orbitals

Question 1

what is an atomic orbital?

Answer 1

circular path in which electrons revolve around the nucleus of an atom

Question 2

what are shells?

Answer 2

the electron in an atom is arranged in a shell that surrounds the nucleus. Electrons shells consist of one or more subshells

Question 3

what are subshells?

Answer 3

are a subdivision of electron shells separated by electron orbitals. Labelled as s,p,d and f in electron configuration consist one or more atomic orbitals

Question 4

formula to find the maximum number of electrons in a shell?

Answer 4

2n^2

Question 5

where are electrons found?

Answer 5

the electrons in a shell are found in regions called atomic orbitals

Question 6

how many orbitals does the s subshell have?

Answer 6

s subshell has 1 orbital

Question 7

how many orbitals does the p subshell have?

Answer 7

p subshell has 3 orbitals

Question 8

how many orbitals does the d subshell have?

Answer 8

d subshell has 5 orbitals

Question 9

what does 1s^2

Answer 9

1 tells you the energy level
s stands for the type of orbital
2 tells you the number of electrons in an orbital

Question 10

explain how the 2s and 2p. how many electrons do they hold? what order do the orbitals fill up in?

Answer 10

2s has a maximum of two electrons and 2p has a maximum of 6 electrons.
the 2s orbital has a slightly lower energy level than the 2p orbital
this means the 2s orbital will fill the electrons before the 2p orbital

Question 11

what is the difference between shells, subshells, and orbitals?

Answer 11

shells consist of one or more subshells
subshells consist of one or more orbitals
electrons in the same subshell have the same energy level, while electrons in different shells, subshells, and orbitals have different energies

Question 12

how does the energy of the s-orbital vary as you move from lower energy shell to higher energy shell?

Answer 12

when an electron moves from a lower energy level to a higher energy level, energy is absorbed by the atom
