The following combinations are not allowed. If n and ml are correct, change the l value to create an allowable combination:
Lera25 [3.4K]

The allowable combination for the atomic orbital is n=4, l=2, m_{l}=2.

<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 = 4, l can four values: 0, 1, 2, and 3. To be consistent with m_{l}=+2the l value must be higher than 1. There are two l values that are consistent with n and m_{l} values:  l= 2 or 3

Therefore, the allowable condition is n=4, l=2, m_{l}=2

How many moles of water, H2O contain 2.0x10^22 molecules of water
Licemer1 [7]
I mole of water has an Avogadro number of molecules.

1 mole = 6.02 * 10^ 23  molecules.

6.02 * 10^ 23  molecules  =  1 mole of water
 
1 molecule                        =  1/(6.02 * 10^23)  mole of water

2.0 * 10^22 molecules would have   =    (2*10^22) * 1/(6.02*10^23)

                                                             = 0.033

2* 10 ^22 molecules of water would have 0.033 moles of water.

Atomic theory as it is known today is the result of the contributions of many scientists who did the research, disproved old mod
Elena L [17]

Answer:

The contributions are not listed in the question. I guess the following are the options you are talking about.

Same elements have same properties:

In 1803 Dalton gave the atomic theory that the properties of the atoms of the same element are same.

Electrons in Orbits:

Electrons were discovered in 1897 by J J. Thompson but the hypothesis of electrons in the orbits were given by Hantaro Nagaoka in 1904.

Plum pudding model:

Plum pudding model was given by J. J. Thompson in 1904 with the concept of positively charged medium containing the negatively charged electrons in it.

Positively Charged Atomic Nucleus:

Earnest Rutherford in 1911 discovered the positively charged atomic nucleus.
