Question

why electronic energy is negative​

Answer 1

Explanation:

Electrons are always marked negative Hence electronic energy is also always taken as negative. It is because when an electron is at infinite distance from nucleus , there the kinetic energy of that electron can not be calculated. So, it is taken to be zero . ... And thus the energy of electron becomes less negativ

Answer 2

electrons are always marked negative hence electronic energy is also taken as negative. It is because when an electron is at infinity distance from nuckeus, there the kinetic energy of that electron can not be calculated. so, it is taken to be zero. ...... And thus the energy of electron becomes less negative
