electronic structures Flashcards
1
Q
what is a shell
A
a shell is A area in an atom, around its nucleus, where electrons are found.
2
Q
how much can the first shell hold
A
the first shell ( which is the closest to the nucleus) can hold up 2 electrons
3
Q
how much can the second shell hold
A
the second shell can hold up 8 electrons
4
Q
how much can the third shell hold
A
the third shell can also hold up to 8 electrons
5
Q
what happens when there is more then 8 electrons in the third shell
A
if there is more the 8 electrons in the third shell then the electrons will go to the fourth shell
6
Q
what is the electronic structure
A
the electronic structure is a set of numbers to show the arrangement of electrons in their shell
