Which of the following is a possible Noble gas notation? [Xe] 6s26p6 [Kr] 5s25d85p6 [Xe] 6s25d106p4 [Kr] 5s24d105p6
Mice21 [21]

Answer is: [Kr] 5s24d105p6.

1) [Xe] 6s²6p⁶ is not correct, because element with atomic number 62 (54 + 8) is samarium with electron configuration [Xe] 6s²4f⁶.

Xenon (Xe) is noble gas with atomic number 54, which means it has 54 protons and 54 electrons.

Electron configuration of xenon atom:  

₅₄Xe 1s² 2s² 2p⁶ 3s² 3p⁶ 3d¹⁰ 4s² 4p⁶ 4d¹⁰ 5s² 5p⁶.

2) [Kr] 5s²5d⁸5p⁶ is not correct, because element with atomic number 52 (36 + 16) is tellurium.

Tellurium (Te) is an element with atomic number 52 (52 protons and 52 electrons), it is in group 16 (chalcogens) and period 5 (principal quantum number n = 5, which means it has 5 electrons shell) of Periodic table.

Electron configuration of tellurium atom:

₅₂Te 1s² 2s² 2p⁶ 3s² 3p⁶ 3d¹⁰ 4s² 4p⁶ 4d¹⁰ 5s² 5p⁴ or [Kr] 4d¹⁰5s²5p⁶.

Krypton is a chemical element with symbol Kr and atomic number 36, which means it has 36 protons and 36 electrons.

Electron configuration of krypton atom:  

₃₆Kr 1s² 2s² 2p⁶ 3s² 3p⁶ 3d¹⁰ 4s² 4p⁶.

3) [Xe] 6s²5d¹⁰6p⁴ is not correct, because element with atomic number 70 (54 + 16) is ytterbium (Yb) with electron configuration [Xe] 6s²4f¹⁴.

4) [Kr] 5s²4d¹⁰5p⁶ is correct, because element with atomic number 54 (36 + 18) is krypton (Kr) with electron configuration 1s² 2s² 2p⁶ 3s² 3p⁶ 3d¹⁰ 4s² 4p⁶ or [Kr] 5s²4d¹⁰5p⁶.

A sample of an ideal gas at 1.00 atm and a volume of 1.82 L was placed in a weighted balloon and dropped into the ocean. As the
Anvisha [2.4K]

Answer:

The answer to your question is Volume = 0.12 L

Explanation:

- Data

Pressure 1 = 1 atm

Volume 1 = 1.82 L

Pressure 2 = 15 atm

Volume 2 = ?

Temperature = constant

- Formula

- To solve this problem use the Boyle's law

            P1V1 = P2V2

- Solve for V2

            V2 = P1V1 / P2

- Substitution

             V2 = (1)(1.82) / 15

- Simplification

             V2 = 1.82 / 15

- Result

             V2 = 0.12 L

How are crystals made? ​
Step2247 [10]

Explanation:

Crystals often form in nature when liquids cool and start to harden. Certain molecules in the liquid gather together as they attempt to become stable. They do this in a uniform and repeating pattern that forms the crystal. In nature, crystals can form when liquid rock, called magma, cools.

What effect does the pH of water have on radish seed germination?”​
yuradex [85]
Even though the radishes watered with a 5.6 pH grew the best, they did not turn out to be the healthiest. The 7 pH radishes grew the most thick and sturdy. In conclusion, radishes watered with a low pH level do not grow to be tall and radishes watered with an exact acid level to neutral grow to be tall.
