Which best describes ionization energy?
energy needed to add an electron to a neutral atom in the gas phase
energy needed to add an electron to a neutral atom in the liquid phase
energy needed to remove an electron from an atom or ion in the gas phase
energy needed to remove an electron from an atom or ion in the liquid phase

they include patterns; cause and effect; scale, proportion, and quantity; systems and system models; energy and matter; structure and function; and stability and change.

can i get the brainiest answer

i answered it first

the answers would be

the first one and the second one

is there any options? maybe im just not seeing them but i need the options to

-love shrooms

on passing the small ampere of electric current through the tube made of ar and hg of cfl generates uv rays which excites the fluorescent and thus emits the high radiation by consumption of just 5- 12 w in comparison to incandescent light which requires more power such as around 40 - 55 w to lighten.

moreover the life span of fluorescent or cfl is around 8000 h whereas the life span of incandescent is around 1200 h

hence, the building installed with incandescent lights bears more electricity bill.
