What is the maximum number of electrons that can occupy one orbital

Chemistry
2 answers:
olga nikolaevna [1]3 years ago
8 0

Explanation: The first shell can hold 2 electrons and the next one can hold 8. So, if we have an atom like boron which has 5 electrons, we would put 2 electrons in the first shell and we would put our remainder in the second shell.

I will attach an image with a boron atom and with the electrons.

1.6x10^23 lead atoms. Find the weight in grams
Ber [7]
Moles of lead(Pb) = 1.6x10^23/6.02x10^23 = 0.265 moles.

Weight of lead = moles x atomic weight of lead
                         =  0.265x207.2
                         =  54.908 grams.

Hope this helps!

liam uses a machine that counts waves on a metal cable. The machine counts 25 waves in 2 seconds. what is the frequency of the w
Softa [21]
Frequency is defined as the number of waves per second. In this machine 25 waves pass in one second.
We need to calculate the number of waves that pass a particular point during one second.
During 2 seconds -25 waves
Therefore in one second - 25/2 = 12.5 waves/s.
1 wave per second has the unit Hertz (Hz)
Therefore answer is 12.5 Hz

What is the charge on an ion that has an atomic number of 16 and contains 14e-?
lora16 [44]
The answer would be 2+ since the atomic number represents how many protons are in the element. In this case, there are 16 protons, but only 14 electrons, which means there are an additional 2 protons, hence the 2+ charge on the ion.

If you have 40 grams of potassium nitrate in 100 grams of water at 20 C:
anygoal [31]

Answer:

Explanation:The final homogenous solution, after cooling it to 40°C, will contain 47 g of potassium sulfate disolved in 150 g of water, so you can calculate the amount disolved per 100 g of water in this way:

[47 g of solute / 150 g of water] * 100 g of g of water = 31.33 grams of solute in 100 g of water.

So, when you compare with the solutiblity, 15 g of solute / 100 g of water, you realize that the solution has more solute dissolved with means that it is supersaturated.

To make a saturated solution, 15 grams of potassium sulfate would dissolve in 100 g of water.

Deduce the charge of Z ,in the compound of ZBr2
lyudmila [28]

Answer:

2+

Explanation:

The charge on Z in the compound ZB₂ is a 2+  

  From the given compound:

   We know that Br is bromine with a charge of -1;

So;

   Using the combining power approach:

Atoms                              Z                                Br

Combining power           2                                1

Exchange of valency      1                                 2

So;

  The charge on Z is  2+

          2
