Which types of electron orbitals will have higher energy than a 4d orbital?

alexdok [17]

Answer:

D) 4f

Explanation:

To determine which electron orbital that will have higher energy than a 4d orbital, we write the electron configuration starting with s-orbital.

2s 2p

3s 3p 3d 3f

4s 4p 4d 4f

5s 5p 5d 5f

6s 6p 6d 6f

7s 7p 7d 7f

In ascending order, 1s, 2s, 2p, 3s, 3p, 4s, 3d, 4p, 5s, 3f, 4d, 5p, 6s, 4f, 5d, 6p, 7s, 5f, 6d, 7p, 6f, 7d, 7f.

From the electronic configuration formula above, the electron orbitals that have higher energy than a 4d orbital are 5p, 6s, 4f, 5d, 6p, 7s, 5f, 6d, 7p, 6f, 7d, 7f.

Therefore, 4f is the correct answer.

Find the density of a material given that a 5.03g sample occupies 3.24ml

Verizon [17]

Formula for density:

D = Mass / Volume

Mass = 5.03g

Volume = 3.24ml

Formula in our case:

D = 5.03 / 3.24

$D = 0.31~g/m^{3}$

Hope it helped,

Sinkholes are often formed as a result of the actions of...

enyata [817]

Swallow hole is also known as a sinkhole refers to a hole or depression in the ground resulted due to certain kind of collapse of the surface layer. The majority of them are the result of karst procedures, like the suffosion processes or the chemical dissolution of the carbonate rocks.

The sinkholes differ in size from 1 to 600 meters, both in depth and diameter, and differ in form from soil-lined bowls to bedrock-edged chasms. The sinkhole may get produced suddenly or slowly, and are observed all through the globe.
