What is the number of the lowest energy level that contains an f sublevel?
The 4th energy level is the lowest that contains and f sub-level
What is the second quantum number for the electrons in the 4p energy sublevel of bromine?
The second quantum number (l) for the electrons in the 4 p energy sublevel of bromine would be 1.
What is the Principal Energy Level?
The quantum number relating to the size and energy of an orbital
What is the second quantum number for one of the electrons in the 4p energy sublevel of bromine?
l = 1
What could the third quantum number for one of the electrons in the 4p energy sublevel of bromine?
M1 = -1
What is the number of the lowest energy level that contains an f sublevel?
The 4th energy level is the lowest that contains and f sub-level
How do you find the number of orbitals in an element?
You would have to determine the electron configuration for atoms of a given element. Each s sublevel contains 1 orbital, each p sublevel contains 3 orbitals, each d sublevel contain 5 orbitals, and each f sublevel contains 7 orbitals. Click on the related link to see a periodic table that shows electron configurations for the elements.
How many electrons are in the first period?
for all elements, excluding hydrogen, there are 2 electrons in the first energy level. Hydrogen is the exception of this because it only has a single electron, thus it only has 1 in its first and only energy level.
What is the second quantum number for the electrons in the 4p energy sublevel of bromine?
The second quantum number (l) for the electrons in the 4 p energy sublevel of bromine would be 1.
What is the Principal Energy Level?
The quantum number relating to the size and energy of an orbital
How is the shape of an electron cloud determined?
It is a surface of constant probability i.e. an electron is just as likely to be found in a small volume anywhere around this surface. Energy sublevel
What is the largest number of d orbitals that can exist within the same energy sublevel?
5
What is the second quantum number for one of the electrons in the 4p energy sublevel of bromine?
l = 1
What could be the fourth quantum number for on of the electrons in the 4p energy sublevel of bromine?
ms -1/2
What could the third quantum number for one of the electrons in the 4p energy sublevel of bromine?
M1 = -1
What are the relationships between group configuration and group number for elements in the s p and d-blocks?
There are one or two electrons in the ns sublevel for s-block elements, the sum of electrons in ns and (n-1)d levels equals the group number in d-block elements, and the number of electrons in the np sublevel equals the group number minus twelve in p-block elements. You can find this info in table 2 on page 147 of the Modern Chemistry textbook.
