

<h3>What are the three quantum numbers of an atomic orbital?</h3>

Three quantum numbers specify an atomic orbital:

- The principal quantum number, n, which is a positive integer, describes the relative size of the orbital and its distance from the nucleus.

- l is the angular momentum quantum number that is related to the shape of the orbital; l is an integer from 0 to n-1 (so n limits l ),

- $\boldsymbol{m}_{l}$ is the magnetic quantum number that prescribes the three-dimensional shape of the orbital around the nucleus; m_{l} values are integers from -l to =l(l limits ml)

For n = 3, l can have three values: 0, 1, and 2. Since m_{l} values are integers from -l to 0 to +l, for l = 0 the value of m_{l} cannot be -1 (l = 0 has m_{l}= 0).

There are two l values that are consistent with n and m_{l} values:

l=1 or 2

Therefore, the allowable condition is n=3, l=1, m_{l}=-1.

Lily is doing a science experiment with a substance in a sealed jar. At first, the substance's molecules are moving around each
Alex

The molecules will be more separated, and will have least amount of intermolecular force of attraction.

<h3><u>Explanation:</u></h3>

The molecules inside the jar of Lilly are moving around each other. This means the state of the matter present inside the jar is liquid. As Lily gives more energy inside the jar , the molecules inside the jar will get more separated as the kinetic energy of the molecules increase and the intermolecular force of attraction decreases as well as the intermolecular separation or distance increase. As the energy is continued to be supplied from outside, there will be a time when this liquid will reaches boiling point and will start to change into gas. After this point the intermolecular force of attraction will be least among molecules and their separation will be maximum.

One isotope of a metallic element has the mass number 63 and 33 neutrons in the nucleus. The cation derived from the isotope has
katen-ka-za [31]

Given

Mass number of isotope = 63

Number of neutrons = 33

So number of protons = 63 - 33 = 30

Hence atomic number of metal = 30

thus metal is = zinc

now as it is forming cation with 28 electrons it means it has lost two electrons so it must have a dipositive charge

the symbol of metal ion will be

Zn^+2
