Question

can you explain electron configuration....and please tell me how is this reasonable
potassium=2,8,8,1
copper=2,8,18,1
how???
please explain to me why​

Answer 1

Answer:

Electronic Configuration is way of representing the shells of a atom

Explanation:

In case of pottasium its atomic number is 19

it's shell is k2,L8,M8,N1

so it's valency is 1

so POTTASIUM has 4 outer shells, the atoms at the last she'll try to attain nearest Noble gas confirmation that is they loose or gain electron

Since pottasium is a metal it looses electron to become electro possitive

I don't understand in your question about copper may be it's a mistake

Answer 2

electronic configuration is a diagram which shows the electrons or protons of any atom
