Atom Flashcards
1
Q
How many electrons can each shell of an atom hold?
A
1st shell:2 electrons
2nd shell: 8 electrons
3rd shell: 18 electrons
4th shell: 32 electrons
2
Q
Formula to find number of electrons a shell can hold?
A
2(n^2)
where n is the shell number.
ex: n=2
so, 2(2^2)=2(4)=8
3
Q
How many electrons can each orbital hold?
A
s orbital-2 electrons
p orbital- 6 electrons
d orbital- 10 electrons
f orbital-14 electrons
